 BREWSTER'S LIITNET. 



Somewhat like an immature female of A. linaria linaria, but with- 

 out any red on the crown or dusky on the chin, and with portions pi the 

 plumage tinged with sulphur yellow. 



Adult female {male unknown). — Above olive-brownish, streaked with 

 dusky, the rump tinged with pale sulphur yellow, beneath whitish, 

 faintly tinged with dull bufly or pale fulvous on chest, the sides and 

 lower tail-coverts streaked with dusky; wings with two pale fulvous 

 bands across tips of middle and greater coverts; primaries and rec- 

 trices narrowly edged with pale sulphur yellow; wing, 76.20; tail, 

 63.50;' tarsus, 12.70; middle^ toe, 7.62. 



This bird continues to be known only from the type specimen, taken 

 at Waltham, Massachusetts, November 1, 1870, having been shot from a 

 flock of A. linaria. Possibly it is a hybrid of Acanthis linaria and 

 Spinvs pinus.
