While the nations of the Western World were killing each other off by mill- 
ions on Flanders fields, in the Great War, Scandinavian moss students were 
busily engaged in the study of the moss flora of Arctic Asia. There has come to 
hand, as evidence of industry, a notable report by Prof. H. Wilh. Arnell, dated 
191 7; in German. 
Die Moose der Vega-Expedition. Von H. Wilh. Arnell, Arkiv for 
Botanik, Band 15, No. 5. Stockholm, 191 7. 
This is a report of the mosses collected in 1878 to 1880, on the occasion of 
the first circumnavigation of the Eurasian continent under the direction of Pro- 
fessor A. E. Nordenskiold. This Swedish expedition is named after the Steamship 
Vega which carried the expedition. 
This is a volume of iii pages. In the first 20 pages the author discusses 
the physiographic and climatic conditions of the regions between Novaja-Zemlja 
Island and the territories surrounding Bering Sea.^ He also reviews previous 
collections and discusses the principal moss associations. In Tabelle I he enum- 
erates 85 most characteristic species and notes their relative frequency on Novaja 
Zemlja, in northern Siberia, and in the Bering Sea regions. 
The systematic list, which treats the geographic distribution in detail, com- 
prises 65 species of Hepaticae, 16 Sphagna (determined by C. Jensen), and 188 
species and varieties of Musci. 
The most notable critical systematic notes are on two varieties of Cephal- 
ozia btcusptdata, vars. cavifolia and atrata; on Haplozta polaris;. on Jungermanma 
alpesttis, porphyroleuca, and mmmanica; on Qligotrichum cavifolium {Psil- 
opilum tschuctichuum) ; on Bryum aispulum; on Bryum inclinatum; on Swart- 
zia Hagemi {Dtstichtum Hagenii), on Ceratodon purpureus and varieties; on 
Amblystegium aduncum and latifohum, to the latter of which species over six 
pages of critical notes are devoted. 
The species and varieties described as new are- Cephaloziella Hampeana 
stbirica C. Jensen; Bryum Lundstroemii Arnell; Bryum synoicum AineW; Bryum 
inclinatum macrosporum Arnell; Bryum inclinatum alaskanum Arnell; Bryum 
inclinatum heringianum Arnell; Bryum Kjellmanii Arnell; Bryum subacutum 
Arnell; Bryum purpurascens aculeatum Arnell; Bryum longirostratum Arnell; 
Dicranum elongaium longifohum C. Jensen; Ceratodon purpureus rotundifolius 
Berggr.; Grimmia grjicilis hyperborea Arnell.

1 Note: It was Captain Bering, not Behring, that gave name to Bering Sea. All Amer- 
ican geographies now spell the name Bering.
