Type locality.

"Sandwich Islands" (Hawaiian Islands).

Type material.

Lectotype: NHMUK 1961175, designated by Kay (1965) (coll. H. Cuming). Paralectotypes: NHMUK 1961176, 3 specimens (see Remarks), Hawaiian Islands (coll. H. Cuming) .

Original description.

Shell elongately pyramidal; whorls twelve to fourteen, spirally carinately ribbed, ribs three, central one much the smallest, a rib of same size at the sutures; canal tubular, enclosed. Colour white, marked with spots and longitudinal flammules of light yellowish-brown.

Diagnosis.

Lectotype 13.5 mm high. Shell conical with flat whorls. Apical part of the lectotype broken off, the visible teleoconch has 14 whorls with three very weakly tubercles to smooth spiral cords. The second cord develops near mid-shell height and remains small until the last whorl. A fine smooth suprasutural cord is slightly visible. Growth lines are visible in the interspaces. The peristome shows a posterior sinus and additional spiral cords. The base has three more weakly tubercled spiral cords. Protoconch missing. Teleoconch background colour white with brown flammulae, siphonal canal brown.

Remarks.

Kay (1965) reported four paralectotypes in lot NHMUK 1961176, but only three are now present. A 9 mm specimen that was measured by Kay is missing, as also noted by Kathie Way in 1983 on labels accompanying the lot.
