CHAMPA FASCIATA AND ITS SUBSPECIES. 

 BY WILFRED H. OSGOOD. 



Among the Wren-Tits in the collection of the U. S. National 

 Museum* is a single specimen (No. 3339) which formed part of 

 the original Baird collection and which is labeled in Prof. 

 Baird's writing ' Parusfasdatus California, Wm. Gambel.' Tin's 

 is the only known specimen of Champa collected by Gambel, 

 and as such Mr. Ridgway has for some time considered it the 

 type of Chamxa fasdata Gambel. The exact locality from which 

 it came is unknown but its characters show conclusively that it 

 belongs to the pale southern form rather than to the dark north 

 ern one. This being the case, Chamssa f. henshawi becomes a 

 synonym of C. fasdata, and it is necessary to provide a new 

 name for the northern coast form heretofore assumed to be 

 typical fasdata. The status of the two forms may be summa 

 rized as follows : 



Chameea fasciata Gambel. Pallid Wren-Tit. 



Pant* fasciatus Gambel, Proc. Acad. Nat. Sci., Phila., p. 265, 1845. 

 Chamsea fasciata Gambel, Proc. Acad. Nat. Sci., Phila., p. 154, 1847. 

 Chamxa fasciata hemhawi Ridgway, Proc. U. S. Nat. Mas., V, 13, June 5, 

 1882. (Type from Walker Basin, California.) 



Type from [southern] California, No. 3339 U. S. Nat. Mus. Collected 

 by Wm. Gambel. 



Distribution. Southern coast and interior of California, including coast 

 valleys and foothills from San Francisco Bay south to northern Lower 



*The Wren-Tits in the U. S. National Museum collection were kindly 

 placed at my disposal by Mr. Robert Ridgway, Curator of Birds.
