mit [Placer County], and got a specimen July 22." The 

 bird Avas a male, faded and worn; it measured, length, 7.40; 

 extent, 12.10; wing, .3.80; tail, 3.10; tarsus, .15; bill from 

 nostril, nearly .40. It was about fifty feet high in a leafless 

 tree when shot. " This thrush," he further says, " is de- 

 cidedly arboreal, quite as much as Townsend's Solitaire, 

 and like it, goes from the ground well up into the large trees 

 at a sharp angle." 



Mr. Belding has sent me three young birds of Tnrdiis 

 aonalasclikce seguoiensis, which he collected August 12 and 

 27 this year at Lake Tahoe, Cal. They are about full grown, 

 and quite as dark as adults of T. aonalasclikce. Dr. Cooper 

 has hinted that T. a sequoiensis may be but the summer 

 plumage of T. aonalaschkce, bleached out and otherwise 

 changed in the dark but dry woods of the interior; but 

 within a mile of the coast, in Monterey County, where 

 dense fogs prevailed, I found this year birds that were un- 

 like the winter j^lumage of T. aonalasclikce, and referable 

 only to T. a. sequoiensis, although not as pronounced as the 

 type specimens.
