Tills most distinct species presents an interesting mixture 

 of the characters of the different " subgenera " of Pseudo- 

 chirus. Clearly most nearly related to I'seudochirulus, it is 

 as large as the smaller species of Fseudochirops • it has the 

 white-ended tail said to be confined to Pseiidochirus, while its 

 brown instead of fulvous face is like Fseudochirops and not 

 Fseudocliiruhis. Its white under surface and the white 

 outer sides of its forearms are peculiar to itself. 



I have nametl it in honour of Mr. Charles B. Pratt, who 

 has taken great interost in the collecting of mammals in the 

 little-known parts of New Guinea where he and his brothers 

 have been working.

Very like F. lorentzi, as described from normal non- 

 melanistic specimens in 1912 *, the original lorentzi having 

 been based on a melanoid example. General colour less 

 rufous owing to the tips of the underfur being more bufFy 

 than rufous, but otherwise the mixture of buflfy and black 

 ticked with white is essentially similar. Under surface, how- 

 ever, very much less rufous, the rich rufous wash on the
