then changing abruptly to white, the white corresponding in 

 length to the part which is naked below. 



Skull larger than in larvatus, but of similar form. Nasals 

 widely expanded behind. Interorbital region narrow, with 

 the usual parallel rounded ridges. Posterior part of bulUe 

 unusually swollen^ projecting nearly as far backward as the 

 condyles do. 



Teeth with the usual well-marked diastemata characteristic 

 of the group. Molariform teeth narrow.

This most distinct species presents an interesting mixture 

 of the characters of the different '' subgenera " of Pseiuio- 

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

 as large as the smaller species of Pseudochirops ; it has the 

 white-ended tail said to be conHned to Pseudochirus, while its 

 brown instead of fulvous face is like Pseudochirops and not 

 PseudocJiirufus. Its white under surface and the white 

 outer sides of its forearms are peculiar to itself. 



I have named 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. 



Phascogale lorentzi venusta, subsp. n. 



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

 melanistic specimens in 1912 *, the original lorentzi having 

 been based on a nielanoid example. General colour less 

 rufous owing to the tips of the underfur being more bufty 

 than rufous, but otherwise the mixture of bufFy and black 

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

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