PROCELLARIID.E — FULMARIN.E: FULMARS, ETC. 1029 



tioii of Dutch mallemugge.) Length 18.00-20.00; wing 12.50-13.50; tail 4.50-5.00; chord 

 of cuhnon 1.50 (1.30-1.80); hill ahoiit 0.75 deep at base, and nearly as wide; nasal tube 0.60 

 long ; tarsus 2.00 (average) ; middle toe without claw 2-25. Adult $ 9 , normal plumage : 

 White; mantle pale pearly-blue, restricted to back and wings, or extending on head and tail; 

 u.sually a dark spot in front of eye ; quills dark ashy-brown. Bill yellow, tinged with sea- 

 green on culmen and lower mandible, the opening of the nostrils black ; feet drying dingy yel- 

 lowish, said to be delicate french gray in life ; iris brown. Young : Smoky-gray, paler below ; 

 feathers of upper parts with darker margins; primaries as in the adult; bill and feet obscured. 

 Some individuals appear to be permanently dark-colored, like this, and it is certain that Ful- 

 mars breed in such state. They are therefore " adult " ; but it may easily be that a change 

 requiring several years for its completion goes on, tending to the final white and pearly-blue 

 plumage of sufficiently old birds. The Fulmar is extraordinarily abundant in the N. Atlantic, 

 swarming at some of its favorite breeding places, especially St. Kilda, where some 20,000 young 

 have been taken in one month of August, wide ranging at other seasons; in North America S. 

 casually to New Jersey in winter. Nest on crags over the sea; e^g single, white, with rough 

 brittle shell, resembling a hen's egg in size and shape, about 2.85 X 2.00; young covered with 

 whitish down, fed in the nest by regurgitation of an oily fluid. Fulmars are very greedy of 

 fatty substances, and constantly attend the whale-fishery to feed upon blubber. 

 F. g. minor. Lessp;r Atlantic Fulmar. Like the last: Smaller; wing 12.00 or less; 

 bill l.;i5, its depth at base 0.()5; tarsus 1.75; middle toe 2.15, but the difi"erence is slight, and 

 the alleged distinction arbitrary : see CouES, Proc. Phila. Acad. 1866, p. 27. N. Atlantic, 

 with the last ; in North America S. in winter to Massachusetts. Proc. minor Kj^erbolling,

Obs. — F. g. columba Anthony, Auk, 1895, p. 105, is described as differing from gbipischa in smaller size, as minor 

 does from glacinlis. San Diego, Cal., in winter. 



h\ g. glupis'cha. (Latinized from the Russian name.) Pacific Fulmar. GtLUPISCH. 

 Averaging darker than glacialis; mantle bluish-cinereous rather than pearly-blue in the light 

 phase ; in the frequent dark phase the whole plumage sooty -gray, little lighter below than 

 above; bill rather weak, usually light-colored. Size of ^Zaem?is or rather less ; length 17.00- 

 I'J.OO; wing about 12.00; bill 1..5(), its deptli at base 0.67. N. Pacific, in vast numbers; 

 on our side S. in winter to Mexico. Habits, nest and egg, the same as those of the Common 

 Fulmar. Proc. glacialis Pall. 1811. Proc. pacifica Aud. 1839, nee Gm. 1788. Fulmartis 

 f/lacialis pacificus Bp. 1855, and of former eds. of the Key. F. g. glupischa Stej. Auk, 1884,

F. g. rod'gersi. (To Com. John Ilodgers, U. S. N.) RonOERS' FuLMAR. Mantle dark, 

 as in glupischa, but much restricted, most of the wing-coverts and inner quills being wliite ; 

 primaries mostly white on inner webs, their shafts yellow. No sotity jdumage recognized. 

 Size and shape as before. N. Pacific, swarming to breed ou some of the rocky islands in Ber- 

 ing Sea ; S. in winter to San Diego, Cal. Nest on crags ; single egg white, nearly equal-ended, 

 rough, with innumerable pits and points, 2.90 X 1-90; chick hatches like a puff-ball of white
