5. DOEcopsis. 87 



anterior transverse ledge narrow and not extending to the inner 

 side of the tooth. Premolar and molar series of the two sides 

 nearly or quite parallel, instead of being more or less convergent 

 before and behind. 



Sange. New Guinea only. 



This genus forms with the next, as Prof. Garrod has shown, a 

 small separate group, whose distinguishing characters, however, do 

 not seem to be quite so constant as that author supposed, especially 

 as the recent discovery of D. madeayi provides a link between 

 Dorcopsis and Macropus.

* This name having been given under an entire misapprehension, and the 

 species being distmctly not the " Kangaroo of the ancients, ' by which is meant 

 the " Jilander" of De Bruyn, i. e. Macroptts brunii, it is evident that the specific 

 name of veterum has no claim to adoption.
