Description

Shell minute pupiform, vitreous, white, with a yellow-brown row of large nodules just behind the suture; nepionic whorls missing; subsequent whorls six, with a row of small nodules in front of the suture, in front of which is a row of large ones, both white, then the single brown row forming the periphery; the base has three strong spirals, the posterior one somewhat nodulous; aperture contracted; pillar twisted; canal very short, deep; near the apex there are only two rows of nodules between the sutures, and the brown color of the anterior one is feebler.
Length, 2.5; diameter, 1 mm.

Distribution: Texas; Greater Antilles; Bermuda. Size: 4 mm
Description: Color white and orangish-brown alternating spiral beaded cords with top cord white, bottom cord orangish-brown; shape pupoid; sculpture of 2 beaded cords per teleo¬conch whorl; body whorl beads somewhat elongate; beads connected by somewhat concave flattened spiral and axial riblets; aperture subquadrate to ovate; siphonal canal abrupt. Habitat: Calcareous environments at depths from 0 to 101 m (330 ft). Remarks: Rare species; has been collected in Texas only from offshore reefs. Complete specimens with protoconchs rare; however, the sculpture of 2 equally sized spiral beaded cords per whorl with alternating color pattern is quite distinct, which some authors believe to be a true Cerithiopsis. See Ode (1989c); Garcia and Lee (2002).
