M. C. COOKE ON THE HAIRS OF INDIAN BATS. 57 



supposed spiral arrangement of the scales in Bat-hair, as alluded to by dif- 

 ferent -vn-iters, probably originated in the deceptive appearance caused by 

 these 'sugar-paper scales.' 



15.— Rhinolopuus perniger. Hodgs. — ' Sikkim Horse-shoe Bat.'— Nepal, 

 Sikkim, &c.— Hairs translucent, with rather irregularly serrated outline ; 

 large hairs with cylindrical expanding scales, the margin irregular, often 

 oblique; smaller hairs irregular, scales more expanded upwards, with 

 oblique margin.— ('J'?. I, fig. 13.^ 



16.— Rhixolophus morio. C'my.- Singapore. — Not examined. 



17. — Rhinolophus mitratus. Blyth.—G&Q.ix2k\ India.— Hairs not ex- 

 amined. 



18.— Rhinolophus Pearsoni. ^ors/".- (Pearson's ' Horse-shoe Bat.')— 

 Sikkim Himalayas.— The length of this bat to the root of the tail is three inches, 

 and the tail half an inch ; expanse of wing eleven inches ; the colour above 

 is dark brown, with a slight shade of chesnut, underneath brown, with a sooty 

 cast ; the fur is very long, dense, and soft. Large hairs translucent ; scales 

 cylindrical, irregular, close together ; small hairs irregular, with an angu- 

 larly waved outline ; scales expanding upwards with oblique margin. — (PI. 

 2, fig. 14 large hair, fig. 15 small hair.) 



19.— Rhinolophus brevitarsus. jBZy^A.— Sikkim.— This species I have 

 not seen. 



20. — RHINOLOPH0S tragatus. ^(?<?^s.— ('Nepal Horse-shoe Bat.') — 

 Himalayas.— Both kinds of hair very similar to those of Rhinolophus 

 Pearsoni, and scarcely to be distinguished therefrom, except that the smaller 

 hairs have a less waved and angular outline.— (P?. 2, fig. 16 large hair, fig 17 

 small hair, in two positions.) 



21, — Rhixolophus ajtinis. ^or^/l-C Malayan Horse-shoe Bat.') — 

 Malay countries, &c.-^Large hairs of the same type as in the species above 

 described ; small hairs more irregular in outline and angular than in the 

 last ; margins of the scales scarcely so oblique. — (Small hair, PI. 2, fig, 

 IS.) 



22.— Rhinolophus Rouxi. Tcmm.—(' Bengal Horse-shoe Bat').— Bengal, 

 &c. — Large hairs with the margins of the scales more or less oblique ; small 

 hairs straight, usually regular in outline, slender, with attenuated scales of 

 the ' sugar-paper ' type, resembling those of Rhiiwlojjhns tragatus, but 

 longer, and slightly darker and more striate in balsam. — (Large hair, PI. 2, 

 fig. 19.; 



23. — Rhinolophus minor. Horsf. — (' Little Horse-shoe Bat.') — Java. — 

 Is apparently only a variety of the above. — (PI. 2, fjg- 20, large hair.) 



24. — Rhinolophus sub-badius. Hodgs, Nepal. — Character of the hair 

 unknown. 



25. — Rhinolophus macrotis. Hodgs, Himalayas. — Hair not ex- 

 amined. 



26. — Hipposideros akmiger. .Sb<7^s.— ('Hodgson's Horse-shoe Bat.') 

 Himalayas. — All the hairs larger than in the majority of species in this 

 genus ; large hairs scarcely serrate at the edge ; scales irregular, margin 

 often oblique ; small hairs cylindrical, expanded, with oblique margins as in
