Davidsonand the last purportedly in Gujarat over 30 yearslater by R. Meinertzhagen. Becauseof recendy documented specimenfraud by Meinertzhagen,we sublectedhis Forest Owlet specimento scrutiny (including X-raysJ and establishedthat it had been extensivelyremadein a way that transformedits original appearance.Moreover,it shows severalfeatures- tying of distal humeri from the outside,cotton wing-stufffngidenticalto that from a Davidsonbird, original retention of humerus and forme y a stretchedneck that identif its true collectorasDavidson.Exarninationof the Natural History Museum's cataloguerevealsthat a fifth Davidsonspecimen,collectedin 1884 in the areawhere his ffrst four were taken, was registeredin 1925 but is now missing,although not loggedas lost, sold or exchanged.Meinertzhagen'sdiary and specimencataloguestrongly suggest that he was not in Gujarat on the date given for his l9l4 specimen, and he surprisinglynever published the record, despite its exceptionalrarity. We concludethat he stolethe fifth DavidsonForestOwlet specimenfrom the Natural History Museum,and remade and relabelledit to concealits origin, thereby compromisingthe geographicand temooral record of this criticallv threatenedsoecies. The Forest OwLet HeterogJaux (Athene auct.) bbwixi was until 1997 (King & Rasmussen1998J only known from sevenold specimenq all collected in central India. The type specimen was collected in eastern Madhya Pradeshin 1872, while a bird was obtained 100 km to the south in Orissa in 1877, four were taken 900 km to the east in northwest Maharashtrain 1880-83 by J. Davidson and one was purportedly taken in Gujarat in l9l4 by R. Meinertzhagen (Fig. l). Recent documentation of specimen fraud perpetrated by Meinertzhagen in redpolls ,4canthk spp. (Knox 1993) led us to question the reliabllity of the entire Meinertzhagen bird skin collection. This resulted in the discoverythat falsiffcation of data is common among Meinertzhagen's Indian subcontinent specimens (BOU Council 1997, Rasmussen 1998, Rasmussen & Prys-Jonesunpubl. data) and prompted us to consider the possibility that his 1914 Forest Owlet might have a different history from that indicated by the label data. As this specimen 'Corresponding author Email:[email protected] o 1999 Brilish Ornithologists'ljnion was claimed to have been collected some 30 yearsafter all other known material and at a new locality, the question ofits authenticity clearly bearson the species' conservation standing, the ramiffcations of which are discussedelsewhere(Rasmussen& Collar 1998). Based on morphological comparisons,we resurrect for bleuittr the monotypic genus Haeroglaux (Rasmussen & Collar unpubl. data). IIETHODS Forcat Owlet specimens Six museum specimens of the Forest Owlet were mentioned by fupley (1976); four of them at the Natural History Museum (BMNH), including the t1pe, two Davidson specimensand the Meinertzhagen skin (Knox & Walters 1994); with two more Davidson specimens at the Museum of Comparative Zoology, Harvard University IMCZJ and the American Museum of Natural History (AMNHJ, respectively, both having been exchanged from BMNH. All the above- 12 PC. Rasmussen& N.J. Colal Figure1. Mapof localities fromwhichsp€cimsns ol the Fo.est Owletoriginate. mentioned specimenswere thus once held at BMNH; four of them (including the type and three of Davidson's) as pan of the Hume Collection. The second specimen collected, that from Karial, Orissa (Ball 1877, 1878), is held in the National Museum of Ireland, Dublin. Thus, all seven published Forest Owlet specimensare currently extant and accounted for (Table 1), and five are shown in Figure 2. ln searching for other, unpublished material of the Forest Owlet (Appendix l), we examined the BMNH register of the Hume Collection, but found no specimen beyond those above (Hume's original catalogue was stolen and destroyed: E. Moulton unpubl. data). However, the register of the Davidson Bequest, which is not in taxonomic order, records an additional unpublished specimen as Caitle noctua bleufiri (BMNH 1925.12.23.958, male, Taloda, Khandesh, 4 December 1884). Although tJrere is no annotation in the register indicating its exchangE losq destruction or other transfer, no corresponding specimen is now present in BMNH. This skin has evidendy been missingsincebefore 1975, otherwise its existence would have been known to fupley, who in April of that year requested the loan of BMNH holdings apart from the type (Smithsonian Institution Archives Accession 92-063). He later stated 'l borrowed ffve of the half dozen known specimens' (Ripley 1976), indicating that he knew ofjust four at BMNH. Ali (19781, unaware of Ball's specimen in Dublin, wrote that tupley 'brought together all the available material of A. bbwitti'. Certainly this fffth Davidson Forest Owlet specimen was unavailable when researchwas being done fqr Knox and Walters (1994J in tlre mid-l980s (M.P Walters in litt. 7997). It would have brought the total number of knom specimensofthe ForestOwlet to eight, but for the fact that cursory examination of Meinertzhagen'sspecimen had already raised our suspicions. Conparisonof piaparationtechniques To evaluatethe autlenticity of Meinertzhagen'sForest Owlet specimen, we studied the techniques and materials used in its preparation by external examination, radiographs and analysis of stuffing fibres. We attempted to discriminate Meinertzhagen's earlycentury preparation style of small owls by doing similar examinations of 18 of his specimensof Little Owl Athme noctua in the Rothschild Collection (now at AMNH) and ten of his Spotted Owlets IBMNH 1965.M.5214-5223,Deccanand Madras,1901, 1937; Table1.

