WEST [NDIES 



By J. II. RILEY 



While examining a small scries of Myiarchus oberi Lawrence in 

 the United States National Museum, 1 was impressed by the differ- 

 ences between specimens from Grenada and St. Vincent on the one 

 hand and Dominica and Santa Lucia on the other. As the type of 

 Myiarchus oberi came from Dominica, the Grenada and St. Vincent 

 form may be known as : 



MYIARCHUS OBERI NUGATOR subsp. nov.

 Grenada, W. I., March, 1878. Collected by F. A. Ober.

 and middle wing-coverts and tertiajs broadly edged with white, and 

 upper tail-coverts without rufous edgings.
