as wide, without tubercle at distal end of pectinated edge ; dactylus with six teeth 

 including the terminal one.* 



Epipodites are present on the first five thoracic limbs. 



Free thoracic somites with well-marked submedian and intermediate carinae not 

 ending in spines. Fifth somite with lateral processes undivided,! acute, and strongly 

 curved with the points turned directly forwards. Lateral plates of sixth and seventh 

 somites acutely pointed. 



Abdominal somites with well-marked carinae ; lateral carinae ending in spines on 

 all the somites, the intermediate on the last four and sometimes on all, and the 

 submedian on the fifth and sixth and sometimes on the fourth. Telson resembling 

 that of *S. empusa ; four to eight denticles between submedian teeth, nine to eleven 

 on each side between submedian and intermediate, and one between intermediate and

lateral. Marginal thickenings rather less evident than in S. empusa, those at bases 

 of denticles more or less confluent. A short but prominent post-anal keel. Exopod 

 of uropods with six or seven spines on proximal segment. 



Pigmentation resembling that of S. africana, Caiman (1916, p. 373, figs.),J but 

 with the marginal lines on the somites darker and more sharply defined, the blotch 

 on the exopod of the uropods Jess extensive, and, in addition, a pair of dark spots near 

 the base of the telson at the sides of the median crest. 



Remarks. — It seems probable that the specimens described above belong to the 

 same species as the young male recorded by Bigelow (1894, p. 529) from the same 

 region (ofi" Cape Frio, 59 fathoms), and regarded by him "with some hesitation" as 



* In one specimen the raptorial limb of one side has seven teeth. 



f In one specimen the lateral process of one side is forked.
