AGUARA DOG OF THE WOODS. 
Dusicyon sylvestris. 
PLATE XXIV. 
In the collection of original drawings of the Prince 
of Nassau, now in the Berlin library, there is one 
of an animal with the name Aguarra beneath it ; 
the design evidently shows a form of the present 
group ; the head is pointed, the forehead round, the 
ears large, somewhat obtuse, rufous at the back and 
on the edges; the body is slender, the fur yellow- 
ish grey, darkest on the back; from the eyes to the 
nostrils the face is blackish; the legs are rather stout ; 
all the feet as far as the joints black, the rest of the 
limbs rufous; the tail does not reach the ground, 
and from the root to the black tip it is yellowish 
grey. The size of this animal is not mentioned, nor 
can it be identified with any other of the group. 
Professor Lichtenstein, in his observations on Mare- 
grave and Piso, has not ventured to assign it to a 
described animal, but we have little doubt but that 
it is a true wild species, and therefore that the name 
of Dusicyon sylvestris should be admitted ; for we 
have seen skins of one or two specimens in their 
wild condition and mutilated, but enough to satisfy
