forest-species. 
This genus cannot be confused with any of the smaller 
Oriental, African, or American genera of Felidz. Perhaps 
Pardofelis is its nearest ally. By Severtzow it was associated 
with Uncia, by Trouessart it was placed with serval, par- 
dals, and others in Zibethailurus. From Panthera pardus, 
with which it has been compared above, it differs in the 
hyoid bone ete. 
Genus Lroparpvs, Gray. 
LTeopardus, Gray, 1842, p. 260; type griseus, Gray (=? pardaiis, 
Linn.) *. 
Oncoides, Severtzow, 1858, p. 886; type pardalis. 
Pardalis, Gray, 1867, p. 270; type pardalis. 
Distr. From the Sonoran district of North America 
southwards throughout the forested districts of South 
America. 
An uncertain number of species or subspecies referable 
to two groups typified respectively by pardalis and wiedit 
(macrura). 
Moderately large or medium-sized cats, with the ears 
small, rounded, and white-spotted; the rhinarium promi- 
nent and naked above, and with widely separated nostrils ; 
feet fully webbed and with well-developed claw-sheaths 
concealing the tips of the retracted claws; hair on tie 
neck upright or reversed in direction of growth in the 
adult. 
. Skull variable in size and shape, and in the typical form 
of Levpardus most like that of Profelis of all the genera of 
the Old World, but differing in the sum of a number of 
characters. The nasals, though broad in front, are narrower 
posteriorly and fit like a wedge between the mayille, which 
are differently shaped above from those of Profelis, being 
broader and more truncated at the summit, the suture 
between them and the nasal processes of the frontal inclining 
more obliquely inwards and forwards from the dorsal aspect 
* Gray originally included four species in this genus, namely, griseus, 
pictus, elliott, and horsfieldi, but subsequently assigned griseus and putus 
to Pardalis, ellioti to Viverriceps, ignored horsfieldi, and applied Leo- 
pardus to pardus and onea. Since Leopardus must unfortunately stand 
for one of the four species first included under it, I selected griseus, 
perhaps a subspecies of pardalis, as the type (Ann. & Mag. Nat. Hist. 
(8) xviii. p. 316, 1906),
