Mr. Miller (1902, p. 410) has recorded the finding of remains of 

 this species in the pellets of the Cuban barn owl, which shows that 

 it is occasionally captured by that bird.

This race, described from the island of Trinidad, is recorded by 

 Andersen (1908, p. 279) from St. Vincent only, of the West Indies. 

 Its occurrence should be expected probably on the intermediate 

 islands, and on Tobago as indicated by this author.

Andersen has named this race on the basis of three specimens from 

 Dominica and Guadeloupe. The type is from the latter island, and 

 represents a form a very little smaller than A. j. palmarum, of which 

 it is considered a northern offshoot. Its similarity to A. j. aequa- 

 torialis of Ecuador and southern Colombia is so great that the two are 

 indistinguishable, a fact which Andersen believes is due to parallelism 

 in development.

A series of forty specimens was obtained in 1910 at St. George's, 

 Grenada, from the recesses of an old fort on Richmond Hill. Here 

 was evidently a breeding colony; and as usual among bats of this 

 genus, the adults were mainly of one sex, for, of the thirty adults, 

 all but four were females. The breeding season was apparently over, 

 for all but one of the young obtained were well grown. The single 

 exception was still suckling, and of about half the bulk of its mother. 



Dr. Knud Andersen (1908, p. 204-319) has shown that the bats of 

 the planirostris group have spread from the mainland of South America 

 to the southernmost of the Lesser Antilles, and in Trinidad and Tobago
