Description

(Original description by M. Schepman) The height of the shell attains 5 mm, its diameter 6 mm. The thick, depressed shell has a low conoidal spire. It is broadly umbilicate, Its color is greenish-yellow. The top

s and a band round the umbilicus are brown. The lower whorls contain a row of large brown blotches at the suture. The

body whorl The body whorl is part of the morphology of the shell in those gastropod mollusks that possess a coiled shell. The term is also sometimes used in a similar way to describe the shell of a cephalopod mollusk. In gastropods In gastropods, the b ...

has at the periphery a zone, articulated by oblong brown squares, alternating with yellow spaces. The upper and lower surface are more or less distinctly variegated with brown flames and spiral dots of the same color. The 5½ whorls are separated by an impressed suture. They are rather convex and slightly angular by the projection of one of the numerous lirae. These number about 6 on the penultimate whorl, and 7 on the upper part of the body whorl, besides several intermediate, elevated striae, which become very numerous towards the

aperture In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. An opt ...

. The body whorl is angular at the periphery. Its convex base has numerous, crowded, elevated striae (partly wanting in a few specimens). The whole surface of the shell is covered with radial striae, crossing the lirae and giving them a beaded appearance, especially near the suture and the umbilicus, where they form regular folds. The umbilicus is pervious and funnel-shaped. Its wall contains flat spiral lirae, crossed by much more crowded, radial, elevated striae, separated by a conspicuous angle from the basal surface. The aperture is subquadrate. Its upper margin is slightly curved, but less so than the basal one. The columellar margin is nearly straight, joining the basal margin with an angle, at the end of the umbilical angle, slightly crenulated by the umbilical lirae. The margins are connected by a thin nacreous layer. The interior of the aperture is nacreous, smooth, and slightly thickened near the margins.Schepman 1908-1913, The Prosobranchia of the Siboga Expedition; Leyden,E. J. Brill,1908-13
