Description

The length of the shell attains 26 mm, its diameter 7 mm. (Original description) The shell is ovate, ventricose, thin, fragile and transparent. The body whorl is very much the largest. The shell is very closely reticulated throughout with fine raised lines, of which the transverse are the stronger. 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 ...

: The protoconch consists of 2½ whorls and is microscopically obliquely reticulated. The body whorl has about forty spiral threads, the penultimate twelve, and so on till the topmost with three is reached. Between the larger threads smaller ones are intercalated, and gradually enlarge till of equal size. The small sharp radials, close set at the rate of about eighty to a whorl, override the spirals and produce beads at the points of intersection. These extend unbroken across the whole shell. The
