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. B. Shaw 1962In order to separate these lower, uncoiled, and presumably more primitive forms from the higher, slightly coiled and presumably more advanced forms, the genus Scenella is here split into two subgenera. For the less primitive forms we may recognize Scenella (Scenella), with S. (S.) reticulata Billings, 1872, as subgenotype, and for the more primitive forms Scenella (Protoconchoides), n. subgen., with Scenella hermitensis Resser, 1945, as subgenotype. Table 2 summarizes the principal features of the species discused below.
