96 Allen Mammals of Margarita Island. 



narrower than that of P. canina. It differs notably from both in having 

 the first premolar in contact with the second premolar on the one side 

 and the canine on the other, instead of separate from both, as in the 

 two other species. There are also other minor differences, and the den 

 tition throughout is rather heavier than in the other two forms men 

 tioned. 



10. Molossus obscurus E. Geoffrey. Dusky Molossus. 



Three specimens were obtained by Mr. Clark, one of which, a young 

 one and nearly naked, was found scrambling about on the roof of a house 

 at El Valle, July 14th. The two adult examples were shot July 11, 1901, 

 as they were hanging in a cave under a large rock. They show some 

 slight individual variation, the male being the larger, and the fur a 

 dark sooty color, with the bases of the hairs nearly white. The female 

 is brighter, with a brownish cast, and the bases of the hairs a light fawn. 

 Mr. Gerrit S. Miller, Jr., who also examined these specimens, writes 

 that they are not referable to M. pygmceus of Curacao, but appear to be 

 obscurus as now understood. 



ii. Micronycteris megalotis (Gray). Common Long-eared Bat. 



This species is probably common on the island. Capt. Robinson men 

 tions taking a pair on July 12, 1895, at El Valle, from a slight hollow 

 under a boulder. Two were secured in the large cave already men 

 tioned, on July*13, 1901, by Mr. Clark. 



12. Qlossophaga soricina (Pallas). Shrew-like Glossophaga. 



Two specimens of a Glossophaga obtained by Mr. Clark are referable 

 to this species as at present understood. One is an adult male, and the 

 other a young individual, still possessing its milk teeth. Both were shot 

 July 13, 1901, in the large cave on one of the hills back of El Valle. A 

 third specimen of Glossophaga, an adult female, was obtained in this 

 cave on the same date, and though somewhat battered, seems rather 

 distinct from the specimens of G. soricina, and may represen an unde- 

 scribed species. Further material is necessary, however, to determine 

 this point. It differs from G. soricina most notably, in the possession of 

 a larger nose-leaf, a slightly longer, higher and broader skull, and in 

 having the 1st and 2nd upper incisors separate from each other and the 

 canines instead of touching, as in G. soricina. There are also a few other 

 minor differences. The specimen is of a dull chestnut or tawny-brown, 

 a color which I have not observed in the specimens of G. soricina ex 

 amined.
