Haustellum
Haustellum is a genus of medium-sized sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails. Like many other genera within the Muricidae, the genus has been redefined several times. Ponder & Vokes (1988) and Vokes (1990) included American and Indo-Pacific species in "Haustellum", which differs from "Murex" sensu stricto by lacking a labral spine. Petuch (1994) introduced "Vokesimurex" for the American long-canalled "Haustellum" sensu Vokes (1990), such as "Murex messorius" Sowerby, 1841. Houart (1999) transferred 14 Indo-Pacific species and three subspecies of "Haustellum" in the genus "Vokesimurex". As currently defined , "Haustellum" is represented by eight to nine species. Members of "Haustellum" generally differ from those of "Vokesimurex" in having a globose and low-spired shape, a more rounded aperture, a smooth columella, a less deep anal notch, and no cord spine. Species. Species within the genus "Haustellum" include: Paleontology. There is no record of extinct species in the geological register. The oldest member is the type species "Haustellum haustellum" from the Indo-Pacific province. It is recorded from the Miocene of Borneo (Beets, 1941), the Pliocene of Java, Indonesia and the Plio-Pleistocene of the Malaysian Archipelago.
