Popis

Shell small; ovate-lanceolate; turreted. Colour ochraceous-yellow, irregularly spotted with white. On the subsutural ridge are large square spots, spaced at six to a whorl, and alternating with dark chestnut spots. Whorls seven and a half. Suture impressed. Protoconch of a whorl and a half, smooth, and slightly bulbous. Fasciole impressed, distinct, bounded on each side by a stout ridge, having prominent tubercles arranged about twelve to a whorl. Anterior to these on the last whorl are seven prominent spiral cords, the interstices of which carry one or two minute threads. All these are crossed by fine growth lines. Sinus rather wide and shallow. Lip simple and thin. Pillar slightly twisted. Length 20 mm., breadth 6 mm.

Možné záměny

This is distinguished from E. quoyi by beaded lyrae, and from E. philipineri by smaller size, more slender shape, fewer beads to a whorl, and fewer, wider-spaced spirals

Zajímavosti

Apparently Beddome substituted this for E. philipineri when he sent a parcel of Tasmanian shells to Tryon for illustration in the Manual. Instead of the usual interpretation of a single species, Tryon recognised three species, as I do, in this group ; but under the name of monile he figured quoyi, philipineri he called quoyi, and torquata he figured as philipineri.
