Var. Fuscescens. Dusky Redpoll. (Puiare it, figs. 3, 3a.) Upper parts nearly 
uniform dusky, rump scarcely lighter, sides heavily streaked; bill dusky. Avp., 
iii, pl. 179? Cowes, Proc. Phila. Acad., 1861, 222, 390; 1869, 186; Extror, pl. 10. 
I am not sure that this is anything more than a state of plumage of linarius, as the 
dusky appearance may be due to wearing away of the lighter edges of the feathers. 
Var. exttires. American Mealy Redpoll. (Puiare m1, figs. 6, 6a.) Colors pale, 
the flaxen of linarius bleaching to whitish ; rump white or rosy, entirely unstreaked 
in the adults; breast pale rosy, and streaks on the sides small and sparse; bill 
very small, with heavy plumules ; feet small, the middle toe and claw hardly or not 
equal to the tarsus. Avp., iii, 120, pl. 178; Cours, Proc. Phila. Acad., 1861, 385, 
1869, 187; Extror, pl. 9. An Arctic race, not difficult to recognize, representing 
in America the true Mealy Redpoll, A. canescens, of Greenland. 
Oss. In addition to the foregoing, a large variety with a very large yellow bill, 
apparently corresponding to what is called holbclli in Europe, has been noted from 
Canada. Couvegs, Proc., Phila. Acad., 1862, 40; 1869, 184. 
6lbis. Genus LINOTA Bonaparte. 
Brewster's Linnet. With the general appearance of an immature Aegio- 
thus, this bird will be recognized by absence of any crimson on the crown, a 
peculiar yellowish shade on the lower back, and somewhat different propor- 
tions. Massachusetts, one specimen (Lrewster). Aegiothus flavirostris, 
var. brewsterii Ringway, Am. Nat. vi, July, 1872. An interesting dis- 
covery, of which I learn as these pages go to press; may be same as the 
European. (Notin the Key.) . . . ‘JFLAVIROSTRIS var. BREWSTERII.

*Sexes alike. Bill extremely acute; nasal plumules sometimes deficient. 
Everywhere thickly streaked ; no definite black on head ; no red anywhere. 
Pine Linnet. (Puate ut, figs. 11, lla, 12,12a.) Continuously streaked 
above with dusky and olivaceous brown or flaxen, below with dusky and 
whitish, the whole plumage in the breeding season more or less suffused 
with yellowish, particularly bright on the rump; the bases of the quills and 
tail feathers extensively sulphury yellow, and all these feathers more or 
less edged externally with yellowish. 43; wing 22; tail 12; forked. The 
plumage is extremely variable; young birds frequently show a buffy or 
flaxen suffusion, and resemble a redpoll; but the yellowish coloration of 
the wings and tail is peculiar, and distinctive of the species. North Amer- 
ica, breeding northerly, ranging throughout most of the United States, in 
flocks, in the winter; abundant. WHd1s., ii, 133, pl. 17, f.1; Nurv., i, 511;
