PARAPHRONIMIDAE 267 



7. St. 38. South Georgia. 3 ?$ 15-18 mm. 



8. St. 44. South Georgia. 8 $$ 14-18 mm. 



9. St. 169. South Orkneys. 1 ? 13 mm. 



10. St. 208. South Shetlands. 1 ? 11 mm., 2 ?$ (with uterine ova) 16-17 mm - 



Remarks. In addition to the marked difference in shape between the 2nd joints of 

 peraeopod 5 of this species and magellaniciis , there is a submarginal keel running from 

 the articulation of the 2nd joint with the body parallel with the front margin to the 

 insertion of the 3rd joint; in magellaniciis the outer surface of the 2nd joint is quite 

 smooth. 



Like magellaniciis this species migrates to the upper layers during the night. There 

 are no actually ovigerous ??, and no $£ in the collection; but several ?$ contain what 

 seem to be uterine ova, and it would seem that the breeding season starts towards the 

 end of April or in May. 



This is a more southerly form than magellaniciis, not being found north of lat. 53^° S. 



Distribution. South Georgia; 65 S, 8o° E.

Stewart's paragraph (1913, pp. 253-254), stating that the $ has a longer mandibular 

 palp than the ?, is evidently misplaced as neither sex in this genus has a mandibular 

 palp.
