GEN. 36. 105 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 : 5J 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 vigorsii Nutt., i, 318 ; S. pinus WiLS., iii, 25, pi. 19, f. 4; Nutt., i, 387 ; AuD., ii, 371, pi. 82; Bd., 277 pinus. Obs. The two following species, ascribed to North America, are not now known:— Blue Mountain Warbler. Sylvia Montana Wils., v, 113, pi. 44, f. 2 (Blue Mountains of Virginia). Aud., ii, 69, pi. 98 (" California"). Bd., 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 ; Mr. Turnbull (Birds of New Jersey, p. 18) says, without qualification, it is the young of D. ccerulea. 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,
