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.
|L. W. Stephenson 1941 (Garramites)||This simple, nearly smooth, trochoid shell resembles Margantes in its general form and wide open umbilicus, but differs from that genus in having an angulated, rather coarsely crenulated, umbilical border. Within the umbilicus a broad, shallow, spiral sulcus closely borders the row of crenulations.|
