pairs of males and females go together. The young are born in the spring, and 
generally comprise from three to four in a litter. The lair may be formed either 
beneath the cover of a thick bush, or in the deserted hole of another animal, such 
as an armadillo, but it does not appear that the aguarachay (as this species is 
termed in South America) ever burrows for itself.

AZARA’S DOG. 
AR The crab-eating dog (C. canerivorus), is a rather larger species 
than the last, sometimes attaining a considerable size; and having a 
relatively shorter muzzle and tail. It inhabits the regions from Guiana and 
Demerara to La Plata, although said to be unknown on the Pampas. The colour 
is subject to great individual variation, but according to Mivart its pervading 
tint may be either a uniform light reddish grey, or darker and mottled. It 
may have a black back and bright red legs, or may be a dull grey, with very 
little black, or grey with a very black back. The most normal tint seems to be a 
brownish grey above, with the crown of the head, sides of the body, and outside 
of the limbs slightly or strongly rufous. There is generally more or less black on 
the back and the upper surface of the tail, while the end of the tail is always 
black. The reddish brown ears have not the black tips of the preceding species. 
The carasissi, as this dog is called in some parts, is a forest or jungle-dwelling 
species, feeding not only upon rodents and birds but likewise upon crustaceans,