To ascertain Meinertzhagen's general preparation style in 1914, sevenofhis Poona(Pune) specimens from between 3 September and 2 October l914 were examined and X-rayed, these being the closest in Meinertzhagen'scollection register to the claimed site and date of his Forest Owlet specimen (Mandvi, 9 October l9l4). To evaluate the authenticity of the 13 above Meinertzhagen Little Owlq their preparation styles were compared among the seriesas well as with eight Middle Eastem Little Owls that initially appeared similarly prepared (collected by Lynes, Rothschild, Hartert, Hilgert, Nicoll, Riggenbach and Flnkiger; all AMNH Rothschild Collection specimens) and plumage condition and moult stagewere checked for seasonal appropriateness. In addition, supplementary data and X-rays are available on preparation stylesof severalhundred specimensofother Asian taxa from the Meinertzhagen Collection and other collectors (Rasmussen& Prys-Jonesunpubl. data), including l2 putative Meinertzhagen specimensof small owls of other genera. To examine the possibility that the Meinertzhagen ForestOwlet might be the missingDavidson specimen, detailed comparisonswere made with the four extant Davidson Forest Owlet skins; with a Jungle Owlet Glaucidium radiatum (BMNH 1925.12.23.960) collected by Davidson at the same locality aq and just two days after, the missing Forest Owlet; and with Davi&on's other owl specimens in BMNH (17 of which were X-rayed). To evaluate the distinctiveness of Davidson's preparation style, we randomly sampled lndian owl specimens from other collectors. X-rays (radiographs]ofthe above specimenswere made in the fish divisions of BMNH, AMNH and USNM, using either Ready-packKodak Industrex-M film or SR fflm, and settings of 30 kV and l0 mA for an exposure of 40 s; 30 kV and 3 mA for 2 min, and 25 kV and 5 mA for 30 s, respectively.To obtain comparative samples of original cotton stuffing, J. P Angle made an incision in the underwing skin along the ulna on the Meinertzhagen Forest Owlet and the Davidson Jungle Owlet. These samples were compared microscopically and instrumentally using a standardbattery offorensic tests by D.W Deedrick, Chief, Tiace Evidence Unit, Federal Bureau of lnvestigation (FBIJ. To allow interpretation of the circumstances surrounding the collection of the Mandvi specimen, PCR examined the October 1914 entries of Meinertzhagen's diary deposited at Rhodes House Library Oxford University. NESULTS Evidenc€ to? the rcmaking of Ueine zhagenb Forcst Owlet ComDressionof neck Althoughhiddenby feathersandnot readilydetected, the neck skin of Meinertzhaeen's ForestOwlet has union,/b,i 14'1,11-21 o 1999BritishOrnilhologists' 14 PC. Rasmussen& N.J. Collar been extensively and neatly folded under (Fig. 3a), with one major and at least one smaller fold. This feature is more obvious on X-rays (Fig. 4aJ, which show the major fold to be about l5 mm wide all round the neck. If folding had taken place at the time of original preparation, the skin would simply have shrunk back; the sharp buckling now present is clear evidence of the neck being compressedinto the body well after the skin was dry lncision and stitching The ventral incision of the Meinertzhagen specimen is a very long opening, now loosely stitched by doublestranded blue thread, but the portion over the breast has one clearly visible old needle-and-threadhole by which the skin was once stretched and dried, aswell as other torn, raggedlydried edges(Fig. 3b). The present stitching does not match the old hole or torn edges,nor does it follow the stretched edges of the skin. The ponion of the incision over the belly, however, has no old stitching holes, but has cleanly cut edges (Fig. 3cJ which have not shrunk back as they do when fresh specimeosdry The nature of the ventral incision indicates that Meinertzhagen'sForest Owlet rvasextensively remade some time after original preparation. The only plausible explanation for the failure ofthe present stitching over the breast to match an old needle hole or follow the skin edges is that the odginal stitching was removed some time after the specimen was completely dry and new stitching put in. Moreovet the clean edgesofthe abdominal part ofthe incision and the lack of subsequent shrinkage indicate that this cut must also have been made after the specimen was fully dry. A loosely sewn incision with double-stranded thread would place minimal strain on the delicate skin edgeE and is a common feature of remade specimens in Meinertzhagen's collection (Rasmussen& Prys-Jones unpubl. data), and one that we have rarely seen in specimensthat bear no other indications of remaking.

