^vithout thickening, but a deep bridge above the preorbitf*! 

 foramen, and tlie 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 ed<<e 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 

 glenoid ridge, its outer chamber as large as the inner, the 

 partition extending to the occipito-sphenoidal suture; small 

 upper first premolar and inner cusp of caruassial suppressed*. 

 Trich(Elurus is in some particulars intermediate between 

 Felis and Lynx, the circular pupil, narrower premaxillie, 

 shallow notching of suborbital e(.\^e 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.

INIany species or subspecies, according to the fancy of 

 authors. 



Large, long-tailed cats with comparatively small, rounded, 

 black ears without a white ])atch ; the pattern J, suppressed 

 in the adult, consists in the cubs of solid dark spots and 

 blotches of irregular shape^ often arranged on each side iu 

 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 tiie ear, 

 as in typical Felidae. The rhinarium is naked above and 

 moderately prominent. Except that the feet are broader, 

 they do not differ greatly iu form from those of Felis in tiie 

 development of the webs aiid claw-sheaths. 



The skull is short and broad, with complete sagittal crest, 

 moderately deep and rounded postorbitai constriction, quite 

 short, widely separated postorbitai processes, and salient

I Although Jardiue included F. yagimrondi, pajeros, and others with 

 concolor imder 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.
