Gibbula concinna, Dunker.

[unclear: Pilsbry,] op. cit., p. 230, pl. xl., figs. 8, 9.

Alsbhell plentiful at Funafuti and which I also saw at Nukulailai, seems [unclear: Qthough] not agreeing exactly, to be nearest this. The page 405sculpture and, except for a white apex, the colour, is like that of G. danieli, Crosse, from which it differs by a crenulate umbilical margin. The largest is 71/2 mm in diameter and has an umbilicus 11/2 mm. broad.

G. concinna is known only from Upolu, Samoa.
