The Swift Fox, V. velox, Aud. & Bach., of Oregon, is 

 smaller than the Red Fox, the general color yellowish 

 gray above, back conspicuously grizzled, sides and por-

 whitish, tail tipped with black. 



The Arctic Fox, V. lagopus, Rich., of the Arctic re- 

 gions, is smaller than the Red Fox, of a white color, the

VIVERRID^E, OR CIVET FAMILY. This Family' com- 

 prises small animals of the average size of the domestic 

 cat, but more elongated, and with a more pointed muzzle, 

 and with a long tail. In most cases the feet are digiti- 

 grade, with hairy soles and retractile claws. The dental 

 formula is, incisors ~, canines ~^ premolars ^ molars 

 A The dentition differs from that of the dog family in 

 having one tubercular true molar less on each side of the 

 lower jaw. They secrete in a sort of pouch or gland a 

 substance formerly much used in perfumery, and which 

 was long an important article of commerce. With one 

 exception, they belong to the Old World. 



The Genus Bassaris is represented in North America 

 by the Civet Cat, B. asttita, Licht., of Texas to California. 

 This animal is about the size of the domestic cat, but 

 more slender ; the color above brownish yellow mixed
