Crustacean Fauna of South Africa. 121 
as a narrow, subacute, upwardly curved lobe, scabrous and setose, 
palm transverse, slightly sinuous; in J slightly preduced as a blunt, 
rounded lobe. 
Third to fifth peraeopods, hind margin of 2nd joint slightly serrate. 
Second uropod, rami more slender than in Stebbing’s figure. 
The wpper posterior angle of 5rd pleon segment as well as the lower 
posterior angle is rounded. This forms a ready mark of distinction 
between this species. and the other South African species L. variegata 
(Stimpson), which has the upper angle somewhat acute. The telson 
and the 3rd uropods are also distinguishing features between the two 
species. 
Length: § 13 mm., ovigerous ? 14-17 mm. 
Colour: Whitish, semipellucid, with a faint pink or pale brown 
tinge dorsally, sometimes with a brown dorsal patch on peraeon seg- 
ments 1-3 and 7 and a brown transverse band between pleon segments 
land 2 and 2and 3. Eyes black.

Geogr. Distribution: Caribbean Sea (Stebbing); Cape Town and 
Saldanha Bay, 0-25 fathoms (Chilton). 
In the character of the 3rd uropods and Ist antennae the South 
African specimens certainly approach the Mediterranean L. bispinosa, 
and with more material from other localities it might be possible to 
unite L. cubensis with the latter.
