DESCRIPTION OF THE SPECIES. 
Untess otherwise stated, the references to Professor G. O. Sars are to his ‘‘ Crustacea 
of Norway,” Vol. I., Amphipoda, 1895; those to Mr. Stebbing (Rey. T. R. R.) are to his 
‘Challenger’ Report; and to A. O. Walker, to the Amphipoda of the ‘ Southern Cross’ 
Antarctic Expedition, Journ. Linn. Soe., London, Zoology, Vol. XXIX. (1903), 
pp. 38-64. 
The classification of the species is, as far as possible, im accordance with that of 
Professor G. O. Sars, in the “ Amphipoda of Norway.” After the completion of this 
memoir (on October 30, 1906) I received, through the kindness of the author, the Rev. 
T. R. R. Stebbing, F.R.S., a copy of his invaluable work on the Amphipoda Gammaridea, 
written for “ Das Tierreich.” As this will be indispensable to all systematic workers on 
the Amphipoda, and as it contains full references to all species described and published
