Crustacean Fauna of South Africa. 155 
With regard to the present specimens, in spite of the absence of an 
adult g¢, I have no hesitation in assigning them to this species. The 
flagellar joints of the antennae are a little fewer in number (15 in both 
antennae), but otherwise the agreement is exact, down to the orna- 
mentation on the 2nd joint of the ramus of the 3rd uropod. 
This last character and the much less strongly expanded 4th joint 
of peraeopods 3-5, as well as the hand and finger of the 2nd 
gnathopod in the @, will serve to distinguish this species clearly 
from S. adhaerens Stebbing. 
In S. crenulatw Chevreux has described the mandibles as having in 
the place of the palp a small setiferous tubercle. The same peculiarity 
is found in the present specimens, but the tubercle is sharper pointed 
than in Chevreux’s figure and bears a seta at its base. 
Length : Ovigerous 2? 5 mm. 
Colour : Whitish, eyes rather indistinct. 
Locality: Durban. July, 1915. (H. W. Bell-Marley.) 1 ovigerous 
? and 3juv. (8.A.M. No. A3846.) 
Geogr. Distribution: Ceylon (Walker) ; Gambier Archipelago, 0-25 
metres (Chevreux: crenulata) ; Seychelles, 36 fathoms, and Zanzibar 
(Walker). 
S. spinitmana Chevreux (Mem. Soe. Zool. Fr. vol. 23, 1910, p. 197, 
text-fig. 7 and pl 12, figs. 1-12), from Algeria appears closely allied to 
this species.
