Crustacean Fauna of South Africa. 273 



Telsou subtriaugular, apex slightly hollowed between 2 minute 

 projections. 



First antenna in both sexes, 1st joint with 2 recurved spines at 

 base on inner surface, and 1 on apex, 2nd and 3rd more slender, 

 flagellum equal to 2nd plus 3rd peduncular joints, 6-joiuted. 



Second antenna <$ stout but not greatly enlarged or flattened, 

 about as long as the peraeon plus head, 4th joint twice as long as 

 broad or less, oval, inferior apex with 1 strong tooth and a smaller 

 one above it, 5th scarcely as long as 4th and about half as wide, 

 within small specimens up to 2'5 mm. a well-marked tooth on lower 

 margin about \ from base or sometimes nearly in the middle, in 

 other and larger specimens without a tooth and much more sparsely 

 setose, flagellum 3-jointed, not as long as 5th peduncular joint ; 

 in $ about equal to head plus the first 4 peraeon segments, 3rd 

 joint with 2 (or 3) recurved spines on inner margin, 4th half as long- 

 again as broad, with three spines on inner lower margin, 5th shorter than 

 4th with 1 (or 2) spines, flagellum shorter than 5th joint, 3-jointed. 



First and 2nd gnathopods as figured by Delia Valle for C. 

 acherusicum. 



The other peraeopods also similar to those of C. acherusicum, 

 but 4th joint of peraeopods 1 and 2 not so broad as in Delia Valle' s 

 figure ; 5th joint of peraeopods 3 and 4 with an apically transverse 

 row of 5 spines and a subapical one of 3 spines. 



First and second uropods as figured for C. aclierusicum, but 1st 

 not so spinulose ; third uropod with peduncle broader than long, 

 ramus oval, equal in length to the breadth of the peduncle. 



Length : $ up to 4 mm. ; ? 3 mm. 



Colour : Whitish with brown or blackish mottlings forming trans- 

 verse bands on peraeon segments 1-6 and pleon segments 1-3, these 

 bands usually interrupted dorso-medially, peraeon segment 7 without 

 markings, head with a dark transverse baud between the eyes, 

 which are black, antennae and ventral surface of peraeon also 

 speckled with darker. 



Locality : Durban Bay. March and July, 1915. (H. W. Bell- 

 Marley.) g and ovigerous ? ? . (S.A.M. Nos. A3377 and 

 A3843.) 



To this species also I am inclined to ascribe a single ? from Hout 

 Bay, Cape Peninsula (11/2/14. K.H.B. S.A.M. No. A2865) ; but 

 since the telson appears to be apically acute (cf. Chevreux's figure of 

 C. acutum. 1908. I.e. p. 75.) I prefer to leave open the question of the 

 identity of this specimen until more material, consisting of both rf <$ 

 and $ J , comes to hand.
