Phlceomys WATERH. Ears moderate, haiiy. Bristles very long. 

 Fore feet tetradactylous with hallucar wart, with nail flat ; hind feet 

 pentadactylous. Claws compressed, incurved, large. Tail shorter 

 than body. 



Sp. Phlceomys Cumingi WATERHOUSE, Proceed, of the Zool. Soc. vn. 1839, 

 pp. 107, 108; from the Philippine Islands; a large species, blackish-brown, 

 with a red tint on the back; tail black; length 19", tail 13" or 14". Its 

 external air withdraws this species from the genus M us, with which, how- 

 ever, it agrees in the teeth (which I have not been able myself to examine).
