Eurymera monticulosa, Pfr. (Fig. 118 b). 



Pfeffer, 1888, p. 103, pi. i, fig. 3. 



Chevreux, 1906, p. 59, figs. 34-36; 191 3, p. 167. 



Chilton, 1912, p. 493. 



Shoemaker, 19 14, p. 74. 



Occurrence: 1. St. 174. South Shetlands. 1 ? 23 mm. 



2. St. 179. Palmer Archipelago. 46 <$S and ?? up to 20 mm., 3 juv. 6-7 mm. 



Remarks. Integument coarsely pitted all over. 



Distribution. South Georgia; Graham Land, littoral; South Orkneys, 4 fathoms. 



Genus Pontogeneia, Boeck. 

 Schellenberg, 1929 a, p. 277; 1931, p. 181. 

 The number of simple unexpanded flagellar joints on antenna 1 separating every two 

 of the dilated joints which bear sensory filaments appears to be a good specific cha- 

 racter, but only in adult animals. Compare the adult and young of tristanensis {infra). 

 Other characters should of course be utilized in conjunction. 



Pontogeneia simplex (Dana) (Fig. n&g). 



Dana, 1853/55, P- 9 2 ^» pi- l x i n > %• 2 - 

 Bate, 1862, p. 140, pi. xxvii, fig. 2 (after Dana). 

 Chilton, 1912, p. 495 (danai, non Thorns.). 

 Schellenberg, 193 1, p. 182, fig. 93. 



Occurrence: St. 56. Falklands. 1 immat. $ 11 mm., 1 ovig. $ 14mm. 



Remarks. Integument minutely shagreened, with scattered pits. Every 5th or 6th 

 flagellar joint on antenna 1 enlarged and bearing sensory filamentous setae. Flagella of 

 both antennae more thickly spinulose than in antarctica, Chevr. 



In the present state of our knowledge I prefer to identify these specimens with 

 Dana's species originally collected at Hermite Island than with a New Zealand species. 

 They are in all probability adults of the same form as Chilton examined. 



Distribution. Hermite Island, Cape Horn; Falkland Islands. 



Pontogeneia georgiana (Pfr.) (Figs. 118 h, 119). 



Pfeffer, 1888, p. 116, pi. ii, fig. 6 (Calliopius g.). 

 Stebbing, 1906, p. 308 (Apherusa g.). 

 Schellenberg, 1929 a, p. 278; 1931, p. 184, fig. 94. 



Occurrence: East Cumberland Bay, South Georgia. 1 ? 13 mm., 2 muti- 

 lated $?. 



Remarks. Although Pfeffer said that, next to Schraderia gracilis, 

 this was the commonest Amphipod in South Georgia, there are only 

 these three specimens in the present collection. 



They entirely conform with Pfeffer's description. The postero- pig. 119. Pontogeneia 

 inferior angle of pleon segment 3 is not mentioned in the description georgiana (Pfr.). Head.
