58 CALIFORNIA MAMMADS. 



Rocky Mountains to Sierra Nevada and Cascade Mountains 

 and intervening ranges. In California Rocky Mountain Big- 

 horns were formerly found in parts of the Sierra Nevada and 

 on Mount Shasta, but they are apparently now exterminated in 

 those mountains. It is possible that these animals were not 

 canadensis, but were nelsoni or some unnamed form. Material 

 is lacking now to determine this point, with little probability of 

 more being obtained. Two or three very small bands still exist 

 in certain mountains of southwestern California that are prob 

 ably intermediate between the above species and nelsoni. Poach- 

 ers are destroying them and their destruction is probable in a 

 few years.

 Nevada, southeastern California, the northeastern border of 

 Lower California and probably western Arizona. An adult male 

 Nelson Bighorn in good condition will weigh two hundred and 

 fifty pounds and a female one hundred and fifty. They prefer hillv
