EXTINCT SPECIES. 



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

 have not been taken recently anywhere. 



Rpo-ulus Cuvieri. Cuvier's Kinglet. Similar to tlie Golden-crown, but hits two black bands on crown. A 

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



Dendrceca 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., yeai-s ago. 



M \ i o d i c t e s in i n ut u s . Small-headed Flycatcher. Greenish above, and pale yellow beneath, with wings 

 nanded, and (.liter tail featliers patched, with white. Found by Audubon and others, in the Middle States. There are no 

 specimens of eirher this or the above now in existence. 



E 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 

 si)ecimen obtained. May 11, 1833, near New Garden, Penn. None have been seen .since. 



T r i □ •; a C o o |) e r i . Cooper's Si^ndpiper. Bill, straight. Ashy above, and white beneath. Upper tail cov- 

 erts, wiiite with V-shaped marks of black. Length, 950; wing, 5-75; bill, |-23. A single specimen obtained by Wm. 

 Cooper, at Raynor South, L. I., May 24. !833. 



.V 1 a i lu 1) e n n i s , Great Auk. Form of Razor-bill. Above, Mack, with large spot in front nf eye, and !»- 

 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 

 1) e n d r oe c a c a r b o n a t a Carbonated Warbler. Probably a form of plumage of the Cape May. 



Lin Ota Brewsteri. Brew.ster's Linnet. Form and size of Red Poll, but lacks the crimson crown. Only a 

 single specimen has I)eea obtained, by Mr. Brewster at Concord, Mass., a few years ago. 



11 c 1 m i M t h o p h aga C i n c i n n a t i e n s i s . Cincinnati Warbler. Greenish above; yellow beneath, patch 

 before eye and on ear and line on sidesof crown, black. Length, 4-75; wing, 2-50: tail, 1-8.5. A single specimen obtained 

 by its de-;criber, F. W Langdon, at Madisonville, Ohio, May, 1, 1880. 



llaliaetus Washingtoni. Washington Eagle, of Audubon. Probably a large specimen of an immatui-c 

 {V bite-head. 



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



ffidemia 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 chaleopterus. Gray-winged Gull. Undoubtedly the young of the White- wing. 



Larus ouculatus. Hooded Gull— is the young of Franklin's Gull. 



Pa g o p h i 1 a b r a-c h y t a r s i . Short-legged Gull. This is, without doubt, an Ivory Gull with sliurter tarsi 

 than usual. 



Larus H u t li i n s i . Hutchins' Gull. White, no pearly mantle, but mottled with pale yellowish-brown on 

 neck, back, and under tail cuverts, and more faintly on tail; tinged beneath with a darker shade of the same, while the 

 bill is pinkish, tipped with dusky. Length, 26 1)0; wing, 17'60. Since writing my article on the Glaucous (_iul!, a 

 Gull, shot in Boston, April 1, 1«81, answering to the above description, has come into my po.sse.ssion , and I should unhesi- 

 tatingly pronounce it, as remarked by Mr. Howard Saunders in bis incomparable Work im the LarirKB, "An immature L. 

 g/aucus in the stage where the mottled brown of the immature stage has passed away and the pearly gray mantle has not 

 liei'un 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 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 jilumage quite unique a- 

 mong members of this Family, where none are described as ])a«;sing from a pale winter dress toadarker one in summer, and 

 if it does n it re-open the question ot the validity of Hutchinsi, certainly shows a new phase of jilumage for ijtaucus. 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 

 ono hundred uvules and could detect no ruptured capsules 



Puffinus fuliginosus. Sooty Shearwater. Size of Greater, but sooty-brown throughout, lighter beneath. 

 AltJioush corusidered bj nearly all writers, as a species, it may prove to be the young of the Greater Shearwater.
