Hyperoche medusarum (Krdy.). 

 Stephensen, 1924, p. 79. 



Occurrence: 1. St. 125. South Georgia. 2 <$S 10 and 13 mm. 



2. St. 130. South Georgia. 1 ? 9 mm. 



3. St. MS 30. South Georgia. 1 juv. $ 7 mm. 



Remarks. A species which seems to keep to the upper layers, rarely being found 

 below 250 m. (Stephensen, p. 79). Stephensen erroneously quotes Tattersall (1906) to 

 the effect that it is rarely " encountered at depths greater than 1000 fathoms", whereas 

 Tattersall really says " It would appear to be a wholly littoral and sublittoral form 

 rarely extending outside the 1000-fathoms line". 



It is extremely interesting to find this boreo-Arctic species appearing in the South 

 Georgia area, and likewise in the upper layers not far from land. The only other species 

 of the genus hitherto found in Antarctic and sub-Antarctic waters are : 



luetkenides, Wlkr. South of Australia 



capucinus, Brnrd. South-west of Cape Horn and in Ross Sea 



cryptodactylus, Stebb. Off Cape of Good Hope 



Distribution. North Atlantic and adjacent seas, about 50 -77 N ; North of Alaska. 



Genus Pegohyperia, Brnrd. 

 Barnard, 1931, p. 429. 

 Integument indurated, firm (77^709). Eyes apparently without ocelli or facets. Side- 

 plates uneven, 1, 2, 6 and 7 shallow, 3-5 much deeper. Pleon not abruptly narrower 

 than peraeon (in ?). 



Antenna 1 with large laminate flagellum. Antenna 2 well developed ($). Mandible 

 with "molar" projection laminate as in Hyperoche, and well-developed palp. Maxilla 1 

 with large laminate palp.
