EEPORT ON THE MAMMALS. 



OEDER 



CHEIROPTERA. 



Family ISTIOPHORA. Leaf-Nose Bats. 



r 



Ch, — Molars cuspidate ; nose with a foliaceous or leaf-like appendage, in which the nostrils are situated. 



The leaf-nosed "bats are easily recognized among tlie other Cheiroptera by the presence of a 

 peculiar appendage to the nose. This, instead of being simple, with two nostrils opening at 

 the end or sides of the muzzle, as in ordinary mammals, is provided with a peculiar appendage 

 of varied form attached to the extremity of the snout, and having the nostrils opening through 

 it. There are four sub-families of the group, which may be characterized as follows : 



r 



a. Desmodina. — Molars presenting a longitudinal sharp edge, and of the minimum number, (5^33 ). Nasal appendix without 



r 



any upright leaf; the ears separated ; a triangular bald spot on the end of the lower lip. Anal membrane short or none ; tail 

 wanting. 



The species confined to South America. 



b. Phyllostomata. — Molars cuspidate; ears separated; nasal leaf lanceolate, erect, (except in Brachyphyllum.) Inter- 

 femoral membrane short ; deeply excised ; tail very short. 



Of this group one species, Choeronycteris mexicana^ is found in Mexico. All the others belong 

 to South America. The assignment of a species, Brachypliyllum cavernarum^ to South Carolina, 

 as well as the West Indies^ has not been substantiated by any American author. 



c. Megadermata. — Ears large, united ; tragus present. 



It is in this group that the species I propose hereafter to describe is found. 



d. Rhinolophina. — Ears large, separated ; without a tragus. 



The species of this group are confined to the Old World. 



MACROTUS, Gray. 



MacTotuSy Gray, Voyage of the Sulphur, 

 Gen, Ch. — Nasal appendage with the leaf ovate, lanceolate, erect ; inter-femoral membrane large ; tail long; free at the tip. 



It is to the genus Macrotus of the sub- family Megadermata that the first leaf-nosed bat 

 ever positively known as an inhabitant of the United States belongs.' It is true that the 



Brachyphyllum cavernarum of the Phyllostomata has been given as occurring in South Carolina, 

 but the statement has never been verified by any of the large corps of excellent naturalists 

 resident in that State, and is probably an error.
