Description


The shell is claviform with a tall spire, or squatly conical to biconical. In many species, the siphonal canal is truncated. The aperture is U-shaped with a parietal callus pad.


The sculpture of the shell shows prominent axial ribs with a polished surface. Most species have a dorsal varix (transverse elevation), except in the genera Cymatosyrinx, Elaeocyma and Splendrillia. The protoconch can be smooth or very carinate. The ovate operculum has a terminal nucleus.[3]


The radula of the species in this family have characteristically five teeth in each row (formula : 1 + 1 + 1 + 1 + 1) with a vestigial central tooth, comb-like lateral teeth and a pair of flat-pointed, slender marginal teeth.[4]


The foregut structure of the anterior alimentary system has the least derived foregut anatomy of all the families in the superfamily Conoidea.[5]



Taxonomic history


The genera in this family were originally separated from the subfamily Clavitulinae and classified by H.& A. Adams (1858) under subfamily Turritinae, because their operculum has a terminal instead of a central nucleus. In 1942, the species with a U-shaped sinus and a parietal callus pad were brought by Powell in the new subfamily Clavinae. In 1966, Morrison proposed the subfamily Drillinae ( = Clavinae) for the species with a stenoglossan radula with comb-like lateral teeth. Finally, in 1993, Taylor et al. proposed the promotion of Drillinae from subfamily to the family level Drilliidae.[3][6]
