82 ZOOLOGY. 



This genus belongs to the molossoid group of the family, but is ;ii 

 once distinguished from the large American genus MoUossus by having '11 

 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.

CHAKS. 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 

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

 Length, 3^-3=*; expanse, 10-11; tail alone, 1-1 J; fore-arm, 1 ; shin, i ; longest finger, 

 3; ear, 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 abovo 

 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 oi' South America. Its peculiar physiognomy, only less sin- 

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