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 and Vokes included American and Indo-Pacific species in
Haustellum, which differs from
Murex sensu stricto by lacking a labral spine. Petuch introduced
Vokesimurex for the American long-canalled
Haustellum sensu Vokes, such as
Murex messorius Sowerby, 1841. Houart 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.
