Argobuccinum
Taxonomy
Argobuccinum was named by Bruguière (1792) [Sepkoski's age data: T Than R]. It is extant.
It was reranked as Ranella (Argobuccinum) by Boettger (1901).
It was assigned to Ranella by Boettger (1901); to Cymatiidae by Durham (1944), Hickman (1980), Kensley and Pether (1986); to Ranellinae by Wilson (1993); to Neotaenioglossa by Sepkoski (2002); and to Ranellidae by Beu (2010).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. S. Terry 1968 (Mediargo) | Diagnostic generic characters that are seen in all butthe largest gerontic specimens include the following: twonearly continuous lateral varices on each volution, highspire, rounded whorls having tabulate shoulders, moderate to long anterior canal, anal notch oriented at anangle to the axis of coiling (as in Fusitriton, in contrastto the apically directed notch in Argobuccinum), transverse pillar folds over most of the columella, and a denticulate or plicate outer lip. Axial and spiral costae maybe marked or obsolete and are commonly present onjuvenile whorls but conspicuously lacking in the laterstages. Mediargo differs from Argobuccinum in its tabularwhorls and anal notch, from Fusitriton in its lateralvarices and plicate aperture, and from Gyrineum in itsoutline, tabulate shoulders, ovate aperture, marked analnotch, and large size. |
