markings whatever, except the superciliary line; and by the combination of 
white wing-bars with large oblique tail-spots confined to the two outer pairs 
of feathers. One of the largest species: 54 to nearly 6. Eastern United 
States, very abundant in pine woods and cedar thickets; has an extensive 
breeding range, and is apparently resident in southern portions. Vireo

known :— 
Blue Mountain. Warbler. Sytv1a montana Wits., v, 113, pl. 44, f. 2 (Blue 
Mountains of Virginia). Aup., ii, 69, pl. 98 (‘ California”). Bp., 278. Professor 
Baird suggests that some plumage of D. pinus or striata may furnish the clue to 
this lost species; but these are among the largest warblers, whilst Wilson says 
“length four inches and three-quarters.” Mr. Turnbull (Birds of New Jersey, p 
18) says, without qualification, it is the young of D. cerulea. I think myself that 
it is simply the young of D. virens! of which, it seems, Wilson never recognized 
an autumnal example. A September specimen of virens, before me as I write, 
agrees almost precisely with Wilson’s description — rich yellow olive; front, cheeks, 
chin and sides of neck, yellow; * * two exterior tail feathers white on the 
inner vanes from the middle to the tip, and edged on the outer side with white, etc. 
Now D. virens is the only Eastern species, showing this latter feature, that agrees 
with the other assigned characters at all. It is curious additional evidence that I 
am right in this surmise, that the original of Audubon’s figure, in the British 
Museum, came from ‘California;” for I suppose that this specimen was the 
young of occidentalis or townsendii, some of the plumages of which, as well as can 
be made out, are with difficulty distinguishable from immature virens. 
Carbonated Warbler. Sytvra cARBonatTa Aub. Orn. Biog. i, 308, pl. 60; Norr., 
i, 405; Avp., ii, 95, pl. 109; Bp., 287. Only known by the figure and description 
of a pair killed in Kentucky. I have no idea what this is; it may not be a 
Dendreca at all. Audubon himself put it among the worm-eating warblers. 
36. Genus SEIURUS Swainson. 
*,* The birds of this genus have been classed with the thrushes, and also with 
the titlarks (which they somewhat resemble in habits, being walking birds), but 
they have no special affinity with either. They are simply terrestrial warblers, 
closely related to gen. 37, 38. Five species are 
enumerated, but the exotic representatives of nove- 
boracensis and ludovicianus seem to be mere vari- 
eties. 
* Crown orange-brown, with two black stripes ; no 
superciliary line. 
Golden-crowned Thrush. Oven Bird. Bright 
olive green; below pure white, thickly spotted 
with dusky on breast and along sides; a narrow 
maxillary line of blackish; under wing coverts 
tinged with yellow; a white eye-ring; legs flesh color; wings and tail 
unmarked. Sexes alike; young similar. Length 54-64; wing 3; tail 23.
