“Mycale tridens, Hentschel.
M. tridens, Hentschel 1914, p. 56, pl. v, fig. 6; Topsent 1917, p. 63.
Occurrence.—Reg. 93, stn. 314, McMurdo Sound, 222-241 faths.
Remarks.—The only representative is a large, massive sponge, whose surface is thrown into low rounded tubercles, or plateaux, separated by deep meandering grooves. The oscules are trumpet-shaped, very like those of Inflatella belli, about 1 cm. high. The appearance of the sponge, apart from the oscules, recalls the external form of M. lingua, so that although it has not been possible to study satisfactorily the character of the dermal skeleton it is probable that the species belongs to the sub-genus Mycale.
