118 ALBATROSS EXPLORATIONS, BIRDS RIDGWAY. 



lower neck, all round, pale gray,* below extending over the sides of the 

 breast, and fading gradually into the pure white of the middle of the 

 breast and other nuder parts, but above gradually deepening into the 

 uniform medium grayt which covers the back, scapulars, wing-coverts 

 (except the lower greater and those along the margin of the wing), 

 tertials, and rump; upper tail-coverts and tail entirely pure white, 

 this abruptly contrasted with the deep gray of the rump. Exterior 

 scapulars broadly and abruptly margined with pure white, forming 

 a continuous and conspicuous narrow stripe along each side of the 

 dorsal region ; marginal wing-coverts, alulae, lower greater coverts 

 and upper secondaries, pure white; lower secondaries with outer webs 

 very pale gray; four innermost primaries very pale gray, narrowly 

 margined with white ; sixth similar, but with a blackish blotch near the 

 tip, extending quite across the inner web and for some distance along 

 its edge; fifth quill mostly pale gray, with dusky shaft, the terminal 

 portion (for about 1.30 inches along the shaft, black, this color much 

 more extensive, however, along both edges), but with a small white 

 apical spot; fourth quill with black much more extensive (ext ending 

 nearly 5 inches from tip on outer web or 1.75 to nearest point on the 

 inner), with still smaller white apical spot, the rest of the inner web 

 white, becoming gray next to the shaft; third quill with black extend- 

 ing about 6.80 from the tip, or almost to the coverts on outer web, and 

 2.00 to nearest point on the inner, the white portion separated from the 

 shaft by a dusky stripe ; second quill similar but with the whole exposed 

 portion of outer web black, but the black on inner web a little more re- 

 stricted ; first quill similar, but black near tip of inner web more 

 restricted, though the stripe along the shaft is broader. (The three 

 outermost quills have the white apical spots reduced to minute specks, 

 which would entirely disappear with a very slight wearing of the 

 feathers.) Bill, black, with a little less than the terminal third (or for 

 about .70 of an inch from the tip) yellowish horn-white or pale olive- 

 buff; rictus and broad, tumid eyelids, orange-red; iris, carmine; legs 

 and feet, deep red; claws, deep black. Length (mounted specimeu) ? 

 about 20.00 ; wing, 16.25; tail, 7.40 (forked for 2.50); exposed culmen, 

 1.90; depth of bill at angle, .50; at base of culmen, .68; tarsus, 2.00; 

 middle toe, 1.80. 



Adult female in breeding plumage (No. 115968, same locality, etc.) : 

 Similar to the male, but with the slate-colored "hood" even less dis- 

 tinctly defined (approaching abrupt definition only on the fore neck), aud 

 white patch at base of upper mandible more restricted (averaging not 

 more than .25 wide), the white spot on the malar apex also smaller (al- 

 most obsolete on one side). Length (mounted specimen), about 18.00; 

 wing, 15.75; tail, 7.60; (forked for 2.60) ; exposed culmen, 1.90; depth 

 of bill at angle, .47; at base of culmen, .65; tarsus, 1.98; middle toe, 1.70.
