Crustacean Fauna of South Africa. 273 
Telson subtriangular, apex slightly hollowed between 2 minute 
projections. 
First antenna in both sexes, Ist joint with 2 recurved spines at 
base on inner surface, and 1 on apex, 2nd and 38rd more slender, 
flagellum equal to 2nd plus 8rd peduncular joints, 6-jointed. 
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, 
with in small specimens up to 2°5 mm. a well-marked tooth on lower 
margin about 3 from base or sometimes nearly in the middle, in 
other and larger specimens without a tooth and much more sparsely 
setose, flagellum 5-jointed, not as long as 5th peduncular joint ; 
in 2 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 shorterthan 
Ath with 1 (or 2) spines, flagellum shorter than 5th joint, 3-jointed. 
First and 2nd gnathopods as figured by Della 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 Della 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. acherusicum, but 1st 
not so spinulose; third uropod with peduncle broader than long, 
ramus oval, equal in length to the breadth of the peduncle. 
Length: ¢ upto4mm.; 2 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 band 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.) $6 and ovigerous 99. (S.A.M. Nos. A3377 and 
A384:3.) 
To this species also I am inclined to ascribe a single 2 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. lec. p. 75.) I prefer to leave open the question of the 
identity of this specimen until more material, consisting of both ¢ g 
and 2 2, comes to hand.
