Ols. Of this species Prof. Owen remarks — “ "With a certain increase of size 
of both mandible and molar teeth, represents the form and size of the ijremolars in 
P. Amk.” 
Mr. Lydekker unites the specimens with Frotemnodon anah, Owen, in part, and 
Sthenurus atlas, Owen, in part, and refers them to Macropus.

Ois. In a left mandibular ramus “ the molars have the characters of those of 
P. anak . . . but the increase in size is more than can be granted to difference 
of sex.”

Obs. The form and structure of the premolars in this and its fellow species, as 
compared with their proportion to the molars behind, indicate, according to Prof. Owen, a 
distinct sub-genus of Macropodidee. The name Sthenurus was suggested by the form 
and proportions of the vertebrae of the very powerful tail of this great extinct Kangaroo. 
The portions hitherto recorded consist of jaws with teeth, portion of a skull, and tail 
vertebrae.
