18S7-] Brewster on Three New Forms of North Americaji Birds. 1A.K 



monstrates that the Austrian specimens have the bills larger, if 

 anything-, than the average British bird. (Compare tables in Auk, 

 1887, pp. 34, 35.) This table also shows how closely Austrian 

 and British examples agree in general size. 



It is hardly probable that the form inhabiting the mountains of 

 Italy should be different from that breeding in the Austrian Alps, 

 and I therefore now regard A. rufescens as a true synonym of 

 A. cabaret.

THREE NEW FORMS OF NORTH AMERICAN BIRDS. 



BY WILLIAM BREWSTER. 



Mr. J. M. Southwick, of Providence, has called my atten- 

 tion to the fact that western specimens of the Willet differ in 

 size, color, and markings from those of the Atlantic coast. 

 Upon testing these differences by a fairly large series I find the 

 birds of the two regions apparently distinct, at least subspecifi- 

 cally. The western form may be characterized as follows : 



Symphemia semipalmata inornata, subsp. nov. — Western Willet. 



Subsp. Char. Male and Female, breeding plumage : — Differing 

 from 5. semipalmata in being larger, with a longer, slenderer bill ; the 

 dark markings above fewer, finer, and fainter, on a much paler (grayish- 

 drab) ground; those beneath duller, more confused or broken, and bor- 

 dered by pinkish-salmon, which often spreads over or suffuses the entire 

 underparts, excepting the abdomen. Middle tail-feathers either quite 

 immaculate or very faintly barred.
