1 6 Brewster oft BicknelVs Thrush in New England. [January 



found at the highest point where shelter of this kind occurred. 

 There is, of course, no reason for supposing that they are con- 

 fined to the eastern side of Mt. Washington. On the contrary it 

 is highly probable that they are generally distributed over the 

 upper portions of that mountain as well as on many of the higher 

 ones of the surrounding group. Indeed they may be confidently 

 looked for almost anywhere in New England at an elevatio'ii of 

 over 3500 feet. 



Through Mr. Bicknell's kindness I am now able to make a 

 direct comparison between the specimens obtained on Mt. Wash- 

 ington and two of the Catskills examples, one of which (No. 653) 

 figures prominently in Mr. Ridgway's original description of the 

 new race. 



My measurements of these four specimens are as follows : 



653 (E. P. Bicknell) $ ad., Slide Mt., New York, June 15, 1881. Wing, 

 3.65; tail, 2.96; culmen from feathers, .50; from base, .68; depth of bill 

 at nostrils, .16. 



717 (E. P. B.) $ ad., Slide Mt., June 27, 1882. Wing, 3.60; tail, 2.73; 

 culmen from feathers, .54; from base, .67; depth of bill at nostrils, .18. 



7389 (W. B.) $ ad., Mt. Washington, July 20, 1882. Wing, 3.74; tail, 

 2.93; culmen from feathers, .49; from base, .64; depth of bill at nos- 

 tril, .15. 



7390 (W. B.) $ ad., same locality and date. Wing, 3.60; tail, 2.79; 

 culmen from feathers, .52; from base, .67; depth of bill at base, .16. 



The Mt. Washington birds are in worn breeding plumage. 

 They are plain grayish-olive above and along the flanks, with a 

 slight tinge of reddish on the tail, and more or less fulvous over 

 the jugulum and throat. Their general coloring is identical with 

 that of average spring specimens of T. alicice and very much 

 grayer than in Mr. Bicknell's No. 653, which, however, is prob- 

 ably an exceptional specimen, for his No. 717, obtained in the 

 same locality June 27, 18S3, is but a trifle browner than the New 

 Hampshire skins. The latter come well within the limits of size 

 given for bicknelli^ and their bills are fully as slender and de- 

 pressed as in Mr. Bicknell's most extreme specimen (No. 653), 

 This peculiar shape of the bill, already remarked upon by Mr. 

 Ridgway, is a striking point of difference between them and all 

 of a large series of Gray-cheeked Thrushes which I have collected 

 in New England during the migrations. But although seemingly 

 confined to the sinaller race, it is an inconstant character, for Mr. 

 Bicknell's No. 717 has a bill as stout as in many of my largest 

 alicice. Taking size as the sole test (and it is the only one posi-
