Pteropus edulis, v. Edwardsii y &c. 



Pt. Leschenaultii, Desm., v. Pt. seminudus, Kelaart. A fine 

 pair in spirit, a skin, and specimen now prepared as a skeleton. 



Cynopterus marginatus, (B. Ham.) Some ordinary brown 

 examples in spirit, and a skin with the neck and sides of a very deep 

 ferruginous hue, in which phase this species is the C. Horsfieldii of 

 Mr. Gray. In old Bengal specimens, the same parts become deeply 

 tinged with bright tawney or rufo-fulvous, but are never dark ferru- 

 ginous, so far as we have seen.* Malayan examples are of a paler 

 and more uniform brown, and constitute the C. titthcecheilus, (Tern.), 

 &c. &c. if exhibiting no further difference whatever that we can per- 

 ceive, notwithstanding the remarks of Dr. Horsfield in his recently 

 published catalogue of the specimens of mammalia in the Hon'ble 

 Company's Museum in London. 



Nycticejus Temminckii, (Horsfield, nee Ruppell, Atlas), v. Be- 

 langeri, castanea, et noctulinia, auct. Two specimens, one paler than 

 the other on the upper parts. By exposure to the light, the fur of 

 this species fades and becomes much more rufous or rufo-fulvous ; and 

 in all Indian specimens that we have seen, the under-parts are con- 

 stantly much paler than the upper : but in one Javanese example in 

 the Society's collection, the upper- parts are of a much more vivid 

 tawny-rufous or ferruginous colour than we have seen in any Indian 

 specimen, and the under-parts are scarcely fainter in hue. We consi- 

 der this to be a casual variety only, analogous to those of certain 

 Horse-shoe and various other Bats mentioned in the sequel.^ N» B. 

 Although in the recent state, this very common Indian species is most 

 easy to distinguish from N. luteus, nobis (J. A. S. XX, 157), from 

 the considerable difference of colour, however either may vary, they 

 both fade and alter so much in colour by exposure to light that they 

 then appear like larger and smaller races of the same species, — the 

 under-parts of M. luteus, however, becoming generally of a more 



* Since writing the above, we have obtained a fresh Calcutta specimen, which 

 at first was very nearly as deeply tinged with ferruginous as the example from 

 Ceylon ; but, in drying, the colour has faded very considerably.
