The ¢ and ? specimens from South Africa referred to by Stebbing 
(1c. 1908, p. 84) are very near to the form described by Stebbing in 
1888 as A. kergueleni. The 1st gnathopod in ¢ has no setae on 2nd 
joint, nor tooth on anterior margin, 4th joint projects beyond end of 
5th, inferior margin of 5th and 6th and apex of 6th with long setae, 
finger 3 length of 6th, inner margin feebly serrate. Fifth peraeopods 
lost. Rami of 38rd uropod subequal and a little longer than peduncle. 
Telson broader than long. 
Littoral specimens from Table Bay are similar. The spine on inner 
apex of 6th joint of Ist gnathopod of ¢ appears to be usually absent. 
Fifth and 6th joints of 2nd gnathopod of g¢ rather narrower than in 
Stebbing’s figure of A. kergueleni, nearly 3 times as long as wide. 
Peraeopod 3 with 2nd joint tapering distally, hind margin straight 
or slightly concave, infero-posterior angle with 1 spine; 2nd joint of 
4th peraeopod similar but rather more pyriform; 2nd joint of 5th 
peraeopod broadly oval, nearly as broad as long, hind margin convex, 
postero-inferior angle with 1 spine. 
The peculiar feature of these specimens is the length of the rami of 
the 8rd uropod, which are equal to or even insomecases a little shorter
