than in Profelis, and the facial portion of the frontal ante- 
rior to the root of the postorbital process is larger and the 
lacrymal extends higher above the malar arch within the 
orbit. The skulls are variable in these respects, but, on the 
whole, the arrangement of the bones above described gives a 
different aspect to the skulls of Leopardus as compared with 
Profelis. The mesopterygoid fossa is more pointed as a rule 
in front, and has more sinuous margins owing to the curva- 
ture of the pterygoid bones. The bulla are differently 
shaped from those of all the Old-World tiger-cats in that the 
portion behind a line drawn from the stylomastoid foramen 
at right angles to the occipital axis is larger than the portion 
in front of it. 
In the mandible the condyle is not so high above the 
angular process as in Profelis, the first premolar is higher as 
compared with the carnassial than in that genus, and when 
the jaw is closed reaches up to the comparatively large first 
premolar of the maxilla, so that, as in Leptailurus, the post- 
canine space is quite small—a feature not observable in the 
Asiatic tiger-cats, 
In addition to the true ocelots, often called jaguars *, I 
refer to this genus L. wiedii (macrowra), commonly cited as 
tigrina +, which may be described as a small, long-tailed, 
smooth-skulled representative of the ocelots. The skull is 
like that of a young ocelot in most respects, showing at most 
a shallow postorbital constriction, with the temporal crests 
forming a lyriform area generally wide but varying in width 
with age and possibly locally. The skulls differ, however, 
from those of ocelots in having a tolerably regularly rounded 
low occipital area; even when the occipital crest is well 
developed its edges have no definite lateral emargination ; 
and the inferior edge of the orbit is thin, with the preorbital 
thickening hardly developed. In this last-mentioned parti- 
cular, as well as superficially and in size, the skulls recall 
those of Pardofelis, but the maxille are wider above, the 
nasals narrower posteriorly, the malar arch is shallower from 
above downwards, the postorbital processes, although as long 
as in Pardofelis, are thinner, the back of the cranium is 
longer, and the occipital plane more vertical, the posterior 
part of the bulla is larger, the sides of the mesopterygoid 
fossa thinner, and the chin much more sloped. 
* Schreber’s figure of Felis onca, Linn., represents an ocelot (Leo- 
pardus pardalis), and not the species which is trivially known as the 
jaguar (Panthera onca). :
