without thickening, but a deep bridge above the preorbital 
foramen, and the malar continued as a thin strip up to the 
frontal in front of the lacrymal foramen ; nasal branch of 
premaxilla not broad, evenly attenuated ; anterior nares set 
low down, the upper edge hardly above the inferior edge of 
the orbit; palate wider than long, without conspicuous 
notch on the suborbital edge; basisphenoid markedly con- 
cave longitudinally ; bulla advancing slightly in front of the 
elenoid ridge, its outer chamber as large as the imner, the 
partition extending to the occipito-sphenoidal suture; small 
upper first premolar and inner cusp of carnassial suppressed *. 
Trichelurus is in some particulars intermediate between 
Felis and Lynx, the circular pupil, narrower premaxille, 
shallow notching of suborbital edge of palate, and suppression 
of small upper premolar being lyncine characters. The 
genus, however, may be easily distinguished by the sum of 
a number of structural peculiarities. 
Genus Puma, Jardine. 
Puma, Jardine, 1834, p. 266; Severtzow, 1858, p. 125; type concolor, 
Linn.f. 
Distr. From the United States to Patagonia. 
Many species or subspecies, according to the fancy of 
authors. 
Large, long-tailed cats with comparatively small, rounded, 
black ears without a white patch ; the pattern [, suppressed 
in the adylt, consists in the cubs of solid dark spots and 
blotches..f irregular shape, often arranged on each side in 
about four ill-defined rows and one along the spine ; and on 
the head and nape there are often four longitudinal stripes 
and one running backwards from the eye beneath the ear, 
as in typical Felide. The rhinarium is naked above and 
moderately prominent. Except that the feet are broader, 
they do not differ greatly in form from those of Felis in the 
development of the webs and claw-sheaths. 
The skull is short and broad, with complete sagittal crest, 
svoderately deep and rounded postorbitai constriction, quite 
short, widely separated postorbital processes, and salient 
- ae pare particulars about this cat see Pocock, P. Z. 8. 1907, 
. 299-306. 
ae Although Jardine included F. yaguarondi, pajeros, and others with 
concolor under Puma, concolor is indicated as the type-species by its 
ownership of the trivial name “ puma,” quite apart from the restricted 
association of the two names by Severtzow.
