 (1835-41); Wagner, Suppl. Schreb. Saugeth. i. p. 469 (1844). 



Much smaller tban N. africanus. Ears quite separate, but close 

 together by the bases of their inner margins ; outer and inner mar- 

 gins of the ear-conch evenly convex, forming almost an arc of a circle 

 above ; antitragus half-oval, separated by a deep notch posteriorly ; 

 tragus broad and rounded off above as in the preceding species. 

 Lips with vertical wrinkles. 



Wing-membrane from the lower part of the tibiae, near the ankles. 



Fur, deep smoke-brown above, paler beneath. Distribution of 

 hair on the membranes as in N. cestoni, except on the antebrachial 

 membrane, which is nearly naked. 



Length (of the type, an adult J specimen preserved in alcohol) : 

 head and body 2""6 ; tail 1"6, tail free from membrane 0" - 9 ; head 

 0"-95; ear 0"-9, tragus 0"-23xU"- 15 ; forearm l"'95 ; thumb 0"-28 ; 

 second finger — metacarp. 1"*9, 1st ph. 0"-"5, 2nd ph. 0" - 8; third

4. Nyctinomus tragatus. 



Nyctinomus tragatus, Dobson, J. A. S. B. 18/4, p. 143, Mono- 

 graph Asiatic Chiroptera, p. 181 (18/6) 



This species resembles N. cegyptiacus very closely, but is larger, 

 and has always six lower incisors. That this is not due to age (as 

 the young have generally six lower incisors, even in species in which 

 four is the normal number in the adult animal) is shown by the 

 relative measurements of this species and N. cegyptiacus, and by the 

 presence in every specimen (as yet examined) of this species of six 

 lower incisors. 



Length : head and body 2" - 9 ; tail l" 1 /, tail free from membrane 

 0"*85 ; ear 0""9, tragus 0' ,- 23 X 0""15 : forearm 2""0 ; second finger 

 3"-6 ; fourth finger 1""9 ; tibia 0"-6 ; foot and claws 0"-35. 



Hab. Peninsula of India (Rajanpur, N.W. frontier; Jashpur near
