San Fernando was given in 1866 by Prof. Peters, § and these ai'e 

 also for the most part the first records of the species in the 

 island. As will be seen by the present list the exertions of our 

 President, Mr. Caracciolo, and of .Mr Hart have increased the 

 number of bats to 27. but this is certainly not more than a half, 

 and possibly not more than a c^uarter or a fifth of the species 

 which actually o^cur. 



Frimates— IVIoiili:ej'~s. 



There appear to bo only two species of Monkey ia Trinidad, bnt as 

 alrettdy noted the proper scientific name of neither of them is certainly 

 known; skins of wild killed specimens are, therefore, particularly wauted. 

 Enqniries should also be made as to the presence of Marmoset.' or other 

 Monkeys in the forests of the interior. 



1. Mycetes sp. (probably 3/. seniculus) the Howler. 

 SiMiA SENICULUS, Ledru. 



Mycetes BARBATUS, de Verteuil. First record in Trinidad 

 —Ledru, 1810. 



2. Cebus sp. First record-— de Verteuil. Capuchin monkey. 



Cliiroptera — Bats. 



The Bats of Trinidad form the greater part of its Mammalian Fauna, 

 and the number of them here given will no doubt be largely increased in 

 the future. It would be of great interest if observers would try and find 

 out if there is any migration of bats between Trinidad and the 

 Mainland according to season, a migration which is known elsewhere, and 

 is Bupposed to be induced by the different times of the ripening of different 

 sorts of fruit, the presence or absence of insects, and similar causes. 

 Specimens of each species should be obtained if possible at different times 

 of the year to prove their presence at the various seasons. 



FAMILY VESPERTILIONIDJE. 



Of the Vespertilionine group of bats, to which the majority of the 

 European bats belong, only two have as yet, been found iu the Island, 

 although some half dozen more might be expected to occur there. These 

 bats are distinguished by having no exfoliations or " nose leaves " on the 

 muzzle, and by having their tail contained in the interfemoral membrane, 

 and continued just to iti hinder edge, the tip alone projecting. The Trinidad 

 species are : — 



3. Vespehtilio nigricans, Wied. Vespertilio parvulu$, 



Teram. Peters. First discovery in Trinidad — Dr. 

 Huggins. 



4. Thyroptera tricolor, Spix. First discovery — Mr. 



Caracciolo, Jan. 1893.
