. The atoll of Funafuti, Ellice group: its zoology, botany, ethnology, and general structure based on collections made by Mrs. Charles Hedley, of the Australian museum, Sydney, N. S. W. 484 FUNAFUTI Fig. 45. Atys dactylus, sp. nov. (Fig. 45). Shell date shaped, truncated above and below, minutely perforate above, deeply and narrowly umbilicate below. Colour white, glossy. Sculp- ture—from sixty to seventy, irregularly waved, narrow, shallow grooves girdle the shell, between which are smooth, flat topped lyree, two or three times their breadth; these are crossed at irregular intervals by fine and coarse growth lines. The aperture is vertical, longer than the shell, narrowly arched, dilated above and below, rather effuse anteriorly. Above, the lip rises from the centre of the apical crater and folding back almost covers the perforation; the outer lip is straight and simple; the columella broadly reflexed,emarginate without, tuberculate within, a short tongue of callus extends a little distance upwards along the body whorl. Length 4|, breadth 2| mm. One specimen from the lagoon beach. This species appears to approach nearest to A. Jeffrey si, Wein- kauff, from the Mediterranean, which served Monterosato as type for his genus Roxaniella. Cylichna erecta, sp. nov. (Fig. 46). Shell cylindrical, truncated above, bevelled out- wardly round the vertex, rounded below and compressed around the basal axis. Colour white. Sculpture—the only specimen is too worn for exact description ; it seems to have been girt by numerous broad and shallow spiral grooves. Aperture nearly perpendicular; lip produced medially; columella broadly reflected, apparently minutely plicated. Spire umbilicate, a shallow crater into which each whorl descends by steps. Length 4, breadth If mm. A single rather worn example from the lagoon beach. This species appears to be quite distinct from Fig. 46. others of the genus. Those that share the cylindrical shape being C. discus, Watson, more truncat
