The bird from the west coast of South America whose breeding-place is at 
present unknown, is easily separable by the entire absence of grey on the lores 
and by the black about the eye being reduced to a very faint marking. Its 
bill is as long as that of the Kerguelen bird, and is also deeper. For this race 
I introduce the name 
Thalassarche 7nelanophris ricTi^nondiy subsp. n. 
272
