534 Mr. H. J. Pearson on the Birds observed 



65. Larus fuscus. 



Several Lesser Black-backed Gulls were constantly about 

 the ship in Peisenfjord during the early part of our stay. 

 We first saw them on Heno, June 26th ; a large colony had 

 then arrived, and were nesting near the shore down the east 

 side of the island. 



66. RiSSA TRIDACTYLA. 



An immense colony of Kittiwakes were breeding on the 

 cliffs of Sharanov Point, at the south-east corner of Ribatschi 

 peninsula, June 20th. Many of the eggs were much in- 

 cubated, but we saw no young. 



67. Stercorarius crepidatus. 



Eichardson^s Skuas were very common on Heno, the light 

 and dark forms being nearly equal in number. We took 

 the first egg on June 13tli, and continued to see other eggs 

 till July 13th, the latter probably belonging to birds we had 

 disturbed before. One nest contained three eggs, all nearly 

 fresh. These birds were also nesting on various points of 

 the Ribatschi peninsula and near Litsafjord. 



68. Stercorariits parasiticus. 



Buffon's Skuas were nesting at two places on Ribatschi 

 peninsula (June 20th) within an hour's walk of the sea and 

 at no great elevation ; the higher land was then all covered 

 with snow. On July 9th three pairs had eggs, much incu- 

 bated, at an elevation of 700 feet (considerably above the 

 line of bush-growth), some miles beyond Petschenga lake. 

 This species generally selects a breeding-place on high 

 ground further from the sea than the preceding one. 



69. Alga torda. 



We frequently saw Razorbills with the Puffins on Heno, 

 and presumed they were also breeding in holes, as no suitable 

 rocks or cliffs existed there. 



70. Uria grylle. 



Black Gruillemots were very common round Heno, and 

 generally distributed along all the coasts visited.
