The height of the shell attains 3 mm.
The small, white, rather solid, subglobose shell has a depressed-conical shape. The four whorls are a little convex. They are joined by an impressed suture, and ornamented by spiral closely, minutely granulose riblets; The body whorl is rounded at the periphery. The base of the shell is convex, spirally granulate-ribbed, and narrowly umbilicate. The aperture is subrotund. The outer lip is regularly arched, its edge rather
obtuse, and sulcate inside. The columella is straight, obliquely sloping, with a small tooth below.〔(Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia ) (described as ''Euchelus seychellarum'')〕
