Scaliola Lapillifera, Sp. nov.
(Fig. 8).

Shell ovate conical, broad for the genus, white, thin and translucent. Whorls seven, rounded, the earlier closely coiled, the later looser, surface obscurely marked by growth striæ. Apical whorls smooth and bare; the rest beset with adherent sand grains more closely disposed about and below the periphery. Aperture round, free from the preceding whorl, with expanded and reflected lip. Length 2, breadth 1 mm.

Three examples from the sandy beach of the lagoon.

This is smaller and proportionately broader than other Scaliola and especially differs by the almost solute whorls. It is less coated with adherent matter than S. caledonica.
