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.
|R. D. Hoare et al. 1972||Small polyplacophorans with intermediate valves wider than long and nearly straight across width. Tail valve triangular in shape, keel extending entire length and lacking a mucro, gently concave or straight lateral slopes which are steeply inclined and underside of posterior portion commonly ridged parallel to valve margin by coalescence of coarse surface granules. Dorsal surface of valves sculptured by fine granules in quincunx arrangement. Head valve and girdle unknown.|
|R. D. Hoare and M. T. Sturgeon 1976||Small polyplacophorans with head and intermediate valves wider than long, nearly straight across width, with ii valve slightly longer than iii-vii valves. Tail valve triangular in shape, keel extending entire length and lacking a mucro, nearly plane lateral slopes which are steeply inclined, underside of posterior portion smooth or with concentric growth lines. Dorsal surface of valves sculptured by fine granules in quincunx arrangement. Girdle unknown.|
