240 THE KANGAROOS. 



SUBGENUS 3. 

 Pdrogale, Gray. Heteropus, Jourdan. 



Mr. Gray * deliiies this group tliiis : — " Muzzle 

 baldj distinct. Canine teeth, none ; the upper cut- 

 ting teeth are equal ; front rather longest, and incurv- 

 ed ; the hinder one hatchet shaped, dilated at the top, 

 and notched in the centre, (scarcely folded.) The 

 tail cylindrical, covered with long, rather rigid hairs, 

 forming a tuft at the tip." Type, Macropus peni- 

 cillatus, Gray. 



Nearly at the same time that the above characters 

 appeared in the work quoted, M, Jourdan character- 

 ized a genus under the name of Heteropus, in a paper 

 which was brought before the " Academic des 

 Sciences." t This genus I feel no doubt is identical 

 wdth Petrogale ; M. Jourdan's characters are : — Legs 

 moderately long; tarsi short and thick, covered with 

 bushy hairs, the under surface broad and destitute of 

 hairs, but covered with flattened corneous tubercles ; 

 third and fourth toes furnished with nails like those 

 of a dog. 



Mr. Bennett, however, has the credit of having 

 lirst pointed out the characters of this section. (See 

 Proc. Zool. Soc. for January 1835.)
