I name this unique specimen in honor of Prof. A. Duges from 

 whom it was received by the National Museum. 



Through the courtesy of Prof. Ridgway I have recently ex- 

 amined the extensive series of Golden Warblers in the col- 

 lection of the National Museum, and the two new races described 

 above are the result. My acknowledgements are also due to Mr. 

 H. W. Henshaw for allowing me to use his specimens for com- 

 parison. 



♦Length taken from a dried skin. 

 *Sex not marked, but evidently a male.
