tliumb, and in many specimens a faintly indicated tuft near proximal 

 end of forearm. On tbe ventral surface tlie fur barely reaches the 

 uropatagium except along the basal fourth of tail. A thin coating of 

 fur occupies the under side of the wing membrane to a line joining 

 elbow and knee. Beyond this it extends in a strip about 10 mm. wide 

 along posterior edge of forearm to bases of lingers. The greater part 

 of the propatagium is thinly furred. 



Color light yellowish brown of variable shade, the hairs throughout 

 the body with narrow dark plumbeous bases and those of the back 

 with faintly dusky tips. The general effect is suggestive of the color 

 of Fipistrellus subfla vus.
