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. 

 jNIany of them were gorged with food, and unable to rise 

 Ironi the water as the ship approached them. 



With the Guillemots were the comical-looking Black 

 Puffins, Lunda cirrhata (Pall.), in great al)undance, a bird 

 totally imrcpresented 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 

 shi[), and either tried to escape by diving or flapped with 

 might and main along the top of the water. Their bright 

 red legs, carried Avith 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 (Edemia 

 deghvndi Bp., or ffi. carho (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, 

 Phalacrocoracn pelagicvs 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, Lams schistisagus Stejn. Inside 

 Avacha Bay this species was numerous, but I brought home 

 only one sj)ecimen, a female, shot in Tareinski Harbour, 

 which weighed 4 lbs. The sharp boundary between the range 

 of this and Larus glauccscens Xaum. is curious, the former
