in Cuba by W. S. MacLeay. 3 



Tribe Noctilionina. 



* Tail short, tip free on the upper side of the truncated in- 

 terfemoral membrane. 



Mormoops, Leach, not F. Cuvier. Nose obliquely trun- 

 cated, warty ; lower lip expanded, membranaceous, sinuous, 

 with a square warty plate in front ; ears large, united over the 

 forehead, with the lower edge produced and united to the 

 membranes on the lower lip. Tragus distinct. 



Dr. Leach, who first described this genus, characterizes it 

 as having " a single nose-leaf confluent with the ears," and 

 all subsequent writers, misled by his description, have placed 

 it with the Zeo/'-nosed bats. In my new arrangement I placed 

 it at the end of the Phyllostomina, with a mark of doubt before 

 it. The specimen under examination shows that it has no 

 true nose-leaf, but that it is much more closely allied to the 

 Taphozoi among the Noctilionina. This and the new Cuban 

 genus Chilonycteris, which agrees with it in many particulars, 

 will together form a new section in that group, characterized 

 by the expansion of the lower lip and the convex and rounded 

 form of the skull.

The Cuban specimen agrees well with Dr. Leach's short 

 description and the detailed figure of the head of the specimen 

 which was formerly in Mr. Brookes's museum, and which he 

 received from (Mr. Lewis) Jamaica : the only difference that I 

 can see between them is that the two appendages in front of 

 the disk in the centre of the chin are rather larger in the figure 

 than in our specimen, and the hinder fold of the hinder mem- 

 branes in front of the chin is represented as entire instead 

 of being divided ; but these I am inclined to regard as most 

 probably errors of the artist, arising from Dr. Leach's speci- 

 men being dry, while ours is preserved in spirits. 



As Dr. Leach's description was very short I shall now pro- 

 ceed to give a more detailed account of this curious and very 

 interesting animal. The head is nearly globular, with a rather 

 produced muzzle. The nose is rounded above, with three 

 warts on each side, and obliquely truncated below, with a lon- 

 gitudinal central rib and a dentated transverse rib between the 

 margin and nostrils. The upper lip is flat, expanded, with
