Two Species of Molossus. 66 



Nijctinomns brasiliensis. The geographical distinction being 

 thus done away with, and M. Temminck finding in the young 

 Molossi all the characters of the Nyctinomi has united them in 

 one. The Dinops of M. Savi, founded on a species observed 

 in Italy, there appears reason to believe is also a species of 

 Molossus, which thus proves to inhabit every quarter of the 

 old continent. 



The fact of the existence of this genus in North America, 

 and especially so far north as the United States, has not been 

 hitherto made known, or scarcely suspected. Among several 

 collections of Bats from Carolina and Georgia that have been 

 recently submitted to my inspection, I find two apparently 

 distinct, which are clearly species of Molossus, and much re- 

 lated to some of the smaller ones so well illustrated in the 

 work of M. Temminck.

Description. 



Color entirely sooty brown, darker above, paler beneath. 

 Ears with a very short rounded tragus, and remarkable for 

 being singularly and regularly crimped or fluted on their poste- 

 rior half. Numerous stout bristles about the face. Muzzle 

 broad, and lips thick and pendant, giving the ferocious expres- 

 sion characteristic of the genus. The wings long, and suffi- 

 ciently ample ; the interfemoral membrane naked, and partly 

 sustained by a slender bony process from the hind foot, the 

 tail extending half an inch beyond it. The tibia and fibula 

 short and robust, and included in the membranes their whole
