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. Williams 1951||Exterior.--Subquadrate, unequally biconvex, the dorsal valve more so than the ventral, accentuated by the very strong median dorsal fold and the complementary ventral sulcus ; ornamented by 28 costae and strongly developed concentric lamellae. Delthyrium closed except apically by a deltidium bearing a median, acutely triangular fold.
Ventral interior.--Teeth widely set, simple, supported by short but strong dental plates. Muscle scars obscure. Plug of the apical foramen preserved as a short curved rod situated at the apical end of the umbo.
Dorsal interior.--Notothyrial platform absent, cardinal process massive, forked ; brachial processes well developed, divergent ; teeth sockets small. Adductor muscle scar rather obscure except for the curved antero-lateral ridges of the posterior adductors.
