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.

E. J. Petuch 1996 (Calusacypraea)Cvpraeid shells of average to large size, ranging from 35 to 70 mm in length, extremely inflated, thin, delicate, bulliform; apices characteristically very depressed, forming distinct apical pit; posterior edge of lip typically highly-developed, greatly-projecting beyond plane of spire; columellar side of apical area poorlydeveloped, only slightly projecting beyond plane of spire; anterior extremities poorly developed, without distinct projecting beaks; ends of anterior extremities do not extend beyond end of anterior canal, producing rounded, blunt, sheared-off appearance; in some species, anterior extremity on labial side almost absent, with extremity blending into rounded end of lip and giving shell juvenile appearance; bases of shells very rounded; margins of shells poorly-developed, rounded, with only thin enamel deposits; anterior canal thickened, bordered by prominent enamel collar; apertures proportionally narrow, variabK w idening tow ard anterior end; columellar teeth proportionally small, thin, and narrow, extending along length of columella; some species with row of obsolete, secondary teeth developed along anterior end of columella; labial teeth well-developed, confined to edge of lip; tossula nonexistent; color pattern (when preserved) composed of numerous small, closely-spaced dots on dorsum.
