76 PICID.E I WOODPECKERS. 



WHITE-BACKED THREE-TOED WOOD- 

 PECKER. 



PICOIDES AMERICANUS Brehm. 



Chars. With only three toes like the last, and quite the same 

 coloration, excepting a white lengthwise stripe down the back, 

 which is interrupted by black bars. Size of the last. 



This is a second species of the mutilate Woodpeckers 

 one whose range is intrinsically the same as that of 

 its amputated congener, but whose winter wandering, as 

 far as known, is not as extensive as the Black-back's. 

 There is no record for the Carolinian Fauna that I am 

 aware of, and there are very few for the Alleghanian, 

 though the bird is now and then seen in Massachusetts 

 as a winter visitor from the north. Even in the forests 

 where it resides it is a rarer bird than P. arcticus. The 

 principal authority for its occurrence in Massachusetts 

 is Mr. Allen, who mentions a pair taken near Lynn by 

 Mr. George O. Welch (Am. Nat., iii, 1870, p. 572).

 SPHYROPICUS VARIUS (L.) Bd.

 breast black, enclosing a crimson patch on the former (which is 

 white in the female) ; sides of head with two white stripes, one 

 curving from the eye around the nape, the other running from 

 the bill down the side of the neck, these stripes separated by 

 black, and sometimes decidedly yellowish, instead of white ; belly 

 yellowish ; sides with dusky arrow-heads ; back variegated with 

 black and yellowish ; wings black, the quills profusely spotted
