1874. Ridgway. Am. Sportsman, IV. 1874, 2^1. Re- 

 cords leucosticte atrata taken by Aiken at Colorado Springs. 



1874. Coues. Birds of the Northwest. In addition to a 

 recapitulation of what has been written by Allen and Aiken on 

 Colorado birds, this book contains some long and valuable notes 

 by T. M. Trippe on the birds of Idaho Springs and vicinity. 

 Also several extended notes by J. A. Allen, supplementary to

 Valley, making their headquarters at Fort Garland. The next 

 year C. E. Aiken, as assistant ornithologist of the party, col-
