SaLvin—Cstrelata leucoptera, 399, 416.

I am unable to determine the status of 4strelata longiros- 
tris Stejneger and Procellaria leucoptera Gould without com- 
paring the type of the former with a series of the latter 
from its type locality, Port Stephens, New South Wales, Aus- 
tralia. 
The specimens of P. P. axillaris, hypoleuca, longirostris 
(provisionally determined), brevipes, nigripennis, and cooki at 
my disposition show no intergradation.

In No. 151108 U. S. Nat. Mus. light gray vermiculations 
extend across the jugulum, forming a faint band about half 
an inch in width. Another specimen has a similar but nar- 
rower band, and another still, indications of one.
