EXTINCT SPECIES. 
The following species have been described by authors, as inhabiting our section, but 
have not been taken recently anywhere. 
Regulus Cuvieri. Cuvier’s Kinglet. Similar to the Golden-crown, but has two black bands on crown. A 
single specimen was obtained by Audubon, in June, 1812, in Penn., which has been lost. 
Dendroeca montana. Blue Mountain Warbler. Greenish above and yellow beneath, streaked on breast 
and sides with dusky. Tail and wings, black. One specimen obtained by Wilson in the Blue Mountains, Vir., years ago. 
Myiodioctes minutus. Small-headed Flycatcher. Greenish above, and pale yellow beneath, with wings 
banded, and outer tail feathers patched, with white. Found by Audubon and others, in the Middle States. There are no 
specimens of either this or the above now in existence. — 
Euspiza Townsendi. Townsend’s Bunting. Similar to the Black-throated, but with throat white. One 
specimen obtained, May 11, 1833, near New Garden, Penn. None have been seen since. 
Tringa Cooperi. Cooper’s Sandpiper. Bill, straight. Ashy above, and white beneath. Upper tail cov¬ 
erts, white with V-shaped marks of black. Length, 9 - 50; wing, 5 - 75; bill, 1'23. A single specimen obtained by Win. 
Cooper, at Raynor South, L. I., May 24. 1833. 
Alca impennis! Great Auk. Form of Razor-bill. Above, black, with large spot in front of eye, and be¬ 
neath, white. Length, 30’00; wing, 5*50. Formerly abundant on our coast, but last seen thirty-eight years ago. 
DOUBTFUL SPECIES. 
Myiodioctes Bonaparti. Bonaparte’s Flycatcher. Probably the young of M. Canadensis. 
Dendroeca carbonarta Carbonated Warbler. Probably a form of plumage of the Cape May. 
iEgiothus canescens. Mealy Red Poll— is what I consider only a large, pale form of linaria. 
Ilaliaetus Washingtoni. Washington Eagle, of Audubon. Probably a large specimen of an immature 
White-head. 
Lagopus Americanus. This is, doubtless, a plumage of one of our Ptarmigans. 
QEdemia bimaculata. Huron Scoter. A Duck described by Frank Forester, as occurring in numbers on 
Lake Huron, during fall and winter, which has a bill like that of the Surf Duck, but is black. The plumage is also black 
with spot in front of eye, and patch on wing, white. It is a matter of question, as to what this species is, for no one ap¬ 
pears to have taken it since. 
Larus chalcopterus. Gray-winged Gull. Undoubtedly the young of the White-wing. 
Larus cuculatus. Hooded Gull— is the young of Franklin’s Gull. 
Pagophila brachytarsi. Short-legged Gull. This is, without doubt, an Ivory Gull with shorter tarsi 
than usual. 
Larus Hutchinsi. Hutchins’ Gull. White, no pearly mantle, but mottled with pale yellowish-brown on 
neck, back, and under tail coverts, and more faintly on tail; tinged beneath with a darker shade of the same, while the 
bill is pinkish, tipped with dusky. Length, 26 00; wing, 17'60.- Since writing my article on the Glaucous Gull, a 
Gull, shot in Boston, April 1, 1881, answering to the above description, has come into my possession, and I should unhesi¬ 
tatingly pronounce it, as remarked by Mr. Howard Saunders in his incomparable Work on the Larince, “An immature L. 
glaucus in the stage where the mottled brown of the immature stage has passed away and the pearly gray mantle has not 
begun to show”, were it not for the fact that it is moulting, and the new feathers indicate that had the bird lived a short 
time longer, it would have been pale vellowish-brown banded and mottled with darker, excepting on wings and tail which 
not being moulted in the spring, would have remained pure white. This presents a change of plumage quite unique a- 
mong members of this Family, where none are described as passing from a pale winter dress to a darker one in summer, and 
if it does not re-open the question of the validity of Hutchinsi, certainly shows a new phase of plumage for glaucus. My 
bird is a female, and a careful examinaton of the ovaries shows that it has never deposited an egg, for I counted upward of 
one hundred ovules and could detect no ruptured capsules. 
Puffinus fuliginosus. Sooty Shearwater. Size of Greater, but sooty-brown throughout, lighter beneath. 
Although considered by nearly all writers, as a species, it may prove to be the young of the Greater Shearwater. 
Uria ring via. Ringed Guillemot. Size and color of the Murre, but has a ring around eye, and line behind it, 
white. I found these birds mated on Bird Rock, among thousands of Murres, there being, however, only about one pair 
of the Ringed to every hundred of the others, and"consider that they have a good claim to specific rank, though they are 
not so regarded by ornithologists generally. 
Uria a r r a . Thick-billed Guillemot. Similar to the Murre, but with bill stouter and colors darker. I do not 
consider this a species, as 1 am confident that I have seen all gradations between it and Iroile.
