The South African form is the same as that described by Dana a& 

 Cratoplnum validum, having the basal tooth on 6th joint of the 

 2nd gnathopod of <$ distally emarginate on outside and apically acute 

 (see Stebbing, Challeng. Rep. vol. 29, pi. 138). In the ? the projec- 

 tion just distal to the basal tooth, which bears 3 spines, of 6th joint 

 of 2nd gnathopod is angular as in Sars' figure of pusilla, not rounded 

 as in his figure of falcata. 



Side-plate 2 longer than deep, anterior margin scarcely more than 

 half the posterior margin of side-plate 1, posterior margin not as deep 

 as anterior margin of side-plate 3, inferior margin in $ very slightly 

 concave, in 5 straight or very slightly convex. 



There appears to be only one form present in South Africa corre- 

 sponding to Sexton's "Form 2." " Form 1 " with swollen antennae 

 and broad hand and thumb has not yet been discovered. 



Length : 4-6 mm. 



Colour: Greyish, somewhat mottled dorsally, frequently a darker 

 grey dorsal patch on peraeon segments 5-7 and also sometimes on the 

 pleon segments.
