Beu & Maxwell (1990): Chapter 17; p. 384; pl. 56 c,g.
Classification: Eulimidae
Description: Height 2-3.6 mm, subcylindrical, relatively solid, spire elevated. Protoconch of about 1.5 strongly spirally keeled whorls. Teleoconch whorls almost flat-sided, gently convex or medially angled; perimeter Of base angled in some species. Sculpture of axial costae, typically flexuous and stopping at peribasal keel. Aperture ovate, outer lip slightly thickened in some species.
Comparison: Coenaculum has previously been referred to the Rissoidae and the Epitoniidae, and was tentatively included in the Aclididae by Beu & Maxwell (1990, p. 384), following Wenz (1940, p. 833) and Ponder (1967, p. 220), but is now referred again to the Eulimidae (Spencer et al. 2009).
Distribution: Waitakian-Recent, New Zealand; Recent, south-eastern Australia. Most New Zealand records of Coenaculum are from shallow-water assemblages, but the genus ranges down to the upper bathyal zone.
