Hah. South America. 



Skull 820 a is very like those figured by Burmeister, t. 28. f. 2, 

 t. 29, f. 2 ; but the lower edge of the lower jaw is not so much 

 arched. 



Skulls 821 a and h both differ from 820 a in the upper sectorial 

 and the tubercular grinders being smaller than they are in that skuU. 

 In 820 a the upper sectorial tooth is thick, nearly triangular, broad, 

 and with a well-marked lobe on the front of the inner edge. In 

 821 a it is nearly of the same form — if anything, rather more equi- 

 laterally triangiilar ; but it is smaller than in 820 a.

It is evident that the teeth of these Dogs vary in size in the same 

 species.

Upper sectorial tooth compressed, with inner front lobe rather in
