MAMMALS—VIVERRIDAE—BASSARIS ASTUTA. 147

Licut. Darstellung Siugt. 1827-34. 
Head short, acuminate; ears large; feet digitigrade, five-toed; soles hairy, with naked pads; tail as long as the body, 
annulated. 
This genus, confined to Mexico, and the more southern parts of the United States, is the sole 
representative in the new world of the genets, civets, ichneumons, mangoustes, suricates, &c., 
of the old. The body is slender and elongated, the muzzle pointed, the ears projecting, the 
tail long, and ringed with black and white. The claws are half retractile, five on each foot. 
The skull is intermediate in form between that of the martens and the civet cats, and like 
them exhibits only an indication of the post-orbital process of the frontal bone. 
The dental formula is as in the typical Viverridae, but differ from that of Viverra, in having 
the inner process of the upper sectorial tooth much more developed, and reaching to the middle 
of the tooth ; the anterior lobe of the lower sectorial shorter than the two middle. 
It is as yet uncertain whether America possesses one or two species of Bassaris, further inves- 
tigation being necessary to determine the character of the California species. They are found 
as far north as Red River, Arkansas, on the eastern slope of the continent; on the western to 
the latitude of San Francisco; southward they extend throughout temperate Mexico. They 
bear in the United States the name of civet, Mexican, or ring-tailed cats, and are frequently 
tamed in Mexico and California ; in the latter country they are great pets of the miners. 
Very little is known of the internal anatomy of the genus, or as to the precise measure of 
their relationships to the other Viverridae. They have at least four young ata birth, this being 
the number of a litter found by Mr. Clark on the San Pedro, Texas.

Sp. Cu.—Size about that of the domestic cat, but rather more slender. Above, brownish yellow, mixed with gray ; beneath, 
white ; tail white, with six or eight black rings. 
No specimens of this species were collected by any of the expeditions, although several were 
brought in by the United States and Mexican Boundary Survey, in the reports of which a full 
description will be found. 
Only one authenticated skin, (No. 2343,) has been received from California ; this is a hunter’s 
skin, not sufficiently perfect to furnish a full description.
