Crustacean Fauna of South Africa,

First uropods measuring 20 mm. from base to apex of inner ramus 
which is fused with peduncle, width of peduncle 5 mm., both margins 
spinulose, length of inner ramus 5 mm., width at base 4 mm. 
Second uropods measuring 15 mm., width 4 mm., inner ramus 
4 mm. long and 3 mm. wide, outer ramus 5 mm. long and 1 mm. 
wide. 
Locality : Buftalo River (East London) NW. by N., distant 21 miles. 
490 fathoms. s.s. “ Pieter Faure.” 22/4/01. (S.A.M. No. A289.) 
The particular features of this species are to be found in the head, 
the mandibles, third and fourth peraepods, and the uropods. 
It is probable that when more material of all the species has been 
collected, an exhaustive comparison will lead to alterations in the 
diagnoses of the species. The other species of the genus are C. spino- 
sum (Fabr.) 1775, C. longipes (Bov.) 1886, and C. loveni (Bov.) 1886. 
Stebbing in 1888 instituted provisionally C. parkinsoni and C. fabricii. 
Bovallius (1889, Le. p. 45) calls attention to the close agreement in 
the measurements of the Challenger specimen F (C. parkinsoni) and 
C. longipes ; the length of the antennae is distinctive, for in all other 
species they are shorter than the head. The locality of Bovallius’ 
specimen (West coast of Australia) is not far removed from that of 
Stebbings’ specimen (North of Amboina). I feel inclined therefore to 
reckon Stebbings’ specimen F (parkinsoni) as a C. longipes. 
The Challenger specimen G might possibly be a C. loveni, but a 
comparison is difficult. In the key given by Bovallius (lc. p. 58) the 
measurements are in fair agreement, but it must be noted that 
Bovallius gives the length of the antennae of specimen G as ‘‘ 1] mm.” 
instead of 20 mm. (Stebbing: 8; inch). Leaving specimen G ( fabrici’) 
out of account, the species may be distinguished as follows : 
Antennae longer than head, 14-18 
teeth on lower margin . . C. lon- 
Peduncle of uropods not twice} —gipes (Bov.). 
the length of rami. . .) Antennae shorter than head, 13 teeth 
on lower margin . .  C. spinoswim 
(Fabr.). 
A row of 6 spines on either side of 
Peduncle at least twice au mouth-parts . C. africanum n. sp. 
length of rami. . . . .) Only 2 spines on either side of mouth- 
parts . . . . OC. loveni (Bov.). 
Unfortunately I have been unable to consult Woltereck’s paper on 
the “ Valdivia” material (1902, Zool. Anz. xxvi. p. 447).
