Shull and teeth. — Compared with Fells par dal! a Linnaeus the skull 
is smaller, relatively short and broad, the interpterygoid fossa averag¬ 
ing considerably wider and more quadrate. The audital bullae are 
relatively short, and more inflated than in any other form; and the 
postorbital processes are more flattened and less depressed, lhe den¬ 
tition is relatively weak. 
Measarei I Lent*.— Adult male: Length, 1,080 mm.; tail vertebra', 330; 
length of hind foot, 100; ear above crown, 50. Adult female: Length, 
950; tail vertebrae, 300; hind foot, 1-15; ear above crown, 50. Skulls: 
Greatest diameters of largest male, 1-10 by 93 (basilar length of llen- 
sel, lid); largest female, 126 by 87. (Sec table of cranial measure¬ 
ments, p. a .) 
Remarks . — It is uncertain whether the Ocelot referred to by Dr. 
Richard Harlan and other early writers as occurring in Arkansas and/ 
Louisiana was precisely the same as the present form. Ilarlan /m-

Type locality. —Mexico. 
Geographic distribution. —Southern and eastern Mexico. (It is 
uncertain whether this form occurs in northwestern Mexico.) 
General characters.— Decidedly larger than Felix limitix. Ears 
large. Black markings extended. The ground-color within the black 
circles contrasts strongly with that outside of them; and the chains 
of black-bordered inclosures are broken up into patches, which com¬ 
mon Iy contain black spots. The skull is relatively narrow; dentition 
heavy. 
Color.— There are three principal colors—black markings, ground- 
color outside the black circles, and color within the circles. The 
general ground is pale grayishjbuff; within the black rings, dark clay 
color. The pattern of the black markings is similar to Felix Irmitix , 
differing in having the chains of black-edged inclosures broken up 
into shorter patches, and the longitudinal black necl^stripes more fre- 
quently double, inclosing clay-colored stripes. On the fore limbs the 
black markings are disposed in irregular rosettes or rounded spots, 
while in F.Umitbs they tend to form transverse bands. The tailorings 
contain irregular areas of russet. The gray ear spot is small, and 
barely reaches the edge of the ear; and there is no distinctly grayish 
area bordering the posterior margin of the car. as there is in limitix. 
The coloration as a whole is more intense.

Remarks. —Skins, unaccompanied by skulls, in the collection of the 
American Museum of Natural History in New York—one from Ari¬ 
zona, one from Sonora, and two from the State of Colima, Mexico (the 
latter collected by Dr. Buller)—are of a peculiar pattern and grayish 
coloration, quite different from either limitix ox pardalix; but, in the 
absence of skulls, the form can not be differentiated. 
FELIS COSTARICENSIS, new species. 
COSTA RICAN OCELOT. 
7^._Skull No. 11180, U.S.N.M. Adult male from Talamanca, 
Josta Rica; collected by William M. Gabb. (The skin, No. 12180, 
I.S.N.M., seems to have been destroyed.) 
General characters— Size very large. Ground-color decidedly tawny. 
flack markings extended and very intense. Ear smaller than in Felts 
'vutis. Skull narrow, osseous, with a heavy dental armature. 
Color .—Pattern similar to that of Felix pardoMs and F. limitis. 
Coloration like that of id pardalix , but with black markings increased 
) area and intensity. Neck with median pair of black stripes con- 
olidated, so there are but live longitudinal stripes on upper side of 
eck. Ears black, with the gray patch extending to margin and meas- 
tring 8 by 25 mm. Upper parts with ground-color russet, becoming 
riwny-olive on the inclosed areas of the spots, and cream-butt betw een 
lie chains of spots on the sides. A heavy black stiipe, 250 mm. in 
mgtli, occupies the median dorsal area, the row of spots on either side 
ieing solidly black, elliptical, measuring about 15 by 20 mm. 1 he 
ateral-dorsal spots all heavily inclose areas of tawny-olive, except 
Ulteriorly, where they are sometimes open (c-shaped),. the spots 
ieing 20 to 10 mm. in length and half as wide, varying in size and 
hape within the usual limits. Tail with more black than light; about 
■[even crossbars of black, encircling the tail more narrowly below 
han above. A broad collar of black crosses the under side oi the 
Lead behind the throat, and the pectoral collar is likewise continuous. 
1'he under parts are cream-buff, with the usual black spotting, the 
argest blotches on the chest measuring 25 mm. in greatest diameter. 
1'he russet ground-color of the upper parts becomes less intense poster- 
orly, but much less markedly so than in the Brazilian Ocelot, which 
dso differs in having most of” the lateral spots c- or c-shaped, open 
interiorly.
