If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

A. Lamont 1935Shell sub-semicircular, plano-convex; maximum width near hinge-line; cardinal angles not produced. Ventral valve gently convex, with small sharp beak subtending hingearea which lies nearly in plane of valve. Interior of ventral valve: the teeth are short triangular thickenings fused to the hinge-line; diductor scars indistinctly bounded, flabelliform, divergent, about quarter the length of the valve; adductors small, indistinct, separated by fine median ridge. Surface of valve with fine regular radial threads—about 10 threads in a width of 1 mm.—which are bent back laterally, and one strong median rib. There is extremely fine concentric striation. A few concentric rugae are present, strongest at a little less than half the length of the radii. Dorsal valve almost fiat; beak inconspicuous; hinge-area very narrow. Fine radial ornament. Interior with delicate anterior walls to dental sockets curving back almost parallel with hinge-line; cardinal process of two divergent lobes (Fig. 2).
