neral shape of the animal resembles that of the Kan- 

 garoo, but is far less elegant, the proportion of the 

 parts less pleasing, and the hair, which is a dusky, 

 cinerous brown, of a coarser nature. In its teeth it 

 agrees with the great Kangaroo, except that it has 

 eight instead of six front teeth in the upper jaw, the 

 two middle ones being sharp-pointed : the fore teeth 

 in the lower jaw are like those of the Kangaroo as to 

 shape and position, but are smaller in proportion ; 

 the grinders are three in number on each side both 

 above and below, the foremost being fluted or chan- 

 nelled with several longitudinal ribs; the two re- 

 maining ones plain. The structure of the hind feet 

 in this species resembles those of the Kangaroo, but 

 the fore feet have only four toes. The female is 

 furnished with an abdominal pouch for the reception 

 of the young. Some of this species were imported in 

 a living state from New Holland, and brought forth 

 young. Its native name is Poto Roo,
