528 PHYLLOSTOMIDiE. 



The upper incisors form a straight line between the canines ; tho 

 central incisors are much longer than the outer ones, directed ver- 

 tically downwards, and bicuspidate, the inner cusp of each tooth 

 narrow and acute, the outer cusp broad, obtuse, and shorter (Plate 

 XXVIII. fig. 2 a) ; outer incisors very short and flat-crowned, about 

 as long as the cingulum of the canine ; lower incisors equal, deeply 

 and widely grooved in front and above ; upper molars very broad, 

 the breadth of the first upper molar equal to the conjoined antero- 

 posterior diameters of the first and second molars ; second upper 

 molar nearly equal to the first in antero-posterior diameter ; third 

 lower molar small, oval, placed transversely directly behind the ante- 

 penultimate molar, about equal in size to the base of one of the middle 

 upper incisors (Plate XXVIII. fig. 2). Palate deeply emarginate as 

 far forwards as a line joining the anterior inner margins of the first 

 upper molars of opposite sides ; sides of the emargination parallel.

Hab. Jamaica; Cuba. 



I have examined the types of A. jamaieensis, A. acJiradophilus, 

 and A. sulphweus, Gosse, which are preserved in alcohol in this 

 Collection, and I agree with Dr. Peters's statement, that they are all 

 referable to the same species. They differ only in the depth of the 

 colour of the fur, which appears to depend upon age, as the smallest 

 of four specimens, the type of A. jamaieensis, Gosse, has fur of a 

 darker shade than in any of the other three. 



Mr. Gosse remarks that this species " feeds on the fruit of the 

 Naseberry (Achras sapota). About a quarter of an hour after the 

 sun has set, and whUe the horizon is still glowing with effulgent 

 clouds, these Bats begin to fly round the tree On pick- 

 ing up the fruit find that it has been just bitten, nibbled in a 

 ragged manner. Pragments of Naseberry of considerable size, 

 partly eaten by a Bat, are frequently found at the distance of half a 

 mile from the nearest Naseberry-tree. The Eose-apple {Eugenia 

 jambos) is also a favourite fruit."*
