Adult (Teneriffe, May). Upper parts slaty brown, darker on the crown and lower back, and paler and

The adult female does not differ from the male, and the adult plumage is assumed directly after the down 

 stage, the immature feathered birds not differing from the adult in plumage. 



According to Mr. Ogilvie Grant the males are, on the average, distinctly smaller than the females, the 

 average length of the wing in the male being 6'25 inches, and that of the female 6 - 38. 



The present species inhabits the seas of the southern hemisphere, ranging north to the Canary
