The aiitlu'i- had paid special attention to the subject, and published three preliminary- 

 papers in Fr. Phila. Acad., 1862-'3 (q. v.), when the ordering of the Birds of the Northwest by 

 the Government gave him an opportunity of reviewing the case, and of presenting mucli 

 additional matter which had long lain in MSS. The subject was reworked for appear- 

 ance in the present connection, to include full descriptions of the genera and species, full 

 synonymy, extensive criticism, and some considerable anatomical matter. A large number 

 of colored illustrations had been prepared, but it was not found practicable to use them. 

 (N. B. Many of these will probably appear in the last volume of Baird, Brewer, and Ridg- 

 way's History of North American Birds, now (Aug., 1880) said to be about to go to press.
