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

 species. Lips with vertical -wrinkles. No gular sac in male or 

 female. 



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. cestonii, except on the antebrachial 

 membrane, which is nearly naked.

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. cegyjUiacus, and by the 

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

 lower incisors. (Plate XXII. fig. 2, ear.) 



Length, head and body 2"-9, tail 1""7, tail free from membrane 

 0"-85, ear 0"-9, tragus 0"-23 x 0"-15, forearm 2", third finger 3"-6,
