First maxilliped with terminal joint peculiarly widened at the base. First and 

 second peraeopods of the female with exopods, third and fourth pairs with 



exopods very rudimentary. Fifth peraeopods apparently 



wanting.

1. S, spinulosa Stebb. 1912 S. spinulosus, T. Stebbing 

 in: Ann. S. Afr. Mus., v. 10 v p. 162 t. 60. 



Surface spinulose. Pseudorostral lobes slightly up- 

 turned, without sinus of antero-lateral margin. Carapace 

 narrowly oval, with median keel running for some distance 

 backwards from the small eyeless eyelobe, and behind the 

 middle of the carapace's length flanked by a pair of raised 

 ridges. Fifth pedigerous segment not wider than the pleon. 

 Telson about */7*^^ of the peduncle of the uropods, the 

 margins serrate and behind the middle having 3 pairs 

 of lateral spines. First antenna with P*^ joint much 

 longer than 2'^*^ and 3^ combined, principal flagellum 

 4:-jointed, accessory 3 -jointed, about 

 Second antenna 4-jointed, the slender 

 4*^ joint as long as the stout P*. 

 Third maxilliped with 2^^^ joint not 

 distally expanded and 5*^^i also nar- 

 row. Peraeopod 2 slender, 2"*^ joint 

 slightly shorter than rest of limb, 

 needle-like 7'^^ about thrice as long 

 as 6*^', both combined scarcely as 

 long as the well spined d^^\ Third 

 and fourth peraeopods much shorter 

 than the second, their 2"*^ joint car- 

 rying a minute 2-jointed exopod. Of 

 fifth peraeopods no trace. Margins 

 of uropods serrulate, endopod */5*^'^ 

 as long as the peduncle, its l^^ joint 

 about twice the 2"*^ and 3*^ combined, 

 spines on the medial margin respec- 

 tively 10, 3, 1; the exopod, with P^ 

 joint little more than ^5*^''^ of the 

 2"*^, reaches nearly to the middle of 

 the endopods 3"^ joint. L. 12 mm.

Carapace broad, depressed, without antero-lateral angles. Pleon long 

 and slender. Telson with three apical spines. Eye wanting. Antenna 1 

 with both flagella well developed. Antenna 2 of female 4-jointed, Palp of 

 first maxilla with two filaments. First and second peraeopods in female with 

 exopods, third and fourth pairs with microscopic two-jointed rudiments. Fifth 

 peraeopods rudimentary. Pleopods wanting in both sexes.
