形態描述

[编辑]

The shell grows to a length of 4 cm, with conspicuous flattened, cup-like scales interspersed by small, regular rows of nodules. The colour of the shell is pale to greenish, flecked with purplish-brown markings (often encrusted with light pink coralline algae). The 螺厣 is smooth to faintly granular with pale green centre. (Richmond, 1997).

The solid, imperforate shell has a depressed-turbinate shape with a diameter greater than the altitude. It is covered with an irregular spiral series of nodules and granules, of which the subsutural series and two on the median portion of the body whorl英语body whorl are more prominent. The spire英语Spire (mollusc) is depressed, dome-shaped with an apex that is frequently eroded and red. The shell contains 4 to 5 whorl英语Whorl (mollusc)s, the last very large. The large 殼口 is round and iridescent within. The wide columella英语Columella (gastropod) is flattened and excavated, deflexed recurved and somewhat channelled at its base, The inside of the 螺厣 is flat, greenish and golden, iridescent, with about 5–6 whorls and a subcentral nucleus. Its outside is convex, greenish, sparsely granulate all over.

The species is subject to a wide variation. The passage from the strongly tuberculate forms into those in which the transverse striae simply cut the lirae into diamonds or granules is made by imperceptible degrees.[3]
