Biology The type of larval development is not known from direct evidence, but is inferred to be intracapsular from similarity of the larval whorls with those of Cerithiella (see Bouchet and Warén, 1993). There is a multispiral protoconch, but no clear separation protoconch 1/protoconch 2 nor protoconch 2/teleoconch. [details]

Diagnosis Shell very variable in size, up to 20 x 3 mm, turriculate, solid, white, with 13-25 whorls. Protoconch ca. 4-5 whorls, the nucleus moderately protruding; protoconch whorls quite convex, sculptured with strong, sharp, oblique and curved ribs.
Teleoconch whorls sculptured with strong subsutural and suprasutural knobs, arranged so as to form two spiral rows and loosely defined, oblique axial ribs; the suprasutural knobs starting earlier on the first teleoconch whorl. Body whorl not narrowing; its abapical surface smooth and circled by a keel.
Aperture with a continuous, flaring peristome. Siphonal canal moderately long, cylindrical, inside with columellar and labial lamellae not very close. Anal canal small and short, pointing sidewards.
