as the bellies of the specimens brought by D’Orbigny are exactly as he described them to be— “ white, spotted with brownish
black." The F. guigna of Molina, on the other hand, has but little to do with F. geoffiroyi; and it is most probable, as
stated by Molina himself, that his animal is merely a variety or variable specimen of F. tigrina.
Fur rather soft and thick. General colour rufous ; body covered with small black spots, which on the back are rather
pointed at one end, and largest on the hind quarters. Head rufous, with two narrow black lines down each side of the
centre, extending onto the back, where they become broad; two black stripes on each side of the face; cheeks and
throat white, a black band across the lower end of the under jaw, and a black stripe on each side of the throat and one
across the upper part of the breast. Shoulders spotted like the hind quarters. Belly white, spotted with brownish black;
two black bars inside of front legs, and four inside of hind legs. Tail long, same colour as body, narrowly ringed and
tipped with black, the under portion greyish in the centre. Ears behind black, with a white spot in the centre.
M. Alphonse Milne-Edwards kindly drew my attention to an individual of this species which was received from the
Upper Parana, and died in the Jardin des Plantes. I t is peculiar for its light colour, which is a pale-yellowish brown,
thickly covered with small black spots all over the body and hind legs ; on the fore legs they take the form of irregular
bars. Top of head of a slightly greyish hue; but the cheeks and neck are yellowish, like the body. The usual cheek-stripes
are present, and also the lines on back of head and neck, not continued, however, upon the back. Chin and upper part
of throat white, fore part of neck b u ff; a broad black bar crosses the lower part of throat; and there is one on the upper
part of breast. Underparts and inside of legs white, spotted with black on the former and barred on the latter. Tail same
colour as body, irregularly and narrowly ringed with black. Length of body 25 inches, tail 15 inches. This specimen has
the spots rather smaller than the typical style, and the tail less broadly ringed. It is probable that in a large series of
specimens individuals would be found to exhibit all variations of spots, from that represented in the lower figure in my
Plate to the profusely and minutely spotted specimen just described, these two being the extremes.
The skull of the species is peculiar among those of the Cats by its strongly marked characteristics. It is broad, with a
very short face and a rather high arched forehead ; nasals moderately broad, and curving outwards and backwards towards
their frontal articulation. The skull viewed in profile shows that the facial region is highest above, and from this part shelves
gradually backwards towards the supraoccipital region. Postorbital process of frontal bone unusually lengthened and
slender; orbits moderate, incomplete; lower outline of mandibular ramus much curved between symphysis and angle.
Upper canines moderate in size. Processes of maxilla very broad and square at their upper posterior ends.
