Anomia, sp.; a few disassociated upper valves, not specifically recognisable, were gathered on the lagoon beach of Funafuti.
Arca zebra, Swainson;... Abundant under stones at low water in the lagoon. In this Museum there are specimens from Trinity Bay, Queensland. It is doubtful whether A. occidentalis, Philippi, is distinct. If not, the species has a circumequatorial range. Arca maculata Sowerby... One living specimen obtained in the lagoon. First found by Cuming at Marutea, in the Paumotus. Specimens are in this Museum from Aneiteum, New Hebrides.
Arca reticulata, Gmelin.... Several disassociated valves of this world-wide species were. observed on the lagoon beach. The synonymy and range of this species have been examined at length by Lischke.
