﻿VESPERTILIO FUSCUS BAHAMENSIS. 



101 



General remarls. — Among the races of YespertiUo fiiseus, V. fuseiis 

 2))'opinquus differs most widely in size and in form of head from its 

 nearest geographical ally, Y. fuscus mlradorensis. It combines the 

 small size of the West Indian haliamensis^ the broad muzzle of true 

 fuscus, and the delicate ears and membranes of the southern races in 

 general. Additional material may show that it is specifically distinct.

of muzzle less than half length of head: ears narrower than \\\ propin- 

 rpms, about as in typical 



Ears. — Ears smaller than in typical fuscns, but of essentially the 

 same shape, thus narrower than in propinquus. The ear membrane is 

 thinner and more membranaceous than in true fuscus. in this respect 

 resembling that of the other southern races. 



Membranes and feet. — The membranes and feet are as in typical 

 fuscus, allowance being made for the smaller size of hahamensis, and 

 the difference in texture of the membranes common to all the southern 

 races. 



Fur and color. — The fur is shorter than in true fuscus, averaging only 

 about 8 mm. in length on the back. It is distributed exactly as in the 

 typical subspecies. So far as caii be determined from specimens pre- 

 served in alcohol, the color is considerably darker and duller than in 

 true fuscus.
