THE AGUARA DOGS. 249 



heel ; the body is long, compared to the height, and 

 bulky ; the feet are smaller, a characteristic ex- 

 tended over a great proportion of the mammalia of 

 South America, including even man. They have 

 often the fulvous brown, only in shades deeper than 

 the Chrysean group, or it is hoary, and the face has 

 the aspect of foxes. The individuals we examined 

 had the roof of the mouth black, only six mammae, 

 and the eyes rather more oblique than the domestic 

 species of the old continent. They are less shy than 

 the Chrysocyon, in proportion better armed ; they 

 burrow, and therefore prefer more open countries, 

 swim, detach clams from rocks, and eat lish, birds, 

 and small animals.
