3. St. 123. South Georgia. 2 $$ 12 and 15 mm., 12 immat. 7-1 1 mm. 



4. St. 140. South Georgia. 11 immat. and mutilated, up to 12 mm. 



5. St. 148. South Georgia. 1 $ 8 mm. 



6. St. 149. South Georgia. 1 ovig. $ 14 mm., 1 immat. 11 mm.. 1 juv. 8 mm.

Remarks. Unlike the Terra Nova specimen, the medio-dorsal tooth on pleon seg- 

 ment 1 is distinctly larger than any of the other denticles on that segment ; those on 

 segments 2, 3 and 4 increasing in size, that on segment 5 being rather smaller and more 

 slender than that on segment 4. In other respects agreeing with the Terra Nova 

 specimen. 



Although there seems to be considerable variation in the dorsal denticles, the shape 

 of the 5th and 6th joints of gnathopods 1 and 2 precludes this species from being con- 

 fused with serrata from Kerguelen.
