DESCRIPTION OF A NEW THRUSH FROM CALAVERAS 

 COUNTY, CALIFORNIA. 



BY L. BELDING. 



Turdus sequoiensis, sp. nov. 

 Big Tree Thrush. 



Sp. char. — In size between the Dwarf and Audubon's 

 Thrushes. In color paler than either or any American 

 thrush I have ever seen; both above and below considerably 

 resembling T. aliciw, the spotting included, while its cheeks 

 are still grayer than in alicice. Tail and coverts about as 

 light cinnamon as in T. auduhoni. Lores, superciliary, or- 

 bital ring and under parts pure white; sides and flanks pale 

 brownish white or ashy, a very slight trace of yellow on the 

 the breast; a tinge of buff in the band on under side of 

 wing, this band being nearly pure white. Exposed parts 

 of primaries much lighter than back; inner webs of quills 

 brownish. Feet and tarsi very pale in fresh specimens. 

 First quill longer than the fifth and shorter than the fourth; 

 second and third about equal. Terminal inch or more of 

 outer web of second, third and fourth primaries, attenuated, 

 in this agreeing with the Dwarf and Audubon's Thrushes, 

 and disagreeing with T. nstulatus and its varieties.
