Description

The length of the shell attains 14 mm.

A small shell of a striking ovate-turreted character with six whorls. The colour of the shell is white, but the nodules on the eight ribs are quite prominent, mostly of a pale yellow colour, but here and there they are ornamented with conspicuous bright brown blotches, sparingly distributed. The aperture is oblong and narrow. The outer lip is thick and denticulate within. The posterior sinus is slightly deep and has a rounded curvature. The columella is upright, turning slightly to the left. The short siphonal canal is anteriorly expanded.[2]

Distribution

This marine species occurs off Japan and Taiwan, the Cook Islands, Society Islands, Fiji Islands and New Caledonia.[3]

gollark: Left-justification:> Left-wing politics supports social equality and egalitarianism, often in critique of social hierarchy.[1][2][3][4] Left-wing politics typically involves a concern for those in society whom its adherents perceive as disadvantaged relative to others as well as a belief that there are unjustified inequalities that need to be reduced or abolished.[1] According to emeritus professor of economics Barry Clark, left-wing supporters "claim that human development flourishes when individuals engage in cooperative, mutually respectful relations that can thrive only when excessive differences in status, power, and wealth are eliminated."[5] No language (except esoteric apioforms) *truly* lacks generics. Typically, they have generics, but limited to a few "blessed" built-in data types; in C, arrays and pointers; in Go, maps, slices and channels. This of course creates vast inequality between the built-in types and the compiler writers and the average programmers with their user-defined data types, which cannot be generic. Typically, users of the language are forced to either manually monomorphise, or use type-unsafe approaches such as `void*`. Both merely perpetuate an unjust system which must be abolished.
