This genus is in an unsatisfactory state. I have not seen Walker's discussion of the 

 variability of the dorsal denticles (Tr. Liverp. Biol. Soc. xxm, 102, 1907). The shape 

 of the epistome may prove to be a useful specific character, but up to the present it has 

 not been incorporated in descriptions, though it is more or less clearly indicated in the 

 enlarged drawings of the head in Sars (1895). This defect should be remedied as soon 

 as possible by some student having access to northern and Australasian material. 



The South African specimen, identified by Stebbing as dubia, another resembling it 

 in dorsal denticulation, and the specimen referred by me to proximo. (1916, p. 167) are 

 in too poor a condition to give any trustworthy evidence on this point. 



It would seem also that the adult S has features of considerable specific importance, 

 namely, gnathopod 2 and peraeopod 5 (cf. Barnard, 1930, p. 365). Very few fully adult 

 SS seem to have been noticed.

Remarks. These specimens all agree with peraeopod 5 (j) of var. falklandica. 

 Sars' figure and the descriptions of the 



northern kinahani as regards the tridentate pleon segments 1 and 2, and the single short 

 decumbent tooth on both pleon segments 4 and 5. The fingers of gnathopods 1 and 2, 

 however, have 7 and 17 serrations respectively; thus considerably more than in typical 

 kinahani. The eyes are well developed, large (as in Chevreux's figure of consanguinea, 

 1913, fig. 25), black. 



Epistome with the projecting keel triangular with an obtuse point in var. capensis, 

 rounded subtriangular in var. georgensis, and oblong in var . falklandica . 



Postero-inferior angles of side-plates 5 and 6 quadrate or slightly subacute, not toothed 

 as in mixta Schell. 



Hind margin of 2nd joint of peraeopod 5 with strong, deeply-indented serrations.