(Lowestphoto: H. Taylor) Union,/bis, t4t, 11-21 O 1999BritishOrnfihotogists' Absence of oil The Meinenzhagen specimen is the only Forest Owlet skin that does not have grease-stainedfeathers around the incision,or obviousoil on the feet and bill. Instead, unlike the other Forest Owlets, it has a white powdery residue on the feet and bill, and the bill appears bleached (as opposed to dull orange in all the others). These features are consistent with the specimen having been treated with a solvent. It is unlikely that any individual of this almost certainly non-migratory owl would have had more than a moderate fat laver and it is thus improbablethat its collectorwould have gone to the considerabletime and trouble involved in washing it with a solvent during original prepalation. 16 PC. Rasmussen& N.J. Collar in the Meinertzhagen specimen, and the loss of much ofthis bird's skull may have been an inadvertent result of removal of the articular region, perhaps owing to the britdeness of long-dried bones. Davidson left the femora in his other Khandeshspecimenq which would have made the legs very difficult to reposition, so it is likely that the femora were removed in the remaking of Meinenzhagen's specimen. Repositioning of an originally improperly dried wing (as were some of Davidson'sJwould be facilitated by breakageor disarticulation of the wing bones. Comparbonr with rloine zhagen' owl speclmens Becauseof the questionable provenance of many of Meinertzhagen'sspecimeng the featuresofhis genuine preparation style are difffcult to determine. Our efforts to establish his early-century preparation style for small owls have been hampered by the considerable differencesbetween many specimensin his collection, some of which match specimens from other collectors's seriesfor which specimensare missing. However, except for two birds noted below, all his A. nactua lilith and A. n. gJaux In LMNH show consistency within and to a lesser extent between series (Fig. 5a, 5b), aswell asbeing broadly similar in style to several other Meinertzhagen .4drenr specimens (e.g. nocraa, BMNH 1965.M.5160-5163, 5167; brama, BMNH 1965.M.5214-s2r8, 5223-5224;Fig. sd). Alsq we have not located other collectors' specimens that closely match the Meinertzhagen Little Owl series.[n addition, the AMNH Litde Owls appear to be in seasonally appropriate plumage, unlike many questionable Meinertzhagen specimens,so all indications are that this material bears genuine data. However, two specimens from this series - both of A. n. lilith (AMNH 631339-631340 - are prepared very differendy from the others, and have clearly been remade, albeit not in the same manner as the Fotest Owlet; their provenance must also be considered dubious. The Meinertzhagen owl temporally closestto his Forest Owlet is a Spotted Owlet [Fig. 5c, BMNH 1965.M.5220) purportedly collected at Quetta on 6 April l9l4; tlis specimen, however, bears little similarity in style to any of the other Meinertzhagen owls studied, and again may not bear genuine data. Of 48 small owls ostensibly collected by Meinertzhagen, including 30 in the Meinenzhagen Collection and l8 Litde Owls in the Rothschild Collection, only one A. n. hAlaw| the Tibetan race - bears any compelling resemblancein preparation style to that of his Forest Ornithologists' union.,bis,141,|1-2'l o 1999British Owlet. This specimen, purportedly collected by Meinertzhagen on the Tibet-Sikkim border, is almost certainly fraudulent as well (Rasmussen& Prys-Jones unpubl. data). Charecterlatlcs rp€cimens ol feineltzhagon Pune lPoonal A Meinertzhagen seriesfrom Pune collected between 3 September and 2 October 1914 {BMNH 1965. M.s72s, 6043, 6113, 9898, 9934, 542-lrs43) shows a consistentextemal preparation style, with the hea& at least slightly tumed; long thin necks, understuffed bodies, crossed legs and no external support stick. The incisions on all are rather low and sewn with beige to brown thread, and each has similar small dark flakes of a sawdustlike material in the somewhat oily feathers around the incision- X-rays (one shown in Fig. 5e) confirm their similarity; the back of the skull was cut off on six of the seven specimens;the humeri were broken just below their heads(except in one witl shattered wing bones); and the wings are