Diagnosis. Aragonitic shells, many with a chalky intritacalx. Small to quite large. Most with prominent varices, often bearing spines or webbing, spines simple or ramose. Nuclear whorls usually 2 or less in number but with numerous exceptions. Operculum unguiculate. Central radular teeth generally with three large cusps and two smaller cusps between them. 

Remarks. In the Good Old Days of Carl, everything was a Murex. Those days quickly came to an end. The Muricinae constitute most of the large, showy members of the family, including the famous Murex pecten. Unlike the Trophoninae and Ocenebrinae, which have nearly world-wide distributions, the Muricinae are primarily tropical. 

Overall, the Muricinae comprises the greatest range of sizes, shapes, and sculpture of any muricid subfamily (and nearly any family of Gastropoda). It is unlikely that they are all closely related - future splitting may be required.
