Prof. Cooke’s ‘Birds of Colorado’* having “led to quite an extensive 
correspondence and in several cases the examination or re-examination 
of large series of specimens.” The new information thus obtained has- 
resulted in increasing the list of Colorado birds from 360, as given in 
Bulletin 371, to 374, a revised summary allotting the fourteen additional 
species to the various categories in which they belong. Additions are 
also made to the ‘ Bibliography of Colorado Ornithology,’ and further 
notes are given relative to the distribution of species previously treated.—
