Diagnosis
ReferenceDiagnosis
R. L. Squires 2013Shell up to height 42 mm. Protoconch high, conical, multi-whorled (up to four whorls), and smooth (see Wrigley, 1938, pl. 4, figs. 12, 19). Teleoconch up to eight and one-half whorls. Ornament weak to strong. Varices can be present and can be somewhat aligned in posterior canal region. Posterior canal narrow, variable length, ascending along right side of shell toward apex, can cover apex, and commonly continues short distance onto dorsal side of shell. Outer lip simple, unflared, rarely with medial indentation, and reflected (if stromboid notch not present) with gutter (channel) along adaxial margin. Anterior end of gutter can have tongue-like depression that can be coincident with hook-like projection; anterior end rarely abruptly terminated. Stromboid notch commonly absent; if present, commonly prominent but can be variable in strength of development. Siphon moderately wide and short, outer side can be pointed. Siphonal canal with siphonal fasciole (Bandel, 2007, p. 124; herein).
