and thus, like philadelphicus, is chiefly found as a migrant in tlie U. S. It is not rare, but 

 not so common as oUvaceus, fluvifrons, or noveboracensis ; inhabits woodknd ; a delicious 

 songster. 



v. s. alti'cola. (Lat. alius, high ; colere, to inhabit, or (in)cola, an inhabitant.) Mountain 

 Solitary Greexlet. Like solitariiis proper, but larger, with stouter bill, and darker color- 

 ation ; upper parts nearly uniform dark plumbeous, only tinged with olive on back, instead of 

 being quite olivaceous contrasting whh bluish ash of head. Wing 3.00-3.30; tail 2.25. 

 Mountains of North Carolina, S. in winter to Florida. Brewster, Auk, Jan. 1886, p. Ill ; 

 CouES, Key, 3d ed., 1887, p. 872; A. 0. U. Lists, 1st and 2d eds., 1886 and 1895, No. 629 c. 

 v. s. cas'sini. (To John Cassin.) Cassin's Greenlet.) Like solitarius proper; duller 

 and more brownish-olivaceous ; under parts tinged with buff or ochrey where solitarius is pure 

 white; loral line and eye-ring impurely whitish. "Western U. S., especially the Pacific coast 

 region, in which it breeds from British Columbia southward to Lower California; Arizona, and 

 probably other portions of the Great Basin, where it is associated with V. s. plumbeus, but is 

 not to be confounded with the latter. 



V. s. lucasa'nus. (Lat., of or pertaining to any one named Luke or Lucas; in this case re- 

 ferring to Cape St. Lucas.) Like the last; rather smaller; the bill longer and stouter, the 

 sides and flanks much yellower. Young in autumn resembling that of solitarius proper. Wing 

 2.70; tail 2.00-2.15. Lower California, apparently a very slightly marked form. Brewster, 

 Auk, Apr. 1891, p. 147; A. 0. U. List, 2d ed., 1895, p. 265, No. 62U cl. 

 V. s. plum'beus. (Lat. plumbeus, lead-colored. Fig. 226.) Plumbeous Greexlet. 

 Leaden-gray, rather brighter and more ashy on crown, but without marked contrast, faintly 



glossed with olive on rump; a conspicuous 

 white line from nostril to and around eye, 

 and below this a dusky loral stripe ; below, 

 pure white, sides of neck and breast shaded 

 with color of back ; flanks, axillars, and 

 crissum with a mere trace of olivaceous, or 

 none ; wings and tail dusky, with conspicu- 

 ous pure white edgings and cross-bars. Size

^ ' ^ ■'of solitarius or larger. Length O./O-6.10; 



extent 9.75-10.25; wing 2.90-3.10; tail 2.50; bill 0.50; tarsus 0.66; middle toe the same; 

 spurious quill exposed about 0.75, ^ as long as the 2d quill. Central Plains to the Great Basin, 

 U. S., and especially southern Rocky Mts., where it is abundant ; N. to Wyoming, S. in winter 

 to Oaxaca, Mexico ; accidental in New York. A large stout species, a near ally of solitarius, 

 but nearly all the olivaceous of that species replaced by plumbeous, and the yellowish by 

 white, so that it is a very diflereut-lookiug bird. Fall specimens, however, are more oliva- 

 ceous, and the bird evidently grades closely up to solitarius. 



(Subgenus Vireo proper.) 



V. vici'nior. (Lat. vicinus, neighboring.) Gray Greenlet. With the general appearance 

 of a small faded specimen oi plumbeus : leaden-gray, faintly olivaceous on rump, below white, 

 with hardly a trace of yellowish on sides; wings and tail hardly edged with white; no mark- 

 ings about head except a whitish eye-ring. Length 5.75 ; extent 8.66 ; wing and tail each 

 2.50; tarsus nearly 0.75; middle toe and claw hardly over 0.50; tip of inner claw falling short 

 of base of middle claw ; tail decidedly rounded ; first primary exposed 0.75, ^ as long as 2d 

 primary, which latter is not longer than 8th. These peculiar proportions of the original type- 

 specimen are constant, and the species is distinct from any other. It is our plainest-colored 

 species, resembling 29?»mi>e»s, but more closely allie.l to the suiallor rounder-winged species
