120 MR. J. E. HARTING ON ARCTIC BIRDS. [Feb. 7, 



Case 24. Common Guillemot. 



Vria troile, Linn. Syst. Nat. p. 220. 



In summer plumage. No locality noted. Common on the northern 

 coasts of Europe and America. A specimen in the Museum of the 

 Smithsonian Institution was obtained by the expedition under Capt. 

 Rodgers, on Herald Island, inside Behring's Straits. 



Case 25. Brunnich's Guillemot. 



Vria brilnnichii, Sabine, Trans. Linn. Soc. xii. p. 539. 



A good specimen in summer plumage, with the eggs. Brought 

 home in 1851 by Mr. Abernethy, ice-master to H.M.S. 'Felix.' 



Although similar in colour to Vria troile, this species is recogni- 

 zable by its much shorter and stouter bill. It is found on the northern 

 coasts of Europe, Asia, and America, and on the last named it is 

 said to be the commoner species (cf. Baird, B. N. Amer. p. 915). 



Cases 26 & 27. Black Guillemot. 



Vria grylle, Linn. Syst. Nat. p. 220; Latham, Ind. Orn. ii. 

 p. 797. 



Two in summer plumage (26), and one in winter (27). The 

 locality not noted. 



Case 28. Razorbill. 



Alca torda, Linn. Syst. Nat. p. 210. 



For this specimen, which is in summer plumage, no locality has 

 been noted. The species is very abundant on the N.E. coast of N. 

 America, aud appears to be in every way identical with the Old- 

 World species. 



Case 29. Little Auk. 



Alca alle, Linn. Faun. Suec. p. 50. 



Male, female, and young ; the two last (taken from the nest in 

 Wolstenholm Sound, lat. 76|° N., long. 68° W.) were brought home 

 in 1851 by Mr. Abernethy, ice-master to H.M.S. 'Felix.' 



Case 30. Northern Puffin. 



Mormon glacialis, Leach (nee Audubon, nee Gould) ; Baird, Birds 

 N. Amer. p. 903. 



Killed in Behring's Straits, and brought home by Capt. Moore, 

 H.M.S. 'Plover,' 1849-50. 



Professor Baird thinks this may be the young of M. comiculata, 

 Naumaun, " only differing from it in having the throat white, or 

 light ashy " (instead of black), " and a short obtuse horn over the 

 e y e " ( c f- Birds N. Amer. p. 903). It is possible, however, that 

 the specimens which suggested this opinion were immature, or 

 obtained in winter. Professor Newton, who procured several speci- 

 mens of M. glacialis in Spitzbergen, and who considers it distinct
