Description

Shell of medium size, 30-36 mm. (ca. 1-1,5 inches) in height, of light build, narrowly fusiform, with tall turreted spire, sharply angled medially, narrow aperture and moderately long slightly flexed unnotched anterior canal. Whorls 10,5, including a blunt paucispiral smooth protoconch of about 2 whorls, the top vertically compressed and medially carinate over the last half whorl, followed by several brephic axials. Spire-whorls without a subsutural margining; shoulder area almost straight and steeply descending to a median bluntly angulate periphery. Sculpture of moderately strong short protractively oblique axial folds, 14-15 per whorl, which are restricted to the peripheral area. The whole surface crossed by spiral threads and weak cords. About six threads on the shoulder area, 3-4 cords on the peripheral angle and 3-4 below it. Cords continued over the base and neck and with one or two threads in most interspaces. Sinus moderately deep, occupying most of the shoulder area and confluent below with a forward arcuate swing of the thin outer lip, which contracts gradually below to the anterior canal. Colour cream with two bands of light yellowish-brown, one encircling-the peripheral nodes and the other at about the middle of the base

Interchangeable taxa

This is the species figured by Kira, I960, in "Coloured Illustrations of Japanese Shells", pl. 35, fig. 7. From hirida it differs in the lack of a submargining of the suture, more numerous and protractively oblique, not vertical, axials, the addition of a basal subangle and pale coloration, faintly banded, but differently from lurida, the uppermost band being at the peripheral angle whereas that is the site of the white band in both hirida and kantakurana.
