Bah. S.E. New Guinea (Sogere). 



Type in collection. 



This very handsome species, the smallest of the genus, is the only 

 one that has as yet been discovered anywhere in New Guinea except 

 in the north-west. While agreeing very closely with Ps. eanescens 

 in many of its characters, and forming, with that species and Ps. 

 schlegeli, a very well-defined section of the genus, it yet differs 

 remarkably from all in the total suppression of its posterior incisors 

 and anterior premolars. Most unfortunately, the second specimen 

 received from Mr. Forbes (specimen 6) has had its head entirely 

 destroyed by shot, and therefore no information can be gained from 

 it as to the constancy with which these teeth are absent in the 

 species.
