The maximum recorded
shell length is 40 mm. (Description of
Amauropsis purpurea) The shell is elongate-globose, coated with a yellowish epidermis, and exhibits a purple-brown hue that weathers to a purplish-white tone. It comprises four inflated, globose
whorls with a deeply canaliculated suture. The
aperture exceeds half the length of the shell and is ovate in shape. The outer
lip is thin, while the
columella is white, thickened, and smoothly rounded. A thin
callus lines the inner lip. The
umbilicus is either closed or reduced to a mere chink. The
spire is very short and bluntly rounded. The shell’s surface features numerous closely spaced, fine revolving grooves interspersed with a few faint ridges, adding a subtle texture to its otherwise smooth appearance. ==Distribution==