positioned asymmetrically. Most characteristically, the short support stick was wrapped with stuffing material and at Ieast sometimes with thread wound over that; the neck skin dried close to the stick in these specimens and appearsundisturbed, indicating that tlle 'cottoned' stick was used in the original preparation. Finally, the plumage condition of each specimen seemsseasonally appropriate. All indications, thereforg are that the Puneseriesmay bear genuinedata. It will be noted that the characteristicfeaturesofthe Pune series are not present in Meinertzhagen's Forest Owlet specimen, although the latter was purportedly collected just seven days after the last of the former Comparison of the Meinertzhagen Forest Owlet (Fig. 4a) with an Indian Roller Coracias bengabnsis from his Pune series (chosen becauseof the species' comparable size: Fig. 5e) confirms this lack of resemblance in style. Comparisor of Davidson specimens and Ieingrtzhagenb FoEat Owlet Davidson's owl specimens from Khandesh fbut not those from some other localities) are all very similar and have several unusual and characteristic features that set them well apart from those of other collectors. Becausethe missing Forest Owlet is from Khandesh, we deal here with Davidson'sstyle from this locality. lt seemslikely that some of his skins were prepared by local assistantsfollowing his instructions, but for the Sgecimen fraud in Fotest Owlet 17 1 t') l () I l ( ' 5 )na) '\'cen !r65. :{3) r the lJerilort \\ ith Jrrk r oil-v nin skull |lr1cti \ ith on.-d rhort l.rnd .. the ,ncd , rhe 'n.rlly i the .l the 'LrreSt rctii-v rntcr. ,\\'let Figure 5.

Owlet,BMNH 1965.M.5220; sake of simplicity we refer herein to the Khandesh preparation style as Davidson's. The two Davidson Forest Owlets not shown in Figures 2 and 4 (the AMNH and MCZ specimens) and his other Spotted Ou'lets are very similar extemally and on X-ray view to BMNH 86.2.1.546,with no significantdifferences. :1()t :::tilr Retention of humerus X-rays of original Davidson Khandesh owls show that in 1l out of 12 cases he retained the complete humerus (Figs 4b,4c). Although the Meinertzhagen Forest Owlet now entirely lacks humeri and proximal radii and ulnae, the X-rays (e.g. Fig.4a) show the channelsin which the shaftsof the humeri lay and the impressionofthe head ofthe right humerus, indicating that the skin must have originally dried around a full sct of wing bones. 'J.'sh, l rt r . I t tJ b1 ,r the Ventral incision ,\s described above, the Meinertzhagen Forest Owlet, rrhich nou. has the ventral incision long and loosely servn with double strands of thread, must previously have had a high, sewn incision over the breast (Fig. 3b) It'rrsis .aies' tsem- and the skin over the abdomen must have first been cut duing the remaking process (Fig. 3c). Three of the four Davidson Forest Owlets have long, unservn incisions,while the 1883 specimen has a long, tightly sewn incision, so all are dissimilar to the presumed original incision o[ the Meinenzhagenspecimen on that basis. However, examination of Davidson's Spotted and Jungle Owlet specimensshowed considerable latitude in incision position and stitching: four had high, sewn incisions (as the Meinertzhagen Forest Owlet originally must have had], while ten possess other incision types. Wing-stuffing Davidson'sspecimensshow the highly unusual characteristic of having cotton stuffed around the radius and ulna without the skin over these bones having been slit (Fig. 3dJ. In all 3l Davidson owls examined for this featurE stuffing fflls the forearm vacuity rlp to near the carpal joint: this is the reason that in X-rays the skin edgesshow up well removed from the bones (Figs 4b, 4c). However, palpation and X-rays clearly reveal that none of the Meinertzhaeen Little Owls in the union,/D,q l4'1,11-21 O 1999BritishOrnilhologisls 18 PC. Rasmussen& N.J. Collal Rothschild Collection has stufftng around the radius and ulna (two examples in Fig. 5a,5b). In addition, palpation of 80 randomly selected BMNH Indian specimens(20 of each species)of Brown Hawk-Owls Ninox scutulata, hngle and Spotted Owlets, and Little Owls from various collectors showed that, of thesg only one Bourdillon Brown Hawk-Owl (1880.8.9.94, TiavancoreJ has stuffrng in the forearm, although the overall