Sp. Ca.—Tail of 14 feathers. Prevailing color white; the under surface and sides of body, hinder part of back, rump, and 
tail, black. Wings white on both surfaces, except the quills, which are black. Narrow margin inferiorly of the frontal process 
of bill and the forehead violet black, this color bifureating opposite the middle of the eye, and continued broadly on each side 
the head to the nape, the color extending a little below the eye; the white below and behind the black glossed with transparent 
emerald green; the interspace white. Length, 26; wing, 11.24; tarsus, 1.82; commissure, 2.53. 
Hab.—Atlantie and Arctic coasts of northern hemisphere; Pacific coast N. A.? 
There is a faint tinge of purplish cream color in the white, especially conspicuous on the 
breast and wings. The black of the back and belly is separated by white on the flanks. 
The tertials have a slight outward bend, but much less than in S. spectabilis. The frontal 
process of the bill is elongated and rounded behind, and about in a line with the culmen.
