Distribution. Lord Howe Island. 
Adult male. Entire plumage sooty-black, darkest on the upper tail-coverts; wings and tail 
black. A large sub-terminal band of white is noticeable on the under-surface and the 
upper tail-coverts w T hen the feathers are examined. Bill, feet and legs black, eyes dark 
brown. Total length 225 mm. : culmen 13, wing 160, tail 79, tarsus 35. Collected 
at Mr. P. Digmans, on Lord Howe Island, on the 3rd of March, 1914, and is the type of

Sexes. Alike. 
Nest and eggs. Probably similar to other forms in this genus. 
I can see no reason to suppose this bird to be a melanistic form of any other. 
Mr. Roy 7 Bell, who collected for me, sent me a great number of the Rings of 
this bird.
