Adult male. Similar to Tlialassogeron culminata so far as the colour 

 of its plumage is concerned. The bill is paler, the culminicorn at 

 the base wider, almost touching the upper edge of the latericorn, 

 and with a well-defined posterior margin ; whole of the culminicorn 

 yeUow ; under wing-coverts pure white ; legs and feet red. Total 

 length about 34 inches, wing 20-8, tail 7-7, bill from gape 5-1, 

 from base of culmen 4-7, tarsus 3-3, middle toe 4-7, outer toe 4-55, 

 inner toe 4. 



Hah. New Zealand Seas. 



This species is somewhat intermediate between Diomedea and 

 Thalassogeron, as the culminicorn does not expand at the base so 

 much as in more typical Diomedea, but there is no intervening skin, 

 between it and the latericorn, as in Thalassogeron.
