TWO UNDESCRIBED WEST INDIAN BATS. 

 BY GLOVER M. ALLEN. 



Zoological explorations undertaken by the Museum of Com- 

 parative Zoology in recent years have greatly enriched its collec- 

 tion of West Indian bats and provided adequate material for a 

 comparative study of sundry species which are represented in 

 several of the islands by slightly differentiated races. Two of 

 these latter are here described and named. The first is an 

 Erophylla, one of the subfamily Phyllonycterinae, from the 

 island of Jamaica, where it had not been previously reported; 

 the second is a race of the large Chilonycteris parnelli from Santo 

 Domingo, an island whence the species was likewise previously 

 unrecorded. These two records now establish the presence of 

 both Erophylla and the large Chilonycteris on all four of the 

 Greater Antillean islands. The former is also represented in 

 the Bahama group. The chief point of interest is that the 

 Jamaican and Cuban forms of each species are closely similar to 

 each other, and the Porto Rican and Santo Domingan repre- 

 sentatives likewise are very similar to each other, but the races 

 from the first two islands differ much less from each other than 

 they do from their congeners on the other two islands. 



The genus Erophylla is apparently confined to the Greater 

 Antilles, where it has hitherto been known from Cuba {E. seze- 

 korni), the Bahamas (E. planifrons) , Santo Domingo (E. santa- 

 cristobalensis) , and Porto Rico (E. bombifrons). Its presence in 

 Jamaica, though to be expected, had not been confirmed until 

 1912, when Dr. Joseph A. Cushman captured a small series at 

 Montego Bay. These specimens, which are now for the first 

 time recorded, I have compared carefully with the other known
