A SYNOPSIS OF THE GENUS THRYOMANES 



BY HARRY C. OBERHOLSER 



Since the publication of the writer's revision of the 

 genus Thryomancs/ additional data concerning the geo- 

 graphic distribution, status, and relationships of several 

 of the forms have been accumulating. Some of these have 

 already been published by- Mr. H. S. Swarth, in his excel- 

 lent article on the Pacific Coast races of Thryomanes he- 

 wickii,- and by Mr. Robert Ridgway in his treatment of the 

 genus in the " Birds of North and Middle America." ^ The 

 remainder we purpose to present here, together with, for 

 convenience, a brief synopsis of all the forms of the 

 genus, including a revision of their geographic distribu- 

 tion. For detailed descriptions and comparisons the three 

 contributions above mentioned should be consulted. We 

 are much indebted to Dr. J. Grinnell and Mr. H. S. Swarth 

 for the loan of material from the Pacific coast region. 



The genus Thryomanes at present consists of four 

 species, one of these, Thryomanes bewickii, comprising 16 

 geographic races, one of which we are here describing as 

 new.
