spariiio'ly mixed with black hairs, es^peoially along middle of Ijack ; under 

 ]tai1s wiiite ; no distinct collar (long hairs of throat not noticealdy tipjied

Cranial and denial charQCters. —f^kuW and teeth similar to those of C. 

 latranst, but slightly smaller. The lower premolars and carnassial and 

 the upper carnassial and first molar are decidedly smaller and less swollen 

 than in latrnns. 



Eemarks. — C, jMxUidus is a pale arid-land representative of latran.i. It 

 inhabits the Great Plains fr-om eastern Coloi'ado northward into Canada, 

 and is common throughout Montana except in tlie mountains. On the 

 southern plains, from eastern Colorado southward, it is replaced by 

 another species. Specimens of both have been obtained at Arkins, 

 Colorado. 



Measurements. — Unfortunately we have no flesh measurements of the 

 type specimen, but the hind foot (dry") measures 77 millimeters. The 

 form averages a little smaller than C. lalrans. 



<yant(d measurements. — {^ adult, Johnstown, Nebraska.) Basal lengtli. 

 177; basilar length of Hensel, 17o; zygomatic breadth, 100; palatal

Geograplile distribution. — Transition and Upper Sonoran areas from the 

 Rocky Mountains westward, and from the arid interi(jr of Britisli Columbia 

 (Aschroft, Shnswap) southward over Washington and Oi'egon, and the 

 mountains farther south to the i^lateau region of northern Arizona and 

 New Mexico, and thence southward along the continental divide to the 

 Mexican boundary. In California C. iMcs inhal)its the coast ranges about 

 San Luis Obispo and probably elsewhere, as well as the Sierra Nevada, 

 and in winter it wanders out over the deserts, invading the I'ange of 

 C. est or. 



Oiaracters. — Size large (next to /'(?/'«»s) ; ears and tail large; coloration 

 almost as in latrans ; cranial characters as in pallid us, but skull and teeth 

 averaging somewhat larger.

 front of eyes to ears grizzled gray and ochraceous ; crown, nape, and ears
