Shell elongately turreted, rather solid, white, reddish-brown or chocolate, variegated with blue, black, and brown; whorls 9, having four spiral rows of numerous small beads or grains, smooth between; base convex, spirally striate; back of last whorl with a prominent white varice, some specimens showing it more to the right and left of the centre; sutures somewhat deep, aperture roundly ovate, outer lip simple, arcuate ; columella slightly twisted towards the base, canal short.
Long 5, 5,5, 6, broad 1,75 mm. One specimen.
This is one of the most variable species that T know. Some specimens are all white ; others are white with a tinge of pink and with spiral brown lines at the base ; others are of a dark brown or reddish-brown and spotted with white on the grains; others again are white with a blue-black band at the sutures and base. Mr. Henn and I found it rather numerous in shell sand from various parts of Middle Harbour, in good condition. It is one of the species overlooked by Mr. Angas (J. B.).
