 YELLOW-NOSED ALBATROSS. 



DiOMEDEA CHLORORHYNCHOS, GmEL. 



A SKIN of this bird was sent to me by Dr Townsend, who pro- 

 cured it in the Pacific Ocean, not far from the mouth of the Columbia 

 River. The species is well known, and one which, unlike most of the 

 others, has been tolerably well described.

Bill longer than the head, nearly straight, stout, much compressed. 

 Upper mandible with its dorsal outline much declinate and nearly 

 straight for a third of its length, then concave, ascending to the unguis, 

 on which it is arched and decurved in the third of a circle, the ridge 

 broad, convex, rounded at the base, separated in its whole length by a 

 groove, margined below beyond the nostrils by a prominent line, from 

 the sides, which are erect and convex, the edges sharp, the unguis de- 

 curved, much compressed, with its sides flattened, and the tip acute. 

 Nostrils sub-basal, prominent, tubular, having a horny sheath. Lower 

 mandible with the angle very narrow, reaching to the tip, and having 

 at its extremity a long slender interposed horny process ; the outline of 

 the crura gently ascending and quite straight until near the end, when 

 it is a little decurved, the sides ascending, nearly erect, a little convex, 

 the edges sharp, the tip extremely compressed, its upper edges decur- 

 ved. 



Head rather large, ovate, compressed anteriorly ; neck of moderate 

 length ; body full. Feet rather short, stoutish; tibia bare for three-quarters 

 of an inch, covered all round with small angular scales ; tarsus roundish, 

 reticulated with small angular and roundish scales ; toes three, long, 

 slender, the outer very little shorter than the middle, which exceeds 

 the inner by three-quarters of an inch ; they are covered above with 

 small angular scales for half their length, in the rest of their extent 

 with scutella, and connected by emarginate webs, the outer and inner 

 with an external lobed membrane. Claws rather small, slender, slightly 

 arched, rather depressed, convex above, somewhat obtuse.
