Beu & Maxwell (1990): Chapter 17; p. 390; pl. 57 d.
Classification: Pyramidellidae: Turbonillinae
Description: Height 2.7-9 mm, turriculate, spire moderately to greatly elevated. Protoconch helicoid, initial whorl not greatly projecting. Teleoconch whorls flattened to gently convex; no sculpture apart from growth lines, and in some species, very fine spiral striae. Aperture ovate, columella straight or slightly concave, some species with a weak posterior swelling, but no definite plait.
Comparison: Eulimella is distinguished from Syrnola by not having a definite columellar plait, and from Turbonilla and Chemnitzia in lacking axial costae. Terelimella Laws, 1937 also lacks axial costae, but differs in having a planorboid protoconch, a taller and narrower shell, and more strongly convex teleoconch whorls.
Distribution: Bortonian-Recent, New Zealand; widespread, probably cosmopolitan, Eocene-Recent.
