Description

The shell is small to large (35-250 mm) and fusiform. Its spire is moderately high and acute, consisting of one and one-half or two smooth nuclear whorls and six to nine globose, more or less shouldered postnuclear whorls. The suture is moderately to strongly impressed. The body whorl is moderately large and globose. The aperture is moderately large and ovate, with a shallow, moderately broad anal sulcus. The outer apertural lip is erect and marginally, finely to coarsely dentate; the interior of the lip is generally weakly lirate. The columellar lip is generally detached and weakly erect, with a few prominent elongate denticles posteriorly, these forming the parietal margin of the anal sulcus, and three or four weaker denticles anteriorly. The canal is moderately long to very long and strongly bent to the right. The body whorl bears three more or less spinose varices. The length of the medially open varical spines varies with the species. The varices also develop more or less broad, webbing-like extensions, these better developed in some species than in others.

Interchangeable taxa

This genus seems to have evolved a considerable number of very closely related species. Their similarity has caused a great confusion in identification. Attempts to diminish the number of names have convinced us that these resemblances, especially in the Caribbean forms, are based on generic, rather than specific, characters. Caribbean forms of Stratus differ from those of Murex s.s. in their more globose whorls, notably bent siphonal canal, and varical webbing.
