of authors); color lighter and g-raj^er. Skull strongly constricted 
postorbitally, flattened superiorly. Mammae, 3 pairs. 
Colour in summer (based on specimen No. ffffT? U.S.N.M., Biological 
Surve}^ collection; adult female, taken at Brownsville, Texas, June 14, 
1892). — Seen at a distance, the animal appears of a nearly uniform 
smoke-gray color, without strong contrasts. On close inspection the 
under surfaces of body and tail are seen to be considerably paler 
than the upper, and certain light and dark areas are apparent. Upper- 
parts, including upper side of tail and outer surface of limbs, uni- 
form pepper-and-salt graj^; underfur and concealed bases of the 
coarse overhair whitish gray; overhair 10 to 20 mm. in length, 
pointed with black and ringed with white, bufl', and black. Under- 
parts paler, manj^ of the hairs, especially of axillje and hollows of 
thighs, being tipped with whitish. Under surfaces of fore and hind 
feet strongly tinged with bistre. Under side of tail whitish smoke- 
gray, the overhairs narrowly ringed with black. Head with areas of 
light bufl'y gray bordering the blackish eyering, on chin and throat, 
and within and behind ear; a short, narrow line of blackish midway 
between eyes, and another between ears, and faintly brownish black 
edges to the ears; muzzle tinged with wood brow n. Whiskers mostly 
white, shading apicall\" to hair brown; stiff hairs above orbits, 10 to 
15 mm. in length and uniform hair brown. Claws light horn color. 
Color in winter (based on specimen No. fflH? U.S.N. M., Biological 
Survey collection; adult female, taken at Brownsville, Cameron 
County, Texas, February 23, 1892). — Darker, pelage longer, with a 
greater amount of black in vertebral area than laterall}^; under side of 
feet bistre, upper side more mixed with brownish black; otherwise 
similar to the summer pelage al)ove described. 
Skull and teeth. — Skull compressed in front of orbits and flattened 
above; braincase narrow and strongly constricted postorbitally; nasal 
processes of frontals ending well in front of the plane of malar bone; 
nasal bones elongated laterally and strongly depressed; zygomata 
relativel}^ broad posteriori}^; audital bullas large and high, antero- 
laterally compressed; posterior narial fossa wide. The canines, upper 
carnassials, and middle superior premolars are about the size of the 
same teeth in specimen No. 10018, U.S.N.M., assumed to represent 
the Fells yaguarondi tolteca of Thomas; but the upper lateral incisor, 
first premolar, and true molar are larger teeth. A supernumerary 
first upper premolar is present, on the right side only, in female No. 
35953, U.S.N.M,, from Texas (see measurements). 
Remarks. — Mr. Oldfield Thomas ^ separates a subspecies tolteca 
from the true Felis yagaojvundi of Paraguay. I have identified with 
^Annals and Magazine of Natural History, 7th ser., I, p. 41, January, 1898.
