EXTINCT SPECIES. 



The following species have been described by authors, as inhabiting our section, but 

 have not been taken recently anywhere. 



R e g u 1 u s Cuvieri. Cuvier's Kinglet. Similar to the Golden-crown, but has two black bands on crown. A 

 siiiirlc specimen was obtained by Audubon, in June, 1812, in Penn., which has been lost. 



D e n d r 05 c a in o n t a n a. Blue Mountain Warbler. Greenish above and yellow heneath, streaked on breast 

 and sides with dusky. Tail and wings, black. One specimen obtained by Wilson in the Blue Mountains, Vir., years ago. 



Hyiodiootea in i n u t u s . Small-headed Flycatcher. Greenish above, nnd pale yellow beneath, with wings 

 (winded, and outer tail leathers patched, with white. Found by Audubon and others, in the Middle States. There arc no 

 specimen* <>t cither this or the alx>ve now in existence. 



K u s p i z a T o w n s e n d i . Townsend's Bunting. Similar to the Black-throated, but with throat white. One 

 specimen obtained, May 11, 1KJ3, 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, S-75; bill, ra3. A single specimen obtained by Wm. 

 CVmper, at Raynor South, L. I., May 24. 1833. 



Alca i in ii c 11 ii i s . 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. 



Dendrceca carbonata Carb-mated Warbler. Probably a form of plumage of theCape May. 



yKgiothus oanescens. Mealy Rad Poll is what [ consider only a large, p^le fi>rin of linaria. 



1 1 a I i a e t u s Washington!. Washington Eagle, of Audubon. Probably a large specimen of an immature 

 \Vhite-head. 



Lagopus Americanus. This is, doubtless, a plumage of one of our Ptarmigans. 



(Edemia bimaculata. Huron Scoter. A Duck described by Frank Forester, as occurring in number* 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 chalc.opterus. Gray-winged Gull, t'ndouhtedly 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'fX); wing, 17'60. Since writing my article on the Glaucous Gull, a 

 Gull, shot in Bos-ton, April 1, 1H81, 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 Lariiut, "An immature L. 

 g/mtcus 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 hod the bird lived a short 

 time lunger, it would have been pale yellowish-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- 

 inong inemljers 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 y/avcus. My 

 bird is a female, and a careful examinaton of the ovaries shows that it has never deposited an egg, for 1 counted upward of 

 one hundred ovules and could detect no ruptured capsules 



I'uffinus 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. 



U r i a r i n g v i a . Kinged Guillemot. Size and color of the Murre, but has a ring around eye, and line behind it, 

 white. I found these birds mated un Bird llock, 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. 



U r i a a r r a . Thick-bille 1 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 troile.
