Siphocypraea
Taxonomy
Siphocypraea was named by Heilprin (1897) [Sepkoski's age data: T Mi-l R]. It is extant. Its type is Cypraea problematica.
It was reranked as Akleistostoma (Siphocypraea) by Schilder (1968).
It was assigned to Akleistostoma by Schilder (1968); to Cypraeidae by Perrilliat (1992); and to Neotaenioglossa by Sepkoski (2002).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| 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. |
