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. Liljeborgia kinahani (Bate) (Fig. 81). Sars, 1895, p. 532, pi. clxxxviii, fig. 1. Stebbing, 1906, p. 233. var. capensis n. Occurrence: St. 90.
