of the fore-arm bone 1 4 



The three species of this genus, in the British Museum, may be thus dis- 

 tinguished. 



A. The groove in the lower lip fringed with minute beards. 



1. Phyllophora amplexicaudata. — Nose-leaf small, as broad as high; ears 

 moderate, rounded, not as long as the head; fur brown. 



2. Phyllophora nigra. — Nose-leaf ovate-lanceolate, longer than broad ; ears 

 moderate, rounded, not half as long as the head. 



B. The groove of the lower lip simple, not fringed on the edge. 



3. Phyllophora megalotis. — Nose-leaf large, ovate-lanceolate, longer than 

 broad ; ears very large, as long as the head. 



Leach's Monophylle. — Monophyllus Leachii. 



Dusky brown ; under-side rather paler. Tail half as long as the width of the interfemoral 

 membrane. Nose-leaf elongate, ovate-lanceolate. 



Inhab. Central America, Realejo. 



In. Lin. 



Length of the body and head 1 5 



fore-arm bone 1 4- 



heel bone 2 



This species differs from 31. Redmanni of Leach {Lin. Trans, xiii. 76.) 

 in being much smaller, and in having the interfemoral membrane wider, the 

 tail shorter, and the nose-leaf longer than in that species.