preparation style is very poor and different from that used by Davidson. When J.P.Angle slit the wing skin on the Meinertzhagen Forest Owlet for this examination, he found that while the proximal twothirds of the radius and ulna are wrapped and bound with tow, the distal portion up to the carpal joint is still stuffed with a wad of yellowed, unreffned cotton (Fig. 5dJ. In expert independent comparison of a sample of this cotton from the Meinertzhagen Forest Owlet with Gat from Ge same portion of a wing of the Davidson Jungle Owlet (collected two days after the missing Davidson Forest Owlet and at the same 'no locality) signiffcant differences were detected between these samples' (D.W Deedrick iz lin. '1997; test results on ffle with BMNH). Neck length Davidson's Khandesh owls examined are typified by their unusually long necks (Figs 4b, 4c). By contrast, Meinertzhagen's Forest Owlet has a short neck, but this is the result of the aforementioned l5-mm wide fold in the skin (Figs3a, 4a), which shortenedthe neck by at least 30 mm and probably more. In the MCZ Davidson specimen, the distance from the base of the lower mandible to the upper breast fthe neck length) is about 47 mm; in Meinertzhagen's this distance is now about 25 mm, so neck length must have been at least 55 mm in the original preparation. Position of feet and legs The feet of Davidson's Khandesh Forest and Spotted Owlets are either positioned sraight (Figs 4b, 4c), or with one leg dried off to the side, with the tarsi uncrossed. The tibiotarsi were not pushed into the body and the claws are for the most part curled in. The Meinertzhagen Forest Owlet has the feet positioned straight and close together, and the toes and claws are dried in a comparable position to those of Davidson's Khandesh bnds. The only apparent differences in leg and foot position between Davidson skins and the Meinertzhagen Forest Owlet are due to remakine: the visible portions of the legs on the Meinertzhagen bird are shorter because the skin is twisted round. Ttre skin of the right leg was largely fflled with Ornilhotogists Union, tbts,141,11-21 O'l9ggBritish cotton above the broken tarsomeerarsus. Tying ot distal humeri Davidson sometimes utilized a unique technique of 'elbows' sewing the or distal humeri together from the oztsideof the specimen, acrossthe back but under the feathers and pulled tight. Of the four attributed Davidson Forest Owlets, only the 1883 specimen has the distal humeri tied together on the outside. Examination of his other owl specimens at BMNH showed that two out of I I Spotted Owlets IBMNH 1925.12.23.951,957, from 1883J, his only Shortearcd.Owl Asio flammeus (from 1884) and two out of four Barn Owls Tyto alDa (BMNH 1925.12.23. 942-943, from 1885 and 1883, respectively) had the wings tied together from the outside. The external thread between the elbows is lacking in all ffve of his Jungle Owlets (from 1884-87), all four Brown HawkOwls (from 1895-96), his only two Tawny Owls Srni aluco biddulphi (from 1896) and his single Brown Fish-Owl Kenpa zeylnnensis(from 1883). Although tlese were previously hidden by feathers, the Meinertzhagen Forest Owlet still has pieces of matching coarsewhite thread, one sewn into the skin 'elbow' of each and lying over the back; clearly these were originally a single strand which was cut durins remaking.When positionedacrossthe back without being pulled tigh! the tlvo ends of the thread now overlap each other by about l0 mm, indicating that the wings were positioned at least that much closer together during remaking, and that they had originally been tied together on the outside in the manner typical ol and fso far as we are aware) unique to, Davidson. Of curators and techniciansin severalmajor museumswhom we have consulted, none knew of anv other preparatorwho evertied the wingsby sewingthe distal humeri together from the outside. In a random check for an external thread between the distal humeri of 100 BMNH owl specimens (Barn Owlq Brown Hawk-Owls, Short-eared Owls and Spotted Owles; 20 of each species) by several different preparators (not including Davidson), none possessedthis feature, nor did the Blewitt or Ball Forest Owlets, nor anv of the Rothschild Museum seriesof Little Owls lrom the Meinertzhagen Collection.

