8 NORTH AMERICAN EATS. 



Description. — Head rather large ; made to appear more so by 

 the heavy pendulous lips. Ears broad as high, obtusely square, 

 almost joiuiug on top of the head ; on their inner anterior border 

 five minute warts are observed. The outer border is emargiuate 

 at its upper, strongly concave at its lower portion, where at its 

 basal third it is doubled upon itself. The mouth has upon it a 

 bristled wart. The tragus is small, very obtuse ; the outer border 

 rather the longer. It is furnished at the tip with three or four 

 bristles. The sides of the face are very little swollen. The in- 

 flated portions are continuous with the inner border of the ear, 

 and both it and the pendulous lips, which are crimped into eight 

 perpendicular lines, are studded with stiff bristles some three lines 

 in length, those near the mouth being shorter. The snout is pro- 

 minent, produced, truncated, and emarginate ; a little ridge runs 

 down the median line. The upper margin is beautifully crenu- 

 lated, the lower is thickly set with a row of projecting setae, 

 between which and the base of the nostrils runs a deep groove. 

 The nostrils themselves are simple, rounded, and open sublaterally. 

 The lower lips are thick but not crimped ; they are quite bristly, 

 and a small median wart is placed three lines from the mouth. 



The fur is thick, short, soft, and almost entirely confined to the 

 body. Above it is dark fawn at tip, with a base of a whitish hue. 

 It extends up upon the back of the ears one-third their height. 

 There is a very delicate patch on the interbrachial membrane. 

 In front the color is light cinereus at base ; tip a delicate fawn. 

 Thumb moderate. Foot large ; toes furnished with long hairs ; the 

 first and fifth fingers with numerous and thicker hairs in addition. 



Nyctinomus nasutus, Tomes, has been selected as the name of 

 this species after careful search. For a long time, N. hra- 

 siliensis, Is'd. Geof., was thought to have the priority, but the 

 reference following Dysopes nasutus, Spix, in the above synonymy, 

 shows clearly that this description has the priority of one year 

 over the former. Mr. Tomes's name follows the title, since he 

 was the first to give it its proper name. 



Geoff. St. Hilaire, after founding the genus Nyctinomus, is said 

 to have described a bat from North America, which was called 

 Rhinopoma carolinensis. This is considered by Major Leconte 

 to be the same as the species under consideration. But Nycti- 

 nomus has a naked nose, while Rhinopoma has a well developed 

 noseleaf and operculum. There has been no figure given of this
