60 M, C, COOKE ON THE HAIRS OF INDIAN BATS. 



of uniform length throughout. {Horsfield.) The hairs are translucent, 

 with an acutely sen-ated outline ; the scales are cylindrical, expanding up- 

 wards, rather distant, with a toothed margin ; the hairs are transparent, and 

 of a lighter tint than those of either species of Ehinopoma or Taphozous — 

 (PL 2, Jig. 34.; 



48.— Topping's Indian Bat (Species unknown.— (Hairs rather opaque, 

 dark coloured, with a very deeply serrated outline ; scales trumpet- shaped, 

 expanding at the margin to nearly three times the diameter of the shaft 

 (fig. 61 a.); margin with numerous acute teeth, — (PI. 2, fig. 35 .J 



49. — Australian Bat. (Species unknown.)— Hairs rather opaque, dark 

 coloured, with a deeply notched outline ; scales broadly cup-shaped ; more 

 than three times the diameter of the shaft ; margin with numerous teeth. —

GROUP V. 



50.— NocTULiNiA Malaccensis. Gray. — Singapore.— Hair not ex- 

 amined. 



51.— Noctulinia noctula. Bell. — (' Himalayas') — Europe.— Hair not 

 examined. 



62.— Ntcticejus oenatxjs. Blyth. — (' Blyth's Nycticejus.')— Himalayas. 



Hairs semi-transparent, with slightly serrated outline ; scales indistinct, 

 seldom wholly surrounding the shaft ; margins usually more or less oblique. 

 Hairs of all the species of this genus very transparent in balsam, and the 

 scales apparently imbricated.^('PZ. 2, fig. 39.J 



53.— Nycticejus Heathii. Hor«f. Southern India.— Hair not ex- 

 amined. 



54.— Ntcticejus luteus. Blyth. — (N.flaveolus'&i.., Yellow Nycticejus.) 

 Bengal, &c. — The colour varies considerably in different individuals, being 

 dark -brown above, in different shades, and rufous or yellowish underneath. 

 (Horsfield.) Hairs similar in all the species, scarcely to be iistinguished 

 from each other ; the scales of the haii's in this species are usually alter- 

 nate, only half surrounding the shaft. — (PI. 2, fig. 40.; 



55.— Nycticejus Temmenckii. i?brs/'.—('Temminck's Nycticejus.')— India 

 and Malay countries. — A peculiar character is afforded to this species by the 

 shortness of its fur ; the colour is pure dark brown above, grayish brown, 

 somewhat dusky underneath, with a rufous tint {Horsfield) ; hairs semi- 

 transparent, slightly serrated ; scales sometimes encircling the shaft, and at 

 others only partially. The hairs of this, and also of the preceding, demand 

 further and more complete examination. — (PI. 2, fig. 41.; 



56.— Nycticejus castaneus. Gray — (' Chestnut Nycticejus.').— Malay 

 countries ; Bengal. — The characteristic feature of this species. Dr. Horsfield 

 says, is the uniform deep chestnut colour of the body above and beneath ; 

 the hairs are semi-transparent under the microscope, with but slightly 

 serrated margins ; the scales appear to be usually cylinth-ical, with irregular 

 margins, but sometimes only partially surround the shaft. — (PI. 2, fig. 43.; 



57.— Nycticejus Tickelli. Blyth.— (N. isalellims Bl.,— Central India.) 

 — Hair not examined.
