DESCRIPTIONS OF SEVEN NEW SUBSPECIES OF 

 AMERICAN BIRDS.

The seven birds herein described as new subspecies are from 

 material that has accumulated in the Bangs collection, from 

 various sources, during the past few years. The descriptions 

 have been prepared from time to time and are now published 

 together to avoid the inconvenience of a number of short 

 articles.
