Revision of the Coyotes. 23 



legs, and distal half of the under side of the tail are some shade 

 of fulvous. The ground color of the back also varies from buff, 

 or even buffy- white in the desert forms, to dull fulvous in the 

 animal from southern Mexico, and the abundance of black- 

 tipped hairs is usually proportionate to the intensity of the 

 ground color. The upper side of the tail is like the back, and 

 about one-third the distance from root to tip it is marked by an 

 elongated black spot. The tip is always black, although it some 

 times contains a tuft of white hairs, most often present in C. 

 ochropus. The males are decidedly larger than the females. 



Compared with the large Wolves, the Coyotes are slender, lithe, 

 and graceful.* They are swift of foot, and in ordinary seasons 

 feed chiefly on rabbits, both jackrabbits and cottontails, but 

 they also catch ground squirrels and other small mammals, 

 snakes, lizards, birds, and insects, and when put to it by hunger 

 do not hesitate to eat carrion. They are also fond of fruit. 



Unless the contrary is stated, all of the measurements in the 

 present paper were taken ' in the flesh ' by the collector. All are 

 in millimeters.

* It is hoped that no one will be misled, either as to the form or coloring 

 of the Coyotes, by the gross caricature bearing their name in Mivart's re 

 cent ' Monograph of the Canidse.'
