Crustacean Fauna of South Africa. 
of A. recens, 4th and 5th joints with the scabrous lobes small in Ist, 
but large in 2nd gnathopod. 
First and second peraeopods feebly spinulose, 4th and 6th joints 
with spinules on both margins, 5th spinulose only on hind margin, 
finger with a very minute setule on inner apex. 
Third to fifth paraeopods, 2nd joint oval, hind margin with very 
slight setiferous serrations, 4th and 6th joints spinulose on both 
margins, finger with a very minute setule. 
First and second uropods with marginal spines on inner ramus only. 
Third uropod, peduncle with 3-4 apical spines, ramus nearly as long 
but only half as wide, tipped with 5 setae. 
Length: 6 9mm., 2 5-6 mm. 
Colour : In spirit, whitish, eyes dark brown. 
Locality : Salt River, near Cape Town. October, 1898. (Dr. W. F. 
Pureell.) 5 ¢ g, 3 ovigerous ? ? “in brackish pool”; Hast 
London. July, 1914. (R. M. Lightfoot.) 326, 2 ovigerous ? 2 
“found amongst a number of Valorchestia on the beach.” (S.A.M. 
Nos. 10030 and A5053.) 
Geogr. Distribution: New Zealand (Dana, Thomson, Chilton) ; 
Campbell Island (Chilton). 
Thus it will be seen that the only differences between the South 
African and the New Zealand specimens lie in the shorter 3rd joint of 
the 1st antenna, the larger eyes, and the more prominent defining 
angle of the hand of 2nd gnathopod. 
As mentioned above under Talorchestia quadrispinosa, there is one 
specimen 5 mm. long from Salt River which has a normal ¢ Ist 
gnathopod, but a 2nd gnathopod resembling that of the 2. It is, 
however, stouter than in the ?, the 6th joint especially being much 
broader than inthe °.

2? 1843. Orchestia bottae Krauss, Siidafr. Crust. p. 60. (non M. 
Edwards 1840.) 
Male. Body fairly compressed, back rounded. Eyes fairly large, 
round, their distance apart greater than their diameter. Side-plate 1 
smaller than and partly concealed by 2, side-plates 2-4 shallower than 
their segments and longer than deep, upper half of posterior margin 
above posterior angle excavate, 5 as deep as 4. Postero-inferior angle 
of pleon segments 1-3 quadrate, with a very shortly produced point, 
posterior margin quite smooth.
