Type in the Sydney Museum. 



This species presents much the same external resemblance to 

 Dorcopsis luctuosa that M. brunii does to D. mulleri. It may, how- 

 ever, be easily distinguished, as in the other case, by its shorter 

 head and by the direction of its nape-hairs. The " M. jvJcesi," 

 "IM. gracilis," and "If. tibol" of Miklouho-Maclay are apparently, so 

 far as can be made out from the very insufficient description of them, 

 all based on variously aged specimens of this species, so that its 

 range extends over a much wider area than has hitherto been re- 

 corded. The skull 'of " M. juJcesi," figured by Maclay, exactly 

 matches that of the type of M. lugens (specimen a below), so that 

 its degree of immaturity can be easily gauged.
