and the Tiirdus alicice are the same. In a conversation with 

 Professor Baird, since the issue of Allen's paper, I was in- 

 formed, that, in a large suite of specimens of both species, 

 to which he had access, he could identify each by character- 

 istics so fixed that any confusion was impossible : he was 

 of the opinion that Mr. Allen had not seen the bird Jie calls 

 alicice. I have therefore not given that species as a bird of 

 New England, and think that it 7/et remains to be proved as 

 such. 



Dr. Bryant, in describing the habits of the Olive-backed 

 Thrush, says : — 



" Its note differs entirely from that of T. paUasii, and the birds 

 also differ very much in their habits ; the hitter species being gen- 

 erally seen on the ground, while the Olive-backed Thrush prefers 

 to procure its food among the branches. The one seen at Big Mud 

 Lake, Grand Manan, was perched on the top of a small dwarf-fir, 

 and was hunting the passing insects with all the dexterity of a 

 typical Flycatcher."

It is very seldom that specimens exhibit the colors exactly as described. Nearly 

 always in winter, and in most cases at other times, the rufous feathers are margined 

 with whitish, sometimes quite obscuring the color. The black feathers of the head,
