observed on the Yenisei River. 107 



their greater size and quite black backs and wings, compared 

 with the grey of L. affinis, were easily distinguishable when 

 the two were flying round the stern of the vessel together. 



-^115. Larus GLAUCus. Glaucous Gull. 



First seen on our trip in the s.s. ' Oftsin/ a nest and 

 young in down being found on a small sandbank near 

 Sibiriakoff Island; the young birds were taken on board 

 ship by the sailors and soon became very tame. The 

 commonest Gull in the Kara Sea. 



■ 116. Stercorarius POMATORHiNus, Pomatorhiue Skua. 



It was only on one of the many islands visited that we were 

 lucky enough to come across many of these birds nesting. 

 Several pairs were scattered over a large marsh, which 

 would have been quite impassable if it had not been for the 

 ice a couple of feet below ; but the possibility of discovering 

 these rare eggs encouraged us to toil on, with the reward 

 of finding two nests. A third nest was afterwards found 

 by Hill on the mainland, and a good many birds were seen 

 at Golchika later in the season. Our eggs measure from 

 2-35 in. to 2-65 in. by 1-79 in. to 1-86 in. 



-f 117. Stercorarius crepidatus. Richardson's Skua. 



A few were seen at Golchika, and one nest found belong- 

 ing to a bird of the light form, which was the only form 

 observed. 



118. Stercorarius parasiticus. Buffon's Skua. 



This Skua must have increased since Seebohm's visit in 

 1877, as he only once mentions having seen any, whereas 

 we found them plentiful at almost every place that we 

 stopped at above the forest, and often found a nest, at which 

 the birds were very bold, sometimes striking us with their 

 wings, and when once the nest was found the parent bird 

 would return to it if we withdrew only a few yards. 



119. FuLMARus GLACiALis. Fulmar. 



On our return voyage through the Kara Sea, a Fulmar 

 appeared in lat. 74° 8' N. and long. 77° 40' E.
