regia Buller, and dilating on the shape of the bill as a diag- 
nostic character." The extensive series now under review 
show that the individuals of Tubinarine species are subject to 
much variation in the form and size of the bill. 
A later candidate for recognition is Diomedea sanfordi 
Murphy,’ separated from D. exulans on the basis of variation 
in one specimen. Especial value is attached to the shape of 
the nasal tubes. This character, however, is a highly variable 
one in the Diomedee.

As indicated in the Key to the Species, the basal width of 
the latericorn and that of the upper mandible divide the 
rounded-tailed albatrosses into two distinct groups, and these 
I have recognized as genera.* By this arrangement, Thalas- 
sarche Reichenbach becomes available as the name of the sec- 
ond genus of the family, Thalassogeron Ridgway sinking into 
a synonym. 
I am of the opinion that Diomedea plate: Reichenow is the 
young of T. melanophris. In the albatrosses much remains to
