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 up to 7.2 x 1.8 mm, turriculate, solid, white, with 14-16 whorls. Protoconch ca. 2-3 whorls, the nucleus moderately protruding; protoconch whorls very convex, sculptured with very strong, sharp, slightly oblique ribs.
Teleoconch whorls sculptured with strong and sharp subsutural and suprasutural knobs, arranged so as to form two spiral rows and loosely defined, oblique axial ribs; both series of knobs starting simultaneously on the first teleoconch whorl, the suprasutural knobs bordered adapically by a definite spiral line. Body whorl not narrowing; its abapical surface smooth and circled by a faint keel on which the axial sculpture abuts.
Aperture with a hardly flaring peristome. Siphonal canal short, slightly narrowing towards its opening, inside with columellar and labial lamellae moderately close together. Anal canal very short, pointing laterally.

This species differs from all others on the North Atlantic seamounts by its short, very strongly sculptured protoconch, and rough sculpture of the teleoconch.  [details]
