Adult. Unknown. 
Immature. Agrees in general coloration with the adult of Th. cMororhynchos hassi, but 
differs from that in the colour of the biU, which is in this wholly black (due to 
immaturity) ; “ Irides black ; feet and legs yellowish-white ” (Carter) ; culmen 
(exp.) 114 mm. long, depth at base 36 ; wing 462 ; tail 165 ; tarsus 75. 
Nestling, Eggs, and Nesting-place. Unknown. 
The, at present, unique specimen representing the subspecies was obtained 
by my friend Mr. Tom Carter, who wrote : “ On 11th May, 1900, one of the 
native boys went to the boat to wash her decks down as usual, and returned 
with a beautiful live albatross, which he had caught from the dingy. It was 
in fine plumage, and apparently uninjured, except at the point of the wing, 
but was in a very emaciated condition. I could not quite make it tally with the 
description of T. cTilororJiynchus, but marked the skin so, as it seemed to be 
nearest that species.” This skin afterwards passed into the possession \ of the 
Tring Museum, when it was named by Rothschild after Mr. Carter, thus : — 
“ Thalassogeron carteri ^ n. sp. 
“Differs from Thalassogeron chlororhynchus in having the bill, including 
the culmen, black, the face and sides of the head white, without the grey tinge
