DIAGNOSIS. — Shells small, subcircular in outline. Moderately inflated, relatively thin-shelled. Sculpture of fine, closely spaced commarginal lamellae, sometimes slightly raised to posterior, fine radial stri ations sometimes present. Hinge plate narrow. RV with single cardinal tooth and posterior lateral tooth, anterior lateral absent or very small. LV with two cardinal teeth and a posterior lateral tooth. Ligament internal, set in elongate,oblique resilifer.Anterior adductor muscle scar elongate, detached from pallial line for about 1/2 to 1/3 of length. Pallial line irregularly lobed and divided. Inner shell margin finely crenulate.

DESCRIPTION

Shell white, small, thin, H to 15 mm, circular to subcircular in outline; posterior shell margin slightly truncate. Protoconch 160 µm long, PI smooth, 110 µm, PII with growth increments. Sculpture of extremely fine, low commarginal lamellae with fine radial striae between commarginal lamellae ( Fig. 35E View FIG ).Commarginal lamellae are slightly broader and more elevated near dorsal margins. Lunule narrow, lanceolate to heart-shaped and slightly excavated. Anterior dorsal area often with irregular folds. Hinge plate narrow; RV with prominent cardinal tooth, two small posterior lateral teeth and tiny anterior lateral tooth. LV with two cardinals, anterior cardinal is trigonal and larger, posterior laterals are low and anterior lateral absent. Ligament internal, deeply impressed into each valve. Anterior adductor muscle scar short, broad and detached from the pallial line for about 1/2 of length. Pallial line with irregular lobes and partially divided.Pallial blood vessel impression faint. Surface of shell inside pallial line with indistinct, narrow, radial ridges, shell outside the pallial line glossy with fine radial striations. Shell margin finely denticulate.
