Nyctinomus pumilus, Dobson, P. Z. S. 1876, p. 723. 



Ears shorter than the head, united upon the muzzle (as in the 

 preceding species), but by a deeper band ; outer and inner margins 

 of the ear-conch continuous, evenly roimded above, the inner mar- 

 gin with three minute horny points ; antitragus half-oval, arising 

 abruptly from a point behind and on the same level with the angle 

 of the mouth, directly below the posterior commissure of the eye- 

 lids, separated posteriorly by a narrow moderately deep notch ; 

 tragus small, quadrate, superior margin straight, parallel to the 

 base of the tragus ; keel of the ear-conch small, straight, not ex- 

 panded in lower third ; extremity of the muzzle not projecting as 

 much as in the preceding species, the distance from the anterior 

 margin of the nostril to the margin of the upper lip not ex- 

 ceeding the length of the base of the antitragus ; upper lip very 

 expansible, with deep vertical wrinkles. No gular sac in male or 

 female. 



Wings from the distal third of the tibia. 



Pur rather short, but longer than in the preceding species ; above, 

 whitish at the base, then dark brown to the tips of the hairs ; be- 

 neath, less white at the base of the hairs, but slightly greyish at 

 the tips. 



Distribution of the fur upon the wing-membrane as in N. cestonii ; 

 a narrow band of short hairs behind the anterior two thirds of the 

 forearm on the upper surface. 



In the male a thick tuft of long hairs arises from the back of the 

 deep band connecting the ears ; in the female this hair is not longer 

 than on the adjoining inner sides of the backs of the ears.
