Mr. G. E. H. Barrett-Hamilton on 
Guillemots, Uria lomvia arra (Pall.), were everywhere to 
be seen, both in the open sea and in Avacha Bay, where 
they follow the fish into the inner recesses of the harbour. 
Many of them were gorged with food, and unable to rise 
from the water as the ship approached them. 
With the Guillemots were the comical-looking Black 
Puffins, Lunda cirrhata (Pall.), in great abundance, a bird 
totally unrepresented by any corresponding species in the 
Atlantic. Like the Guillemots, they were so gorged with 
food as to be unable to rise from the sea at our approach. 
Yet they were in very great terror at the appearance of the 
ship, and either tried to escape by diving or flapped with 
might and main along the top of the water. Their bright 
red legs, carried with the feet close together behind them, 
gave them almost the appearance of having a red rump. 
Like the Guillemots, these birds, in their pursuit of fish, 
follow up the ramifications of Avacha Bay to quite a distance 
from the open sea. 
Once I thought I saw some Black Ducks, perhaps CEdemia 
deglandi Bp., or (E . carbo (Pallas), but I did not get a good 
enough view of them to make my observation certain, and 
I may well have been mistaken. 
The next species which we fell in with was a Black Shag, 
Phalacrocorax pelagicus Pall., with black, forward-pointed 
crest and bare yellow face. Later a Cormorant, P. bicristatus 
Pall., flew by us, wearing the white egg-like spots of the 
breeding-season on its flanks. A few more Shags and 
Cormorants were observed later in the day, but they did not 
seem to be numerous about Avacha Bay, and I only saw a 
few, and did not obtain a specimen during my stay there. 
Strange to say, I once saw a single individual of each of 
these quite different species flying together as if mated. 
At about the same time as we saw the Cormorants we came 
on a dark-mantled Gull, Larus schistisagus Stejn. Inside 
Avacha Bay this species was numerous, but I brought home 
only one specimen, a female, shot in Tareinski Harbour, 
which weighed 4 lbs. The sharp boundary between the range 
of this and Larus glauccscens Naum, is curious, the former
