Remarks. Maxillary palp and telson as in the kergueleni form. In uropod 3 both 

 margins of the inner ramus and the inner margin of the outer ramus in the S bear 

 plumose setae; the inner margins of both rami of uropod 1 are also plumose. 



Distribution. Antarctic and sub-Antarctic regions.

Occurrence: 1. St. 5. Tristan da Cunha. 9 $<$ n— 13 mm., 13 $$ 9-14 mm. (shore). 



2. Ditto. 2 immat. $$ 7 mm., 1 $ 10 mm. (from stream through settlement). 



Remarks. Only the fully adult SS show the indented palm as figured by Chilton, 

 younger specimens have an even palm as figured by Stebbing. 



Some specimens from Tristan da Cunha have been for some years in the South 

 African Museum (Reg. no. A 2941, coll. Benomi, 1904), and I identified them with 

 platensis. They were, however, too mutilated to make the identification certain. The 

 present specimens confirm the presence of this species (which does seem to be widely 

 distributed) on this island where it was first collected by Capt. Carmichael. 



Chilton (1921) suggests that there was probably an error in the label (20 fathoms) 

 attached to the specimens from the Maldive Archipelago (Walker, 1905).
