DESCRIPTION OF A NEW THRUSH. 19 



wing measurement of 3.75 inches, and although in worn 

 breeding plumage, is otherwise quite as large as the above 

 described male. 



The only nest found was in a liazel bush {Corylus) about 

 three feet from the ground; was about five inches across 

 the top and about half as deep; composed of small roots 

 and lined with shreds of the bark of incense cedar (Libro- 

 cedrus), with moss, lichens and dead leaves on the exterior. 



The nest contained two quite fresh eggs; thej were un- 

 spotted, nearly the color of a robin's egg and measured 

 .85 X 65 ; .83 x .63 inches. I shot the female parent as she 

 flew from the nest, kept lier and the nest, but sent the eggs 

 to Mr. Chas. N. Comstock, who- had previously found the 

 nest. I informed him that they were the eggs of the dwarf 

 thrush and he published them as such. 



I attributed the paleness of this and other individuals I 

 saw occasionally here, in summer, during the past ten years 

 or more, to lateness of the season, but on June 10, 1888, I 

 shot a male in good plumage and concluded that it was 

 worthy of varietal or specific rank, and a recent comparison 

 of specimens of this with specimens of T. aonalascJikcej 

 T. aoncdaschJcce auduhoni, T. aoncdaschJcos j)cillasii and others, 

 mostly furnished by the kindness of Prof. Eobert Ridgway 

 from the National Museum, convinces me that it is entitled 

 to the latter. 



The absence of olive and almost entire absence of buff 

 from its plumage together with its paleness, distinguishes 

 it at once from any of the small thrushes of America. Ex- 

 cept for the cinnamon of the tail it most resembles a faded 

 alicice from Alaska. The faqt of its laying eggs like tliose 

 of aonolaschkce, auduhoni and ixdlasii and having the rufous 

 tail of these forms does not establish the other fact that it 

 is but a variety of these. 



Habits and songs, especially the latter, may go far to- 

 wards fixing its true relationship.
