wrongly reduced to a subgenus of Fulmarus by the A. 0. U. 1886-95. Mr. Salvin, indeed, 

 places it in a different subfamily. It is closely related to the exotic genus Thalassceca, with 

 which I once combined it (Proc. Phila. Acad. 1866, p. 29) but the rectrices are 14, as in Ful- 

 marus (not 12). The A. 0. U. reverted to the Key in 9th Suppl. List, Auk, Jan. 1899, 

 p. 100, after CoUES, Auk, July, 1897, p. 31.5. 



P. glacialoi'des. (Lat. glacialis, icy, and Gr. el8os, eidos, resemblance ; i. e. like the Fulmar, 

 F. glacialis. Fig. 705.) Slender-billed Fulmar. Adult $ 9 : Plumage white, with clear 

 pearly-blue mantle and black primaries, just like a Gull. Mantle beginning faintly on nape, 

 continuing over whole back, rump, tail, wing-coverts, and inner quills ; edge of wing slaty-gray ; 

 lining of wing mostly white; primaries black, their shafts yellowish -white at base, their inner 

 webs pearly-white to near the ends ; white of first primary extending to within 2.00 of the tip, 

 farther on the rest successively, reaching end of 6th ; outer webs of secondaries slaty-black, 

 inner white ; a small dusky spot before eye ; a faint pearly shade on sides of breast and body. 

 Bill yellow ; nasal tube, hook, and sometimes base of upper mandible obscured with bluish horn- 

 color or blackish ; feet pale flesh-color, obscured on outer toe, drying yellowish. Length about 



Fig. 705. — Slender-billed Fulmar, nat. size. (From Elliot.) 



18.50; extent about 36.00; wing 13.00; tail 5.25, the feathers graduated about 1.00; tarsus 

 2.00; middle toe and claw 2.60; outer ditto 2.70; inner ditto 2.25; chord of culmeu 2.00; 

 height or width of bill at base 0.75; nasal tube 0.67; the bill is really very stout, only " slen- 

 der" in comparison with that of the Common Fulmar. Young not seen; stages of plumage 

 probably coincident with those of Fulmarus. A species described under a large and not select 

 assortment of names, both generic and specific, but easy to identify ; wide-ranging over much 

 of the water of the world ; occurs on the Pacific coast of North America N. to Vancouver 

 Island ; but the Kotzebue Sound record is erroneous (mistake for Puffimis tenuirostris, the 

 Slender-billed Shearwater: see Auk, 1884, p. 233). Proc. tenuirostris Aud. 1839, nee Temm.
