lid ; rump, upper tail-coverts, and all the under surface pure- 

 white ; bill black, with the exception of the cuhnen and tip 

 and the lower edge of the basal three-fourths of the under 

 mandible, which are horn-colour. 



In the youthful state the head and neck are dark grey, and 

 the bill is of an almost uniform brownish black, with only an 

 indication of the lighter colour of the culmen.

This species came under my observation for the first time 

 on the 24th of July, 1838, in Lat. 30° 38' S. and Long. 

 20° 43' W. ; from which period until we reached New South 

 Wales scarcely a day passed without the ship being visited by 

 it ; upon some occasions it appeared in considerable numbers, 

 of which many were apparently birds of one year old, or at 

 most two years of age ; these may be easily distinguished 

 from the adults, especially while flying, by the darker colour- 

 ing of their wings, back, and tail, and by the culmen of the 

 bill being less distinctly marked with yellow. 



The Yellow-nosed Albatros is plentiful off* the Cape of Good 

 Hope, and iu all the intermediate seas between that point and 

 Tasmania ; I also observed it off Capes Howe and Northum- 

 berland on the southern coast of Australia, and Gilbert states
