NOTE ON HIPPOMEDON KEBGJJELENI, MIERS, AN 

 AMPHIPOD RECEIVED FKOM CAPE ADARE, 

 SOUTH VICTORIA LAND. 



By G-eo. M. Thomson, F.L.S , Corresponcliug Member of 

 Royal Society of Tasmania. 



In June of this year I received from Mr. A. Morton several 

 specimens of an Amphipod crustacean secured by tlie 

 " Southern Cross " expedition at Cape Adare, South Victoria 

 Land They had been obtained by letting down a baited 

 net through a hole in the ice, but there is no information as 

 to the depth from which they were got. 



The specimens, which are all females, belong to Hippo- 

 nieclon Jcergueleni, originally referred by Miers to Lysianassa 

 (Ann. and Mag. Nat. Hist., vol. xvi., p. 74), and then to 

 Anonyx (Trans, of Venus Exped., Zoology of Kergnelen Island, 

 Crustacea, pp. 8 and 9, pi. xi., fig. 4), but more recently 

 shown bv Stebbing to belong to Boeck's genus Hippomedon. 

 The Rev. T. R. R. Stebbing (Amphipoda of H.M.S. " Chal- 

 lenger," p. 623, pi. viii.) has drawn up a description of this 

 species with that care and minuteness of detail which 

 characterises his work. The specimens received by me differ 

 only in trifling details from his description, but conform 

 more closely to that given by Miers. 



The genus is now credited with five northern and four 

 southern species, but of these, two of Stebbing's Kerguelen 

 Island species aad one Australian are founded on single 

 specimens, and the former two may yet have to be merged 

 into H. Jcergueleni.
