Crustacean Fauna of South Africa. 121 



as a narrow, subacute, upwardly curved lobe, scabrous and setose, 

 palni transverse, slightly sinuous ; in J slightly produced as a blunt, 

 rounded lobe. 



Third to fifth peraeopods, hind margin of 2nd joint slightly serrate. 



Second uropod, ranii more slender than in Stebbing's figure. 



The upper posterior angle of 3rd 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. varieyata 

 (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, seniipellucid, 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 

 1 and 2 and 2 and 3. Eyes black.

 and A2 741.) 



Geogr. Distribution : Caribbean Sea (Stebbiug) ; Cape Town and 

 Saldanha Bay, 0-25 fathoms (Chilton). 



In the character of the 3rd uropods and 1st 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.
