encasing posterior part of under inaudible — the latter single, the other 3 pieces in pairs, 

 making 7 in all which are moulted; when dry, all these elements vermilion or coral-red, and 

 end of bill yellowish. (Before acquiring these _^^ 



outgrowths the young bird is tetraculus of au- 

 thors ; the adult in winter, after shedding them, 

 is dubius.) Adult ,^ 9 > i^ summer : Bill as 

 said in form, etc., in life crimson, with bluish 

 tip. A beautiful crest of 12-20 slender blackish 

 plumes springing from forehead, curling over 

 forward in arc of a circle to fall gracefully upon 

 bill ; at full length the plumes are about 2.00 

 long, not filamentous, but with well-formed webs, 

 and bundled or impacted together, owing to 

 oblique divergence of webs from shaft (iis in Lo- 

 jphortyx). One slender series of white filaments 

 behind each eye, drooping downward and back- 

 ward. Plumage otherwise sooty — more brown- 

 ish-black above, more brownish-gray below, but 

 belly not whitish, and no white on scapulars. 

 Feet bluish, with dark webs. Bill coral or 

 orange, with horn-colored tip ; inside of mouth 

 flesh-color. Aside from transformation of bill, 

 the young only difier in lacking crest and white 

 :filaments, but both are early acquired ; a white 

 spot below eye. Summer and winter plumages 

 are alike. Iris white, or with blackish outer and bluish inner ring ; in the young, brown. 

 Length 8.50-9.00; wing 5.25-5.50; tail 1.55; tarsus 0.90-1.00; middle toe and claw 

 1.35; chord of culnien 0.45. North Pacific, both coasts and islands, on Asiatic side to 

 Japan, and in Alaska to Kadiak. Nesting in every respect like C. psittaculus ; single egg 

 similar, smaller, 2-10 X 1-40.
