111. D. aestl'va. (Lat. cestiva, summery ; (Estas, summer.) Summer Warbler. Summer Yel- 

 low-bird. Blue-eyed Yellow Warbler. Golden Warbler. g, adult: Golden- 

 yellow ; the back with a greenish tinge resulting in rich yello\y-olive, the rump more yellow- 

 ish ; the middle of the hack sometimes ohsoletcly streaked with darker. Crown like the under 

 parts, in high plumage often tinged with orange-brown. Breast and sides, and sometimes 

 most of the under parts, streaked with orange-brown. Quills and tail-feathers dusky, edged on 

 both webs with yellow, the yellow occupying most of the inner webs of the tail-feathers. Bill 

 plumbeous. Feet pale brown. Length i. 75-5. 00; extent 7.50-7.75; \ring 2.50; tail 2.00. 

 9 , adult : Yellow-olive of upper parts extending on the croMTi ; streaks below obsolete or 

 entirely wanting. General coloration paler. Young : Like the 9 i l"it still duller colored. 

 Upper parts, including crown, pale olive, with an ochrey instead of clear yellow shade ; 

 below ochrey-white or dull pale yeUoM'ish. Edgings of wings and tail dull yellowish. North 

 Aijierica, everywhere in woodland, gardens, orchards, parks, and even city streets, a beautiful, 

 abundant, and familiar little bird. Kests throughout its range, in fruit or shade trees, shruli- 

 bery and brushwood, building a neat, compact, and durable nest of soft vegetable and aniuuil 

 substances felted together; eggs commonly 4-5, from 0.64 to 0.60 X 0.48 to 0.53, grayish- or 

 greenish-white, variously dotted and blotched with reddish-brown and lilac shades. The color 

 of this precious gem makes a pretty spot as it flits through the verdure of the forest or plays 

 amidst the rose-tinted blossoms of the fruit-orchard ; and its sprightly song is one of the most 

 familiar soitnds of bird-life during the season when the year renews its youth. 

 Ilia. B. vieil'loti bry'anti. (To L. P. Vieillot. To Dr. Henry Bryant.) Chestnut-headed 

 Golden Warbler. Belonging to the " golden warbler " group of the genus, and resembhng 

 D. cestiva in general characters. Dusky predominating over yellow on the tail-feathers ; 

 tarsus about 0.72. <J, adult: Whole head chestnut, well deiined all tiround against the 

 yellow ; edging of wing-coverts slight ; rufous streaks of breast and sides few and narrow. 

 Tlie continental D. vieilloti, as described by Cassin in 1S60, would appear to be well dis- 

 tinguished among its immediate insular allies l)y the rufius hood which envelopes the head, 

 but to be very questionably divisible into the several forms noted by Eidgway in 1S74. That 

 here given is described as the Mexican race, lately ascertained to occur at La Paz, Lower 

 California. The $ is said to be indistinguishable fr(im that of others of the golden warbler 

 group. The extra-hmital forms ai-e all said to difler from the N. Am. S. cestiva in having 

 longer tarsi and less yellow on tlio tail-feathers. (Not in the Check List, 1883. See Hist. 

 N. A. Birds, i, 1874, p. 217, and Pr. U. S. Nat. Mus., iv, 1882, p. 414.)

 (J, in spring : Back and crown clear yellow-olive; forehead, superciliary line, and whole sides
