Simorhynchtis camtschaticus (Lepech.), Schl. — Habitat : North 

 Pacific Coasts. Unalaschka (Pallas). Kamtschatl<a (Mus. Best. Nat. 

 Hist. Soc.) North-west coast of America (Mus. Smiths. Inst.) 



Bill much smaller, simpler and differently shaped from that of 

 S. cristatellus, though not distantly resembling the juvenile un- 

 developed condition of the latter. Width at nostril very slightly less 

 than depth at same point, about two-thirds of the length of culmen ; 

 bill regularly >■ -shaped in lateral outline; culmen very convex, 

 regularly arched from base to tip ; gonys nearly straight, rapidly 

 ascending; commissure slightly sinuate, a little curved upward at tip; 

 apices of both mandibles acute, fairly meeting each other on the level 

 of the commissure ; tomia of upper mandible slightly nicked near the 

 tip of the bill. Wings and tail of usual shape for this genus ; the 

 length of the latter contained about three and a half times in the 

 length of the former from the carpal angle to end of first primary. 

 Tarsus much shorter than middle toe and claw ; middle toe a little 

 shorter than outer toe; middle toe and claw just as long as outer 

 toe and claw ; inner toe and claw a little shorter than middle toe 

 without its claw. 



The form of the bill alone is characteristic ; the other details of 

 structure are shared by the rest of the Simorhynchi. 



A very long recurved crest of exceedingly slender, delicate, filoplu- 

 maceous feathers, six (to ten ?) in number, springing from the anterior 

 part of the forehead, about opposite the anterior edge of the orbits, 

 brownish black ; a single series of slender filamentous feathers from 

 each side of the base of the culmen, and thence to the superior border 

 of the orbit ; a second similar but shorter series from the edge of the 

 commissure, and thence along the lower part of the side of the jaw; a 

 third similar series from the posterior canthus of the eye, and thence 

 adown the side of the neck ; yellowish white. Body colours almost 

 uniform; brownish black, sometimes with more of a grayish, sometimes 

 with more of a fuliginous hue ; the wings and tail most intense in , 

 colour, frequently nearly black ; the under parts, particularly the belly, 

 lighter and more grayish brown, inclining to mouse-colour. Bill orange- 

 red, its apex salmon-colour, or more decidedly yellowish. Legs (in the
