In this subspecies the bill is shaped much like that of the New 

 Zealand and Kerguelen races, but it is larger and heavier, and the 

 culmen is less acutely ridged at its base. The following descrip- 

 tion based upon breeding specimens of antardka contains, of course, 

 manv characteristics common to its congeners :— Bill black, man- 

 dibular sulcus pearl blue; legs and feet pale flesh color with a 

 vinaceous and buff wash over the scales; iris olive brown; skin of 

 mentum blue under the feathers. Head dusky grayish-brown, 

 nearly black on lores; a white ring, broken in front and on the 

 anterior half of the lower lid, encircling eye; back and under surface 

 ashy gray, blending with the dark shade of head, and lightest in 

 center of back; rump and scapularies dark gray; wings dark brown- 

 ish-gray, changing to grayish-black on primaries; tail grayish- 

 black; shafts of quills white or whitish. 



A nestling 336 mm. in length is covered with long light gray down 

 except on the head, where a cap of short, dark gray dovoi is sepa- 

 rated from the nearly bare throat by a mask-like area of hairy, 

 light gray down. 



The nineteen specimens of this race, which we have had the pleas- 

 ure of examining, were, with one exception, taken at South Georgia 

 by Mr. Murphy or Mr. J. G. Correia.
