ARTICLE XXVL-THE CRUSTACEA OF THE SUJ^ANTARCTIC 

 ISLANDS OF NEW ZEALAND.

University of New Zealand. 



INTRODUCTION. 



The collection of Crustacea actually made during the expedition was not very- 

 extensive, owing to the fact that very little dredging could be done, and that 

 the Campbell Island station, where I spent most of my time, was not a favourable 

 one for the littoral and marine forms. I have, however, been able to examine 

 and incorporate in this report numerous species that were gathered at other 

 times by Captain Bollons, Professor W. B. Benham, and Dr. L. Cockayne. To 

 these gentlemen and to the various members of the expedition who so willingly 

 collected Crustacea for me at places inaccessible to myself I wish to record here 

 my best thanks. 



No separate list of the Crustacea from these islands has. so far as I am aware, 

 hitherto been published, though several species have been recorded from them at 

 different times by the various scientific expeditions that have visited antarctic seas, 

 by the late Captain Hutton,* and by the late Monsieur Henri Filhol.f In this 

 report I record the occurrence at these islands of seventy-five species — viz., 

 Decapoda, 12 ; Stomatofoda, 1 ; Amphipoda, 34 ; Isopoda, 20 ; Tanaidacea, 1 ; 

 Nebaliacea, 1 ; Entomostraca {Cirripedia, Copepoda, and Branchiopoda), 6. It 

 will be seen that the greater number belong to the Amphipoda and Isopoda. 

 Doubtless many other Decapoda would be added as the result of systematic 

 dredgings round the islands. No proper attempt has yet been made to collect the 

 Entomostraca. 



In the general classification I have followed that adopted by Dr. W. T. Caiman 

 in his recent work on the Crustacea for Ray Lankester's " Treatise on Zoology," 

 while in the Amphipoda I have mainly followed the classification in Stebbing's " Das 

 Tierreich Amphipoda," though with some slight modifications. 



The forms not hitherto described are few in number. I describe only one new 

 genus and nine new species ; but, on the other hand, I have reduced a much greater 

 number both of genera and of species to the rank of synonyms, for reasons that I hope 

 will be considered satisfactory. This I have done chiefly in the Amphipoda, for 

 which group I have fortunately been able to consult most of the reports on the
