fourth of the tibia ; calcaneum none ; tail very short, projecting by 

 its last vertebra beyond the narrow interfemoral membrane. 



Pur, above, light brownish yellow, paler on the neck and on the 

 sides of the body, the base of the hairs and their extreme tips 

 whitish ; beneath, paler. 



Teeth very similar to those of CarolUa hrevicauda ; the hinder 

 upper molar is proportionally larger, and the lower incisors axe equal 

 in size.

About the size of Ph. poeyi, and resembling that species closely in 

 general structure and in the colour of the fur. It is distinguished 

 by the different form of the nose-leaf, which terminates behind in a 

 small pointed process, and by the presence of a small calcaneum, to 

 which the narrow interfemoral membrane extends backwards along 

 the leg.

Hob. Cuba; Jamaica*. 



Mr. Osbuxn, in notes on recently-killed specimens of this species, 

 remarks (P. Z. S. 1865, p. 82) that the tongue narrows towards the 

 tip more suddenly than in MonophyUus redmani, and that it is 

 covered with reversed prickles, which are especially long and bristle- 

 like on the edges of the tip. 



A colony of this species, consisting of a great number of indi- 

 viduals, was discovered by Mr. Osbum in a cave near TrelavsTiy, in 

 Jamaica. The visit to the cave was made in the month of June, and 

 the number of the sexes was found pretty equal. Most of the 

 females had young, but in no case was more than one young one 

 found with a single female. The floor of the cave was found 



* The types oi Ph7/llon^cteris poet/i an A Fh. sezekorni have not been examined 

 by me. I am therefore obliged to foUow the original descriptions by Dr. Guud- 

 lach, who, although noting such an important diiference as the absence of the 

 calcanea, yet appears doubtful whether P^. sezekorni should really be considered 

 a distinct species. It is certainly strange that such a remarkable structural 

 difference should exist between two forms otherwise so very closely allied 

 and inhabiting the same locaUtieg, and it seems very probable that the ap- 

 parent absence of the calcaneum in the type of Ph. poeyi is the result of in- 

 different preservation. In two skulls sent by Mr. Osburn from Jamaica there 

 are very slender flbro-cartilaginous zygomatic arches.
