2nd joint longer than 1st, not subequal as in C. sulcata, Hansen. 

 Flagellum not quite as long as peduncle, 12-jointed. 



Second antenna reaching posterior margin of third peraeon 

 segment, rlagellum longer than peduncle, 25-jointed. 



Upper lip, distal margin strongly emarginate, setose. 



Mandibles, maxillae and maxillipeds normal. 



First peraeopod, inner apex of 3rd joint with 1 blunt tubercle, 

 outer apex of 4th joint with 2 small spines and inner margin 

 with 8 blunt tubercles, inner margin of 6th joint with 4 low 

 rounded bosses and small spines between them. 



Second peraeopod, inner apex of 3rd joint with 3 blunt 

 tubercles, outer apex with 2 strong spines, outer apex of 4th 

 joint with 1 strong spine and inner margin with 10 blunt tubercles, 

 inner margin of 6th joint smooth with 4 small spines. 



Fourth to seventh peraeopods, as in C. sulcata, second joints not 

 enlarged nor furnished with natatory setae. 



Uropods, both branches a little longer than telson, inner angle of 

 peduncle extending half-way along inner branch, inner branch with 

 inner margin furnished with 11 short spines with short plumose 

 setae between them, apex subacute not bifid, the outer margin at 

 the apex very slightly emarginate, outer ramus with 3 short spines 

 on inner distal margin and 2 on the outer, apex subacute, slightly 

 bifid. 



Length : 15 mm. ; breadth: 6 mm. 



Colour : Whitish, with grey stellate specks. 



Locality : Sea Point, near Cape Town. 15/11/13. (K.H.B.) 5?? 

 with embryos and 3 very young specimens just hatched. Low-tide, 

 beneath stones and encrusting algae. (S.A.M. No. A2614.) Some 

 specimens taken out of crevices in an old piece of iron wreckage 

 were completely rust-red in colour. 



This species at first sight resembles C. sulcata, Hansen, but is 

 abundantly distinguished by the following characters : the orna- 

 mentation of the peraeon and telson, the marginal armature of 

 the latter, the frontal lamina, the number of antennal joints, the 

 number of tubercles on the anterior peraeopods, and the uropods. 

 The specific name refers to the undulate appearance of the margins 

 of the telson.
