I do not do so here for two reasons; first, because I have not seen any specimen of Ophiocten omitimim from the type locality, off Kerguelen—perhaps the Kerguelen specimens will prove to differ from those from South America and be more like the South African form; and then we do not know O. ajfinis from the West African Coast, unless the Ophiocten africamim of Koehler should prove to be identical with affinis (in my Echinoderms of South Africa, p. 391, I have expressed the opinion that it is more nearly related to the Mediterranean O. Griibei, Heller). In view of these uncertainties I think it preferable for the present to designate the South African form as a variety of Ophiocten amitinum, var. simulans, 18-2
