82 ZOOLOGY. 



This sreims belongs to the molossoid group of the family, hut is :.i 



once distinguished from the large American genus Mollossus by having 2—2 



instead of 1-1 upper premolars; furrowed instead of smooth lips; well 



developed tragus instead of a mere point of integument; large joined ears 



instead of moderate separate ones, etc. We have a single species of the 



genus, which is extensively distributed, not only in America, but in Africa 



and Australia.

Chars. — To the generic characters already given may be added : Fur thick, short, 

 and soft, above dark fawn with whitish bases of the hairs, below delicate fawn with 

 ashy bases. It is almost entirely confined to the body, but extends one-third way up 

 tin- back of the cars, and forms an interbrachial patch on the wing-membrane. 

 Length, 3}-3j|; expanse, 10-11; tail alone, 1-1}; fore-arm, 1$ ; shin, A ; longest linger, 

 .'! : car, about A. 



Hab. — Tropical and warm temperate America from the Southern United States 

 to Chili and Buenos Ayres. 



This is a widely distributed species, which, as seen by the above 

 synonymy, has been redescribed under a variety of names, generic and 

 specific, all of which, however, only refer to a single animal. In this 

 country, it is ascertained to occur from South Carolina to* Texas and in 

 California. It also inhabits Mexico, the West Indies, Central America, and 

 various parts of South America. Its peculiar physiognomy, only less sin- 

 gular than that of the Leaf-nosed Bat, renders it unmistakable.
