420 THE AMERICAN NATURALIST. 
Under the names of the various birds observed in the body 
of this memoir are given full accounts of habits, localities, 
plumage descriptions, and matters of general interest to orni- 
thologists everywhere. At the close of the work we find an 
index, which simply presents the scientific names of the thirty- 
three (33) species of birds observed during the entire journey. 
They are as follows: gialitis hiaticula, Alle alle, Anser sege- 
tum, Archibuteo lagopus, Arquatella maritima, Branta bernicla, 
Cepphus mandti, Colymbus arcticus, Crymophilus fulicarius, 
Falco esalon, Fratercula a. glacialis, Fulmaris glacialis, Ha- 
relda glacialis, Lagopus lagopus, Larus argentatus, L. fuscus, 
L. glaucus, L. marinus, Nyctea scandiaca, Pagophila eburnea, 
Phalaropus hyperboreus, Plectrophenax nivalis, Rhodostethia 
vosea, Rissa tridactyla, Somateria mollissima, Squatarola hel- 
vetica, Stercorarius crepidatus, S. longicaudus, S. pomatorhinus, 
Sterna macrura, Totanus nebularius, Uria lomvia, and Xema 
sabini. In other words, it will be noted that there was but one 
passerine bird observed (the snowflake, P. nivalis) ; a ptarmigan, 
five waders, two hawks and an owl, two ducks and two species 
of geese; and the balance of the list, made up of gulls, terns, 
guillemots, auks, fulmars, jægers, and the dovekie, together with 
divers and puffins, represent strictly a circumpolar avifauna — 
few birds, and those essentially boreal forms. Taken as a whole, 
this is one of the most important contributions to the orni- 
thology of high northern latitudes now extant, and it constitutes 
a very substantial addition to our knowledge of the habits, 
species and migrations, plumages and variations of the ornis of 
the Arctic Circle, and its distinguished authors are to be con- 
gratulated upon the completion of their worthy labors.
