Many specimens of Clanculus tonnerrei (G & H Nevill 1874) have been misidentified as belonging to this species, following a misidentification of Issel (1869) (Herbert, 1996).[2]

Description

The height of the shell attains 7 mm.

(Description by Philippi) The small, conical shell is perforate, and transversely striate. It color is white, radiated with rose. The shell is angular below the suture, the angle nodose. The body whorl is carinated in the middle. The base is rounded. The aperture as high as wide. The throat is striated. The columella is arcuate, terminating in a bipartite tooth at the base.

(Further description by G.W. Tryon) There are 5 whorls. Above the shoulder angle there are two shallow spiral furrows. Between this and the peripheral carina there are 4, of equal breadth to the elevated interspaces; and on the base about 12.[3]

Distribution

According to Philippi, this species was found in the Red Sea. According to the World Register of Marine Species this is probably not correct,[2]

gollark: Anyway, obviously the round earth is a superior technical solution, but you can bodge the flat-earth thing into *kind of* working and the patent issues make it much cheaper.
gollark: No, a point is dimensionless.
gollark: Round things were patented, so they can't use oblate spheroids without paying the ruinous royalties.
gollark: Most physics treats them as point masses or weird probability-clouds.
gollark: The government also operates light catapults, of course, for certain situations.
