5. Daphnella conquisita, n. sp. Plate IX, fig. 1.

Shell small, fusiform, thin, fragile, semitransparent, spirally lirate. Sculpture consists of narrow, sharply rounded and elevated spiral ribs, narrower than the grooves, 4 on the spirewhorls, 10 on the body-whorl, the interspaces radiately microscopically finely striate. Colour light-fulvous. Spire elevated, higher than the aperture. Protoconch formed by 2 smooth and convex whorls. Whorls 6, regularly increasing, slightly shouldered, flatly convex, base contracted. Suture impressed and margined below by a small thread on the penultimate whorl only. Aperture oblong-oval, margins nearly parallel, produced below into an open, slightly flexuous canal, truncated at the base. Sinus obsolete. Outer lip sharp, inside smooth, convex above, concave on the canal. Columella sinuous, slightly produced in the middle, without any callosity.

Altitude, 6 mm.; diameter, 2·2 mm.

Type to be presented to the Colonial Museum.

A very well characterized species, in sculpture approaching D. lacunosa, Hutt., which, however, has smooth grooves.
