CHAMPA F ASCI ATA AND ITS SUBSPECIES. 

 BY WILFRED H. OSGOOD. 



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

 AFuseum* is a single specimen (No. 3339) winch formed part of 

 the original Baird collection and which is laheled in Prof. 

 Baird's writing ' Pa?-us/ascm<us California, Wm. Gamhel.' This 

 is the only knowm specimen of Cliam/en collected hy Gambel, 

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

 type of Chamxa fnsciata Gamhel. The exact locality from which 

 it came is unknown hut its characters show conclusive!}^ that it 

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

 ern one. This being the case, Chamxa f. henshaivi becomes a 

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

 name for the northern coast form heretofore assumed to be 

 typical fascifda. The status of the two forms may be summa- 

 rized as follows : 



Chamaea fasciata Gambel. Pallid Wren-Tit.
