Description

The length of the shell varies between 6 mm and 13 mm. The white shell is elongate, slender and cylindrical. It is transversely finely ridged, interstices striated transversely, longitudinally faintly and obsoletely irregularly ribbed. The sutures are bordered on each side by a crenulated rib, the crenulations connected obliquely by a small ridge. 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 ...
