I. — Descriptions of some Mammalia discovered in Cuba by 

 W. S. MacLeay, Esq. By John Edward Gray, F.R.S., 

 &c. With some account of their Habits, extracted from Mr. 

 MacLeay^s Notes. 



1 HE small collection of Mammalia made by Mr. MacLeay 

 during his stay in Cuba consisted of the following species of 

 Cheiroptera, and a foetal specimen of a Dolphin [Delphinus), 

 which I have not been able to determine on account of its 

 youth. 



The bats, besides adding to our knowledge, are very inter- 

 esting forms, and several hitherto unrecorded species are par- 

 ticularly interesting, as enabling me to locate with certainty, 

 according to my present views, the genus Mormoops of Dr. 

 Leach, of which only a single dried specimen was before 

 known, and which had always been placed among the anoma- 

 lous genera of this interesting family. It is curious, as regards 

 the geographical distribution of these animals, which have 

 usually been considered very local, that out of this small col- 

 lection of eight species five should prove to be new to science 

 and one of them an entirely new form, and that the other 

 three should be common to Cuba and Jamaica. 



Vespertilionid^e, Gray. 

 Tribe Phyllostomina, Gray. 



Arctibeus falcatus, Gray. Edge of the lips crenulated, in- 

 ner part of the sides near the angle ciUated, front of the lower 

 lip with a small central tubercle surrounded by a lunate series 

 of six distant small warts. Nose -leaf broad ovate lanceolate, 

 expanded, with a very large elevated laminar crumpled pro- 

 jected edge on the sides. Tragus thick and convex inter- 

 nally at the end, with three or four distinct notches on the 

 outer side of the ears. Fur (in spirits) grey-brown, with dark
