Birds observed in Kamchatka.

eyelids pink ; of legs and feet light flesh; of claws horn 
with the tips lighter. 
Dr. Stejneger describes the colour of the feet as "pinkish 
flesh-colour,” and remarks that this character at once dis¬ 
tinguishes L. schistisagus from L. affinis, which is said to have 
the feet yellow, and also from L. marinus, in which the flesh- 
colour is very pale and rather greyish. Very little seems to be 
known about the distribution of this species, nor did my trip 
to Ukinsk Bay add to our knowledge on that point, for I 
have no notes of having met with any large Gulls in that 
neighbourhood. It was described from Avacha Bay, in 
Southern Kamchatka, and only occurs as an occasional 
straggler on the neighbouring Commander Islands, where it 
is represented by the totally different L. glaucescens Naum. 
For the intermediate localities we had no certain record 
until Dr. Stejneger found it to be, next to the Kittiwake, the 
commonest breeding Gull of the Kurils*. It is therefore of 
interest to record that I saw numerous Black-backed Gulls, 
many in a light immature plumage, on Robben Island, Sak¬ 
halin, when I visited it on July 11, 1896, and that, although 
I did not obtain a specimen there, I distinctly noted that 
the colour of the legs of these Gulls was pink, so that in all 
probability they were L. schistisagus , since the colour of 
the legs of this species should be far more conspicuous and 
noticeable than are those of L. marinus . In Ukinsk Bay no 
adult large Galls were seen. A young bird of the year, of 
the size and general appearance of the young of L. glaucescens , 
was observed near Karaga, but could not be identified on the 
wing.
