larger than in this State, that I suspect he obtained his information from 

 others, instead of by personal observation.

Hab. Central line of Rocky IMountains to the table-lands of Mexico ; Arizona. 



This species is tlie Rocky Mountain representative of C. Stdlcri, from 

 which it differs mainly in tlie liluish-M-hite feathers of the foreliead, the 

 white over tlie eye, and the lonner black crest. In the northern part of 

 the liocky Mountains this jay has its most westward extension, and on the 

 head-waters of the Columbia meets with C. Sfcllcri, and apparently liybrid- 

 izes \\'ith it, as specimens occur there exactly intermediate in character. 



The habits of C. inacrolo2)lms are inueli like those of StdJeri, and the nest 

 and eggs are jjrobably very similar.
