IIab. Antarctic Ocean ; accidental in Western New York (Livinj,'stou Co., Jidc Prkwster, 1. c.) ( 

 Si>. CiiAii. Adult ? (type specimen, No. ir)70(), Antarctic Ocean ; T. R. Peai.e): Above, nearly 

 unil'orni brownish slate, more plumbeous on the secondaries and greater win^'-coverts, which have 

 very narrow (barely visible) whitish niar!,'iiis ; paler, and with the basal white shining through on 

 the occii>ut and nape. Lores, cheeks, chin, and throat white, the two latter immaculate ; frontal 

 feather slightly margined with whitish, and superciliary region mixed with white (only the tips 

 (if the feathers being dusky), forming a broken superciliary striiie extending nearly to the occi])iit ; 

 ante- and sub-cu'bital regions nearly uniform dusky, but feathers with white ba.ses. Lower parts 

 white, but this overlaid on breast, abdomen, Hanks, and anal region with smoky pliunbcous, appear- 

 ing almost uniformly of this color where the feathers are undisturbed ; jugulum transversely mot- 

 tled or vermiculated with dusky ; crissum immaculate white. Lining of wing pure white, except 

 anteriorly and exteriorly, where the color is uniformly dusky ; inner wel)s of primai ies pure white, 

 with an abruptly defined grayish stripe next the shaft. Tail uniform brownish gray, the inner 

 web of the exterior feather white, mottled, or irregularly .speckled, with gray. Bill uniform black : 

 tarsi and base of toes, with wiibs, pale colored (pinkish or flesh-colored in life), the terminal 

 piiition of the feet blacki.sh. 



Wing, 10.00 inches ; ttiil, 4.(X) ; culnien, 1.0.5 ; nasal tubes, .30 ; length of mandible, measured 

 from malar apex, .85 ; gonys, .25 ; tarsus, 1.30 ; mi(hlle too, without claw, 1.25. 



Alth(jugh Mr. Cas.sin (1. c.) says that the specimen described above, and which is unquestion- 

 ably llie typ(; of Proccllaria gularis, Peale, " is (piite identical with the type of P. mollis, of which 

 there are numerous specimens, including those of Mr. Gould, in the museum of the Philadelpliia 

 Academj'," he evidently overlooked the radical dilference in the coloration of the under surface 

 of llie wing. Dr. Coues, who examined the Pliiladel[)hia Academy .series, says (1. c.) that in all of 

 these "the under surface of the wing is chiefly dusky brownish ; but there is an illy-defined and 

 interrupted area of whitish, particularly toward the base of the primaries," (li. ijulnris, then, must 

 he considered as more nearly related to (.E. FIshcri, (E. Dc.filijipinna, (E. tjavia, and (Ji. desolnta, all 

 of which have the under surface of the wing mainly or largely white. 



A Petrel described by Mr. Brewster, ill the "Bulletin of the Nuttall Ornithological Club" for 

 April, 1881, from a specimen obtained in Livingston Co., N. Y., in April, 1880, i.s supposed to 

 belong to this species. Mr. P)rewster's description is as follows : — 



" Adult (/) fhuiuKje, (Xo. 5224, author's collection, Mount Morris, Livingston Co., N. Y., 

 .\pril, 1880) : Upper parts, including tail-coverts and exposed surfaces of ivctrices, pure cinereous, 

 wiiicli deepens to plumbeous only on the occiput, rump, and wings, the latter having the middle 

 iiiiil greater coverts of the same tint as the back. The feathers of the back (but not those of the 

 riiiii|) or occiput), with the greater and middle wing-coverts, broadly tipped with ashy white, 

 1,'iving these parts a .scaled appearance. Tin; throat, juguliun, upper part of breast, and under tail- 

 coverts, pure silky white. The cinereous of the upper parts conu!s down along the sides of the 

 neck, encroaching more and moiv, and deepening in tint as it extends backward, until it throws 

 aiio.ss the abdomen a broad band of nearly pure idumhec" ■.. Around this coloivd tract there is 

 nowhere a definite line of demarcation ; the cinereous of the neck fa(h!s imperceptibly into the 

 white of the throat, and the edges of the alxhnniual bar become mingled with white, until the dark
