Genus Myrtina n.gen.

TYPE SPECIES. — Myrtina porcata n. sp. (here designated).

ETYMOLOGY. — Myrtina diminutive of Myrtea .

DIAGNOSIS. — Shells small to medium in size, relatively flat, sub-circular, dorsal anterior margin with more or less elevated commarginal lamellae. Sculpture of fine to prominent, closely spaced, commarginal lamellae. Radial ribs absent. Lunule lanceolate to heart-shaped, asymmetric with larger part in right valve. Two cardinal teeth in left valve and single tooth in right valve; indistinct lateral teeth present in both valves. Anterior adductor scar short, detached for about 1/5 of length. Pallial line entire. Shell margin smooth.

REMARKS

Alucinoma Habe, 1958 is similar in outline to Myrtina n. gen. but the type species, A. soyae Habe, 1958 , from Japan, lacks hinge teeth and the thin commarginal lamellae are prominent largely on the posterior and anterior dorsal margins of the shell.
