From the figures here given I think there will be no doubt as to the identity of these 

 specimens with Pfeffer's species. Though Pfeffer says it is the commonest Amphipod 

 in South Georgia, there is only the one lot from that locality. 



Pfeffer did not mention or figure any accessory flagellum; it is present as a i-jointed 

 articulated rudiment on the present specimens. I do not consider this an insuperable 

 difficulty, in view of the agreement in other features. If the accessory flagellum were 

 absent in Pfeffer's specimens, they would be referable to Pontogeneiella, both species 

 of which have long telsons, but the shape of the head and the postero-inferior corner 

 of pleon segment 3, and the gnathopods, especially gnathopod 1, are conclusive against 

 this assumption. Moreover Chilton when examining Pfeffer's material found the 

 accessory flagellum was present (1912, p. 499) though he did not state this fact in his 

 1913 paper (p. 58). 



These specimens show no resemblance to australis, Miers, or the Challenger specimens 

 referred by Stebbing to Miers' species (which identification I think may be taken as 

 correct, contrary to Walker's opinion 1907, p. 33). Whether australis, Miers, should be 

 put into the synonymy of austrina, Bate, need not concern us here. The shape of the 

 gnathopods of austrina (Bate, 1862, pi. xxvi, fig. 4) is distinctly more like those of the
