hx 
body a pale yellow color; the snout reddish-brown. 
The coronal ridge is narrow and linear. Maximilian 
regarded this species as Canis azarae. It inhabits 
Brazil. 
YELLOW-TAILED WOLF {Lycalopex fulvicaudus, 
Burm.) — Again we apply a name extracted from the 
specific designation of Burmeister, the under side of 
the tail being a reddi'^h-yellow or fulvous. The tem- 
poral muscles are separated by a well-marked, narrow 
lanceolate crown, which is linear for one fourth of its 
length behind. The upper sectorial tooth is short, 
broad and thick ; the upper tubercular teeth are 
large, aud nearly similar in size and form. This is 
called by one author Canis fulvicaudatus. Its habitat 
is South America generally. The teeth of these 
creatures vary in size in the same species. A variety, 
L. chiloensis, has the upper sectorial tooth com- 
pressed, with the inner front lobe rather in front of 
the front edge of the tooth. The crown of the skull 
is flat and narrow, and sub-vase shaped ; the hinder 
opening of the palate, broad and expanded. Water- 
house called thisVulpes azarse, and Cerrard, V. vetu- 
lus. Its habitat is Chiloe. 
PsEUDOLOPEx. — Burm. 
This genus has an elongated tail, reaching below 
the hocks. The pupil is elliptical in the daylight. 
T’he skull has a linear coronal ridge. The upper 
tubercular teeth, taken together, are scarcely so long 
as or very little longer than the flesh tooth. Two 
groups are noticed in this genus ; the following has 
the fore-legs gray externally, and soles of the feet a 
blackish-brown. 
THE AGOUARACHY {Pseudolopex azarcB, Burm .) — 
This is the most familiar species of the tribe. Maxi- 
milian described it, as well as the two preceding- 
species, under the present specific name. Gray and 
Vanderhoeven also called it the same; Schinz had 
it Canis braziliensis, and Wagner-, C. melanostomus. 
The eminent naturalist, Azara, was honored by 
the present nomenclature. The first portion of the 
trivial name is synonymous with raposa, fox and 
zorro — local designations ; the terminal, “ chay,” being 
regarded as only added to distinguish it from the native 
name of Canis jubata. Its range is from Brazil, 
through Paraguay, to Patagonia; Darwin met with 
it in the latter region. Mr. Waterhouse, in a com- 
munication to the Zoological Society of London, 
speaks of this Fox-tailed Wolf as smaller than the 
C. magellenicus, and less common and mischievous, 
more shy in manner, and as confining itself more to 
the lower parts of the country, inhabiting the prov- 
inces of Valparaiso, Aconcagua and Colchagua. It 
is well known to the natives under the name of 
Chilla. The tubercular molars are three in number, 
the front always the largest. Azara describes this 
species as follows : “ The ear is three and three- 
quarter inches in height, and two inches in breadth 
at the base. The head is six inches long- ; at the 
broadest part it is three and a half inches wide. 
The ears are two inches apart, which distance is 
reduced to less than half at pleasure. The canines 
were six lines long, though worn. It has three pairs 
of mammae. The hair on the loins and tail is three 
inches in length ; on the muzzle and ears, very short. 
'I’he outer part of fore-leg, as far as the claws, reddish- 
cinnamon in color, like the outer part of the ear ; the 
hind-leg, to within two inches of the claws, the same. 
The muzzle, as far as the eyes, is blackish, and the 
remaining- parts of the head are covered with cinna- 
mon-colored hair, with white tips. 'I’he lower jaw is 
black on the under parts, and the remaining parts 
under the head are white. All the inferior parts 
of the body, with the inner parts of the hind- 
legs, are whitish, although in reality the tips of the 
hairs are white, and the inner parts dark. The 
rest of the coat is a mixed gray, proceeding from 
each hair, having two white and two black bands, 
the tips being of this last color, which predominate 
greatly in the loins and tail. T’he tip of the former 
is almost black. In addition to what is stated 
above, there is another interior coat or down of 
a white color, very soft, one inch long. 'The young 
at first are almost entirely black.” 
GRAYISH-YELLOW WOLF [Pseudolopex griseus, 
Burm.) — This is one of the second group, which have 
the fore-legs entirely red-yellow, and soles of the feet 
red-brown in color. The fur is a reddish-yellow-gray. 
The body is small. It is the Canis griseus of Gray, 
and Vulpes griseus of Gerrard. Habitat, Patagonia, 
THE COLPEO {Pseudolopex magellenicus, Burml) is 
one of the same group as the preceding, but much larger. 
It has a red fur, the back being black. Waterhouse 
called it Canis azarte ; Molina, C. colpaceus; Mayer, 
C. tetradactyla ; and Shaw, the Chili Fox. It in- 
habits Chili and Bolivia, and Darwin saw it in the 
Straits of Magellan. 
THE ANTARCTIC FOX {Pseudolopex antarcticus ). — 
'I'his is pretty well known to voyagers to the South 
Pacific. Darwin, in Voyage of the Beagle, mentions 
it, and predicts its entire extinction from the Falk- 
land Islands — its most notable habitat. It is very 
circumscribed in range, and is seldom seen elsewhere. 
THE SLENDER FOX [Pseudolopex gracilis, Burm.) 
— This is another form recorded by Dr. Gray without 
any convenient popular designation. It is presumed 
to be somewhat more graceful or slender than others 
of the group, othervvise it is inconceivable why it Is 
called gracilis. Burmeister describes it in Peise La 
Plata, vol. ii, p. 406. It is also mentioned in Arch. 
Naturg., 1862, p. 130. It inhabits the Pampas of 
Mendoza. 
Tuous. — Gray. 
This genus was originally a part of Lycalopex, but 
is instituted separately to include two species. The 
skull is elongate, the nose tapering and moderate in 
length. The temporal muscles are separated by a 
base-shaped crown. T'he teeth are forty-four in 
number — twenty on the upper and twenty-four on 
the lower jaw. On each side of the upper jaw are 
two tubercular grinders, and three in each side of 
the lower jaw. The two hinder are circular, the 
hindmost very minute. 
THE CRAB-EATING FOX [Thous cancricorus, 
Desm.) — Mayer, in Zoological Annals, calls it Yiverra
