Chiltou has recorded this species from Salclaiiha Bay, and given a 

 figure of the 3rd uropod, remarking that the keeled peduncle is quite 

 characteristic. Compared with Stebbing's figure, the 3rd uropods of 

 the South African specimens are not so short and stumpy ; they are 

 about intermediate between Stebbiug's figure and Delia Valle's figure 

 of those of L. bispinosa (Delia Valle). In the $ the keel is not so 

 pronounced, and the whole uropod is a little longer than in the ? , 

 the rami are fringed with long setae. In both sexes the outer upper 

 margin of the peduncle, which in Stebbing's specimen was notched, is 

 in the South African specimens entire, as in L. bispinosa. 



The 1st joint of the 1st antennae sometimes has indications of 1 or 

 2 teeth on the apex, but these are never prominent ; the flagellum is 

 8-10-jointed, accessory flagellum 5-6-jointed, equal to half or a little 

 more than half the flagellum. 



Ultimate joint of 2nd antenna a little longer than penultimate, 

 flagellum 9-12-jointed in $ . 



Teeth on apex of palp of 1st maxilla evanescent in large specimens, 

 in smaller ones 6, as described by Stebbing.
