DESCRIPTION OF THE SPECIES. 
Unless otherwise stated, the references to Professor 0. 0. Sars are to his “ Crustacea 
of Norway,” Vol. I., Amphipoda, 1895 ; those to Mr. Stebbing (Rev. T. R. R.) are to his 
£ Challenger ’ Report; and to A. 0. Walker, to the Amphipoda of the ‘ Southern Cross’ 
Antarctic Expedition, Journ. Linn. Soc., London, Zoology, Vol. XXIX. (1903), 
pp. 38-64. 
The classification of the species is, as far as possible, in accordance with that of 
Professor G. 0. 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 Tierreieh.” As this will be indispensable to all systematic.workers on 
the Amphipoda, and as it contains full references to all species described and published
