entirely yellowish. CaJifomia. First quiU ratiier less than half the 2d, which about equals 

 the 10th; 3d a little longer than 7th; 4th and 5th nearly equal and longest. Tail slightly 

 rounded, shorter than the wings. BiU very small. Above oUve-green; brightest behind, 

 especially on rump and edging of taU; duller and more 

 ashy toward and on top and sides of head and neck. 

 Wings with two bands on coverts, and outer edges of 

 innermost secondaries rather broadly olivaceous-white; 

 other quills edged externally with olive-green, paler 

 toward outer primary, internally with whitish. Lat- 

 eral tail-feathers edged externally with yellowish- 

 white. Feathers of rump with much concealed yel- 

 lowish-gray. Under parts pale olivaceous-yellowish, Fio.iss—^-- A»«o«i,nat. size. (From Baird.) 



purest behind, lightest on throat and abdomen ; the breast more olivaceous, the sides stiU 

 deeper olive-green, the breast soiled with a slight buflfy tinge. Axillars and crissum yellowish, 

 the inside of wings whitish. Loral region and narrow space around eye duU yellowish, in faint 

 contrast to the olive of head. Bill horn-color above, paler below ; legs dusky. Length 4.70 ; 

 wing 2.40 ; tail 2.05. (Description from Baird.) 

 182a. V. h. ste'vensi. (To F. Stephens.) Stephens' Grbenlet. Like V. huttoni. Bill stout ; 

 wings from 0.30-0.40 longer than tail. Above, grayish-ash ; the crown, vertex and sides of 

 head and neck nearly pure ash; the back faintly tinged with olive; the rump and an edging on 

 the tail-feathers duU olive-green. Wings with two nearly confluent bands on the coverts, and 

 the outer edges of the 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 the sides 

 and crissum. Upper eyelid dusky- brown; remainder of the orbital region, with the lores, 

 ashy-white ia decided contrast with the nearly clear cinereous of the head generally. Lining 

 of wings white. Length 5.20; extent 8.50; wing 2.55-2.90; taU 2.25; tarsus 0.73 ; eulmen 

 0.50. Arizona and New Mexico, especially in mountain ranges. Related to huttoni, which 

 has biU less stout, wing 2.40 or less, and is olive-green above and olivaceous-yellow below, 

 without clear white anywhere. The differences are nearly parallel with those between belli and 

 pusiUus, — steoensi being grayish-ash above with no decided oKve-green excepting on the rump 

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

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

 Brewster, BuU. Nutt. Club, vii, 1882, p. — .) 

 183. V. beVU. (To J. G. BeU, of New York. Fig. 200.) Bell's G-eeenlet. Olive-green, 

 brighter on rump, ashler on head, but without decided contrasts ; head-markings almost 

 exactly as in gilvus; below, sulphury-yellowish, only whitish on chin and middle of belly; 

 inner quills edged with whitish ; two 



whitish wing-bands, but one more con- 

 spicuous than the other. Hardly or not 

 5.00 long ; wing scarcely over 2.00 ; tail 

 under 2.00 ; spurious quUl about f the 2d, 

 which equals or exceeds the 7th. A pretty 

 little species, like a miniature of gilvus, but 

 readily distinguished from that species by ^-lo. 200. - r. belli, nat. size. (From Baird.) 



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 ; an 

 abundant species, inhabiting copses and shrubbery in open country, with much the same 

 sprightly ways and loud song as those of noveboracensis. 

 184. V. pusil'lus. (Lat. pusiUus, puerile, petty. Fig. 201.) Least Greenlet. Olivaceous- 

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