I. INTRODUCTION. 



Shortly after my arrival in Britain in December 1911 I was honoured by a request 

 from Dr W. S. BRUCE, leader of the Scottish National Antarctic Expedition, that I would 

 prepare a report on the Amphipoda collected during the voyage of the Scotia. Dr 

 E. J. ALLEN, Director of the Marine Laboratory, Plymouth, very kindly offered me 

 accommodation in the laboratory for the work, and free access to the library of the 

 laboratory, which, fortunately, is very well supplied with works on the Crustacea. I was 

 assured also of assistance from Mr T. V. HODGSON, the Curator of the Museum and 

 Art Gallery, Plymouth, from Mrs E. W. SEXTON, and from other friends ; and accord- 

 ingly T undertook the work. I received the main portion of the collection, contained 

 in sixty-three bottles, on the 8th January 1912, and a few days later I received from 

 Dr W. M. TATTERSALL of the Manchester Museum eighteen tubes containing additional 

 Amphipoda found among the Schizopoda of the Scottish National Expedition which 

 had been submitted to him for determination ; these additional specimens contained 

 three or four species not represented in the collection first received. 



Twelve tubes of additional specimens from Dr TATTERSALL and many further 

 specimens from the Scotia collection reached me in May. These consisted chiefly 

 of duplicates of species previously sent, but contained also two species not previously 

 seen. Some additions to the report, which had been sent in at the end of March, were 

 therefore necessary. 



With very few exceptions, the Amphipoda proved to have been particularly well 

 preserved, and the localities, depth, and other particulars had been in all cases carefully 

 recorded. I have given full details of these, even at the risk of some slight repetition, 

 as they may prove to be of use in helping to decide questions now unforeseen that may 

 afterwards arise. In several cases, especially among the Lysianassidse, large numbers 

 of specimens of various sizes had been collected from each locality, and these complete 

 sets have been of very great use in helping me to ascertain the changes that take place 

 in some species during the growth of the animal, and in determining the differences
