seen in flocks composed of that sex only, were much fewer in 

 numbers, and extremely wary, so much so that I believe three 

 specimens made up our total bag ! 



15. Mandt's Guillemot {Cepphus mandti, Newton, ' Ibis,' 

 1865, p. 517). — Very plentiful. Chapman observed a single Black 

 Guillemot, early on the morning of July 24th, a short distance 

 south of Bear Island ; this would in all probability be referable 

 to Cepphus grylle. No others were observed until we were some 

 way up the Spitzbergen coast, but on entering Is Fjord they 

 became common ; and from that time some were nearly always 

 in sight, floating tamely round the ship, resting on pieces of ice, 

 or, less commonly on the wing. There were quantities at the 

 edge of the ice off Vogelsang. Chapman observed a few breeding 

 at Botges Hill, Magdalena Bay. On our second visit to Is 

 Fjord, August 3rd, amid the general decrease in bird-life, a few 

 of this species were still to be seen in pairs. We saw some of 

 them the following day on our way south, and the last of them 

 (or they may have been C. grylle) among the ice to the north of 

 Bear Island that evening. Professor Newton, in his paper in 

 ' The Ibis ' on the " Birds of Spitzbergen," to which I have so 

 frequently referred, particularises the differences between this 

 species and C. grylle, so I will here merely add a sketch of the 

 bills of the two species. 



C. grylle, male. 



C. mandti, male. 



16. Brunnich's Guillemot (Uria bruennichi, Sabine). — If I 

 had not read in Professor Newton's paper that he considers the 

 Little Auk the most abundant species in the Spitzbergen Ornis, 

 I should have unhesitatingly pronounced the present species to be 

 so, which is also Chapman's opinion (of course only as far as 

 regards the west coast, which side alone we visited) ; and we have 

 the high authority of Dr. Malmgren on our side, though it is just
