Costa Rica, collected by William M. Gabb; now No. 2853 in the collec¬ 
tion of the Philadelphia Academy of Natural Sciences, on which the

Remarks .—This is the largest North American yicelot. Quite singu

Type locality. —South America. 
Geographic distribution. —Brazil and northeastern South America. 
General characters. —Size medium. Coloration pale; ground-color 
fulvous anteriorly, grayish posteriorly. The skull most resembles 
that of Tells par dalle Linnaeus. 
Color. — Pattern as in the preceding species, but with the black 
markings everywhere restricted. Ground-color tawny anteriorly, fad- 
ing to grayish posteriorly, or light clayfcolor in the black-bordered 
spots, which are usually open anteriorly. The ground-color within 
the black-bordered chains of spots is decidedly darker than that between 
them; and a similar contrast is afforded by the coloration of the ante¬ 
rior and posterior portions of the upper parts of the animal. The 
tail is very irregularly spotted with black above, with only about 
three distinct subterminal rings. 
Shull and teeth. —The skull and brain ease are narrow, the teeth 
large, and the audital bulks elongate. (See table of cranial measure¬ 
ments.) 
Measurements. — Adult male (skin): Length, 1,150 mm.; tail verte¬ 
bra*, 340; length of hind foot, 160; ear above crown, 50. Skull 
(adult male): Basilar length, 125; zygomatic breadth, 100. Largest 
female: Basilar length, 105; zygomatic breadth, 93. 
lie marks .—In the South American Ocelots the gray patch on the 
back of the ear is usually surrounded by black, narrowly at edge of 
ear; but in North American /xTelots the gray spot usually extends to 
the margin of the ear, in F. Inn It. is often cutting off the posterior 
horn of the black crescent. 
FELIS 2EQUATORIALIS, new species. 
ECUADOR OCELOT; TIGRILLO. 
Type, — No. 113267, U.S.N.M. Adult female, collected at Paramba, 
northern Ecuador (altitude 3,500 feet), November 2,1899, by G. Flem¬ 
ming. (Original number, 22.) 
General characters. —Size very large. Ground-color tawny-rufous. 
Spots of upper parts all black, not inclosing lighter areas. Postorbital 
>rcg.dth of skull greater than length of nasals. 
i " - • be type (November) is heavily marked with black on a 
ground of tawny above and smoke gray below. Upper parts tawny, 
tinged with rufous, of almost uniform intensity. Black pattern similar 
to that of Fells pardalls Linnseus, except for its greater intensity. 
The black markings only inclose light areas upon the sides, where the 
inclosed areas are much smaller and very much less elongated, bearing, 
in fact, a close resemblance to the pattern of Fells onga. Upper side 
of neck with six longitudinal stripes, beginning between the ears and 
ending in front of the shoulders. The stripes forming the middle pair 
are nearly parallel, about 4 mm.,wide and 5 to 10 mm. apart; those of 
the next pair begin 20 mm. apart and'(iff the skin) end 55 mm. apart, 
having a width of 5 mm. anteriorly and about 15 posteriorly. The 
outer stripes begin 10 mm. internal to the ear, pass downward and out¬ 
walk! to the median outer side of the neck, having a pretty uniform 
width of about 5 mm., except where narrowly bifurcating posteriorly. 
Four irregular rows of solid, glossy-blapk spots extend from the 
shoulders 'to the hips; these are mostly elongate, from 5 to 15 mm. in 
width and 10 to 60 mm. in length. The oblique area of light bordered 
with black between hips and shoulders, and the transverse black stripes 
at the shoulders (characteristic of Fells pardalls) are not plainly indi¬ 
cated, but, instead, are broken up into spots which even form rosettes. 
On the outer faces of the fore and hind limbs the tawny color becomes 
slightly paler, and grayish on the feet. On the fore limbs the black 
spots are rounded, and decrease from above downward, ranging from 
3 to 18 mm. in diameter; the same being the case on the hind limbs, 
where the spots vary from 3 to 25 mm. in diameter. The tail is red¬ 
dish tawny above, irregularly spotted with black on basal three-fifths, 
with five transverse subterminal black bands on last two-fifths, the 
last three forming continuous rings around the tail. The widest tail¬ 
ring is 40 mm. in width. Inner surface of ear light tawny; outer 
surface black, inclosing a rectangular 1 gray spot measuring 13 by 
18 mm. Top of bead with two parallel, black, longitudinal stripes, 
about o mm. in width and 40 mm. apart, extending from above the 
inner canthus of the eye to opposite the front of the ears. Space 
between the stripes, and between the ears, spotted with black; in all 
about forty spots, varying from 3 to 10 mm. in greatest diameter. 1 
Side of head with two heavy black stripes, each about 7 mm. in width, 
the upper beginning at the outer canthus of the eye, the inner midway 
between the last point and the margin of the upper lip, these two end¬ 
ing separately at side of neck below and behind ear. The large trian¬ 
gular space between the black crown-stripe and the upper lateral stripe 
is unspotted. On either side of underpart of the neck is a black spot, 
shaped like a riding boot with the heel pointed toward the end of the 
lower jaw, the toes separated by a space of 30 mm. in the median line. 
Chiu and throut buffy^vhite. Side of neck with a longitudinal black 
stripe 70 mm. in length and 10 mm. in width. Under surfaces and 
inner sides of limbs smoko gray. There is a very faint bufiy-gray 
pectoral collar, interruptedly bordered with black anteriorly. Under- 
jaarts spotted with black, sparingly on neck, axilla* hollows of 
thighs; most thickly and heavily blotched with black on chest, where 
the spots vary in size from small dots to blotches 40 mm. in diameter. 
Underside of tail grayish buff, irregularly cross-banded with black; 
tipped slightly with gray. Eye-ring and crescentric area at either side 
of nose, black. Whiskers mixed black and whiteywithynve transverse 
lines of black spots bordering theyfip on each side of the nasal pad. 
Muzzle above, plain tawny.