It is usually undertaken in the following circumstances: preparing study skins of birds as exhibit mounts or dismounting exhibit specimensfor incorporation into study skin collections; repositioning of improperly prepared specimens;cleaning of greasyor dirty skins; preparing skins that had been salted and dried in the field. However, in the case of a very rare specimen, a responsible curator would probably not sanction extensive remaking for mere cosmetic changeq since thc risk of damageis considerable;and it would seem unlikely that Meinertzhagen would have taken such a course if the specimen were already adequateor nonincriminating, Both of these circumstanceswould be e\pected to apply had the bird originally been preparedby Meinertzhagenor someoneworking under his supervision. In any case, the end result of the remaking is that the Meinertzhagen Forest Owlet specimennow bearslittle superficial resemblanceto its original preparation. Inevitably, therefore, the extensive remaking of Meinertzhagen's Forest Owlet must be regarded as highly suspicious.There are, however, severalother circumstanceswhich, independently and in conjunction, point towards the non-authenticity of \ leinertzhagen'sForest Owlet. First, his extensive unpublished diaries make no referenceto his having left Bombay during the period (i-13 October l9l4 or to his having done any collectrng at that time. The date of collection given on the specimen label, in Meinertzhagen's own hand, is 9 October 1914. The entry immediately preceding this Jate in his diary is for 6 October, and states'Sheppard and I came down to Bombay today and are staying at the Taj Mahal Hotel. We have a great deal to do now. I am busy compiling an Intelligence Book for the troops...' The following entry is for 13 October 1914, againfrom Bombay,which states'...1have been kept r ery busy here with my Intelligence work.' Second, in Meinertzhagen's own register, we can find no record of his having collected any other bird specimens at or near this time (9 October 1914) or place (Mandvi, Gujaratl. The closest register entries, both chronologically and geographically, are from Pune,between 3 September and 2 October 1914, and his diary affirms his presence there during that period but, as noted above, these apparendy genuine specimensof common roadside birds bear no r"semblance in preparation style to his Forest Owlet. Chronologically, the nearest Meinertzhagen register entries subsequentto the Forest Owlet are from East Africa, to which he sailed in late October 1914 fCocker 19901. 19 Third, our examination of contemporary maps (four miles to the inch) produced by the Survey of India Offtces, Calcutta, show that Mandvi is roughly 30 miles (50 km) eastof t}re Bombay-Baroda railway line and 8 miles (13 km) north of the Tapti Valley line that ran east through Klandesh from Surat. To fft such a trip into a maximum of six days (7-12 October), Meinertzhagen would have had to first take a ffain, then either take a secondtlain to a station near Madhi (about 2l'08'N 73'14'E) and walk/ride eight miles north, or take a boat from north of Surat up the Tapti River to Mandvi. After only a day or two at this curious destination, he would have had to make his way back again by the same means. Fourth, Meinertzhagen never himself published on the specimen, despite its rarity and obvious importance, eyen though he produced a note on other Athene (Metnertzhagen 1950). His Forest Owlet was not mentionedby Ali (1948, 19491or Ripley (1952, 196IJ, indicating that this sole Gujarat record had not yet been reported. ln Ali (1948), the only deffnite localities mentioned for the species are Phuljar (i.e. near Sambalpur) and Khandesh, although he added '... not actually met with by the Survey in that it was the Cujarat Satpuras,but of which the known distribution is suggestive'.Ali gavea signedcopy of this paper to Meinertzhagen, who stamped his library seal on it, suggestingits receipt well before his death in 1967 and probably much earlier (Meinertzhagen'shealth greatly restricted his ornithological activities after 1960: Cocker 1990), and at some stage Meinertzhagen informed Ali of his specimen ('Meinertzhagen had given me his locality as Mandvi': S. Ali in lir. to S. D. Ripley, 25 July 1975, Smithsonian Institution Archives Accession92-063). The ffrst mention of the specimen in the literature was by Ali and Ripley (1969), two years after Meinertzhagen'sdeath. Prior to that, Ripley (1952J, hence doubtless Fisher [1960) and Anon (1962), had stated that no new data had been obtained on the l.otest (Jwlet slnce ld/2. These circumstancesmake it very dif&cult to believe that a soldier who was also both a prolific collector and diarist would leave Bombay for no plausible reasonat an extremely pressing time (war having been joined only two months before); undertake a joumey that would necessarilyinvolve complicated logistics;collect only one bird specimen, by chance an extemely rare species (the only specimen recorded this century) at a locality from which it was previously unrecorded; and then return to Bombay, all without even mentioning the event in his diary or publishing on the specimen.
