Transition to teleoconch distinct, marked by axial indentation, change in shell color. Teleoconch large (to 67.8 mm), of up to 5 smooth, evenly ovate whorls, with indistinct shoulder, abutting suture. Axial sculpture of fine growth lines, irregular rugae near suture. Spiral sculpture of closely spaced cords. Aperture large, narrowly elliptical, with short, broad, siphonal canal. Outer lip may be slightly reflected, thickened along margin. Inner lip with glossy parietal callus, long columella, siphonal fold. Neither siphonal fasciole, nor pseudoumbilicus present. Periostracum thin, tightly adherent. Operculum large (~0.65 AL), long, narrow, with terminal nucleus at end of strongly curved anterior margin. Columellar muscle very short (~ ½ whorl). Foot with deep propodial cleft. Head large, with short neck, large black eyes at base of broad, tapering tentacles. Buccal mass large, filling proboscis. Odontophore shorter, radula longer than buccal mass. Rachidian teeth long, narrow (L/W ~2.5), Y-shaped, with 3 stout, radially oriented cusps, central cusp longest. Lateral teeth with 3-4 cusps of similar length along innermost 2/3 of basal plate. Salivary glands large, right larger than left. Gland of Leiblein large, ascinous. Oesophagus thick, broad. Stomach U-shaped, lacking posterior mixing area.
