 ages of North American Birds." He discussed the plumages 

 of common birds that were not very well known, such as

 trating his remarks with a series of skins.

 lected. Robin (Merula migratoria), jNIyrtle Warbler (Dendroica 

 coronata), Tree Sparrow (Spizella monticola) and Snowflake 

 (Passerina nivalis) were the only other land birds observed.

 borealis) in Prospect Park, Brooklyn, on January 7. 



Mr. B. S. Bowdish spoke of the continued abundance of 

 Myrtle Warblers this winter at his home in Demarest, N. J. 

 Their presence, it was thought, was due to the mildness of the

 Meadowlarks {Sturnella magna), as attested by the observa- 

 tions of Messrs. Bowdish, Weber and Abbott.
