Magilus antiquus, Lamarck.

Tryon, loc. cit., p. 216, pl. lxviii, figs. 400-411.

Two young shells were obtained alive in company with the Galeropsis just mentioned. Tryon's remark "that all the species that have been differentiated from M. antiquus must be regarded with suspicion," has guided my determination. Nothing seems to be recorded of the distribution of this species in the Central Pacific. A specimen from the Solomon Islands is in this Museum.
