Oediceroides macrodactylus, Schell. (Fig. 79). 

 Schellenberg, 193 1, p. 140, fig. 74. 

 Occurrence: 1. St. 42. South Georgia. 3 ?$ 9-1 1 mm. 



2. St. 45. South Georgia. 1 £ 11 mm., 8 $$ 10-15 mm. 



3. St. 123. South Georgia. 30 $$ 9-13 mm. 



4. St. 144. South Georgia. 15 $? 8-12 mm. 



5. St. 148. South Georgia. 4??n-i2mm. 



6. St. 149. South Georgia. 1 $ 10 mm., 3 $$ u-13 mm. 



7. St. 195. South Shetlands. 4 33, 5 ?? 8-10 mm. 



Description. Integument minutely shagreened and pubescent. Head, peraeon and 

 pleon dorsally rounded. Rostrum gibbous, de- 

 flexed, extending to end of 1st joint of antenna 1. 

 Antero-lateral angle of head subacute (as in Par- 

 oediceroslynceus, Sars, 1895, pi. ciii). Eyesapparent- 

 ly well developed, with glistening lenses, but quite 

 white. Side-plate 1 strongly expanded and pro- 

 duced forwards below, 4 moderately excavate on 

 hind margin. Telson subquadrate, distally slightly 

 emarginate. 



Antenna 1, 2nd joint nearly as long as 1st. 



Gnathopod 1, 5th joint broadly lobed below, 

 posteriorly rounded, anterior angle subquadrate. 

 Gnathopod 2, 5th joint produced downwards in 

 the shape of an oblique oblong or plough-share, 

 somewhat similar to that of calmani (see Chevreux, 

 1913, fig. 30 A), and quite unlike the rounded lobe in rostratns or Cinderella. 



Remarks. The characteristic features of this species are the even dorsal profile, the 

 shape of the 5th joints in gnathopods 1 and 2, and the lack of coloured eye-pigment. 

 The rostrum is not more gibbous than in newnesi or calmani. 



The colour of no. 2 is given as "anterior half of body orange-red, remainder and 

 appendages pale yellow, eyes red". 



Genus Methalimedon, Schell.

Methalimedon nordenskjoldi, Schell. (Fig. 80). 

 Schellenberg, 1931, p. 150, fig. 79. 

 Occurrence: 1. St. 27. South Georgia, iovig. $6 mm. 



2. St. 140. South Georgia. 2 ?$ (1 

 ovig.) 6 mm. 



3. St. WS 33. South Georgia. 4 ??7mm. 

 Remarks. This form is very close to Parhali- 



medon turqueti, Chevr., 1906, with which I at 

 first identified the above specimens . They agree, 

 however, with Schellenberg's description.
