Observations on the distribution and breeding of birds as noted by the 

 various parties. So far as Colorado is concerned, it is a reprint of the paper 

 rioted above by Mr. Henshaw and all that had been previously written by Mr. 

 C. E. Aiken on Colorado birds, with the addition of much new matter. It gives 

 specific Colorado records for 170 species, of which 14 are here for the first time 

 attributed to the State. The whole makes one of the most valuable contribu- 

 tions to Colorado ornithology.
