V. h. obscu'rus. (Lat., obscure.) Obscure Greenlet. Anthony's Yireo. The dark 

 fi)rin of V. huUnni from the Pacific coast regiou, breeding in British Columbia, Washington, 

 and Oregon, and migrating S. in winter. Anthony, Zoe, i, Dec. 1890, p. 30(J; A. 0. U. 

 List, 2d ed., 1895, p. 266, No. 632 c; not in any previous ed. of the Key. 

 V. h. ste'vensi. (To F. Stephens.) Stephens' Greenlet. Like V. huttoni. Bill stout; 

 wino-s 0.30-0.40 longer than tail. Above, grayish-ash ; crown, vertex, and sides of head and 

 neck nearly pure ash; back faintly tinged with olive; rump and edging on tail-feathers dull 

 olive-green. AVings with two nearly confluent bauds on coverts, and outer edges of inner 

 secondaries broadly white ; outer quills edged more narrowly with the same color. Beneath 

 brownish or smoky-white, with a mere wash of yellowish on sides and crissum. Upper eyelid 

 dusky-browu : remainder of orbital region, with lores, ashy-white in decided contrast with the 

 nearly clear cinereous vf tlie head generally. Lining of wings white. Length 5.20 ; extent 

 8.50; wing 2.55-2.90; tail 2.25; tarsus 0.73; culmen 0.50. Lower California, Arizona, and 

 New Mexico, especially in mountain ranges. Related to huttoni, which has bill less stout, 

 wing 2.40 0)- less, and is olive-green above and olivaceous-yellow below, without clear white 

 anywhere. The differences are nearly parallel with those between belli and pusillus, — 

 sterensi being grayish-ash above with no decided olive-green excepting on rump and tail, 

 brownish-white below, untinged with yellowish excepting on sides and crissum, the wing- 

 bands pure white and nearly confluent. (Not in Check List, 1880. Description from Brews- 

 ter, Bull. Nutt. Club, vii, July, 1882, p. 142.) 



V. belli. (To J. G. Bell, of New York. Fig. 229.) Bell's Greenlet. Olive-green, 

 briiihter on rump, ashier on head, but without decided contrasts ; head-markings almost ex- 

 actly as in gilvus ; below, sulphury-j-el- 

 lowish, only whitish on chin and middle of 

 belly ; inner quills edged with whitish ; 

 two whitish wing-bands, but one more 

 conspicuous than the other. Hardly or 

 not 5.00 long ; wing scarcely over 2.00 ; 

 tail under 2.00 ; spurious quill about | the 

 2d, which equals or exceeds the 7th. A 



V. belli, nat. size. (From Baird.) 



like a miniature of gilvus, but readily distinguished from that s})ecies by 



pretty little species 



its small size, presence of decided wing-bars, more yellowish under-parts, and different wing- 

 formula. Middle region of the U. S., W. to the Rocky Mts., E. to the valley of the Ohio, N. 

 to the valley of the Red River in Minnesota and Dakota ; an abundant species, inhabiting 

 copses and shrubbery in open country, with much the same sprightly ways and loud song as 

 those of noveboracensis. Nest in bushes; eggs 0.67 X 0.48. 



v. b pusillus. (Lat. 2»isillus, puerile, petty. Fig. 230.) Least Greenlet. Olivaceous- 

 gray, below white, merely tinged with yellowish on sides ; head-markings obscure ; wing- 

 bands and edgings, though evident, nar 



row and whitish ; no decided olive or yel- 

 low anywhere. Size of belli ; wing and 

 tail of equal lengths, little over 2.00 ; bill 

 0..33; tarsus 0.66; middle toe and claw 

 0.50 ; spurious quill about ^ as long as 2d, 

 which is intermediate between 7th and 

 8th. A small, obscure-looking bird, re- 

 sembling belli, but much grayer, tail relatively longe 

 shorter. Questionably right to reduce this to a subspecies of belli, for the difference is obvi- 

 ous at a glance, and more decided than that separating most of the subspecies. It has held 

 specific rank in all previous editions df tlif Key. Arizona and Southern and Lower California ;
