yellowish green ; the outer web of outer feather white instead of a large spot on the inner weh. 

 Tlie back appears more distinctly streaked. 



The Carbonated Warbler is only known by the description and figure of Mr. Audubon, taken 

 from two specimens killed at Henderson, Kentucky, in 1811. The indications are not sufficient 

 to show in what particular group of warblers it is to be placed.

Sp. Ch. — Head above chestnut red ; rest of upper parts brownish olive gray ; the feathers with darker centres, the color 

 brightening on the rump, upper tail coverts, and outer margins of wing and tail feathers to greenish yellow. A streak from 

 nostrils over the eye, and under parts generally, including the tail coverts, bright yellow ; paler on the body. A maxillary 

 line ; breast and sides finely but rather obsoletely streaked with reddish brown. Cheeks brownish, (in highest spring plumage, 

 chesnut like the head) ; the eyelids and a spot under the eye, olive brown. Lores dusky. A white spot on the inner web of the 

 outer two tail feathers at the end. Length, 5 inchrs ; wing, 2.42; tail, 2.25. 



Hab. — Eastern United States to the Mississippi, and Red river of the North. 



Without a very good series of specimens before me, I am unable to give a complete 

 description of the species. None are marked for sex, but skins supposed to be females differ 

 chiefly in a less amount of chestnut on the crown. There is no clear indication of any bands 

 on the wing, although the edges of the coverts are slightly paler. 



An autumnal male (783) shows a strong tinge of reddish in the olive brown of the back, and 

 the chestnut of the crown is much concealed. The under parts are of a very vivid yellow 

 throughout, obscured by brown. The axillaries are yellow. As in other specimens, the outer 

 web of the first tail feather is whitish on the under surface. In this the tail is nearly even, 

 slightly emarglnate ; the second and third quills longest ; the first shorter than the fourth. 

 The size appears unusually large. Length of skin, 5.20 ; wing, 2.75 ; tail, 2.50. 



In one specimen there is scarcely any yellow about the head and neck, this color being replaced 

 by dirty white ; the crown streaked with btown. 



This species in its immature state bears some resemblance to D. tigrina, but is distinguishable 

 by the chestnut crown, browner back, less vivid yellow of the rump, much brighter yellow of 

 under tail coverts, smaller blotches on the tail feathers, absence of white bands on the wings, &c. 



It is almost certain that the present species is not the ilotacilla petechia of Linnaeus, as quoted 

 by authors. The diagnosis of Linnaeus, M. olivacea, suhtus flava ruhro guttata, pileo ruhro, 

 applies much better to the red crowned variety of D. aestiva than to the present bird. The 

 fuller description of Pennant (Arctic Zool. II, 401) says, " crown scarlet, cheeks yellow, hind part 

 of neck, back, and rump olive green ; wings and tail dusky, edged with yellow ; beneath rich 

 yellow speckled with red, except the vent, which is plain." Vieillot describes Sylvia petechia in 

 much the same words, and adds that the tail feathers are brown, margined with yellow, which 

 extends furthest in on the inner web. This totally ignores the white terminal spots. Tiie 

 S. palmarum is described in detail by Vieillot, and is undoubtedly the present bird.
