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 mamme, 
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 fish, birds, 
and small animals.
