Eucithara nevilliana
Eucithara nevilliana is a small sea snail, a marine gastropod mollusk in the family Mangeliidae.
Description
The length of the shell attains 5 mm, its diameter 2.5 mm.The shell is subfusiform and solid with an obtuse apex, characterized by a uniformly white coloration. It consists of 5 to 6 convex whorls separated by an impressed suture. The sculpture is notably robust, featuring a combination of coarse ribs and spiral grooves that intersect to give the shell a distinct cancellated appearance.
The aperture is high and narrow in form. The columella is curved and exhibits a somewhat rough texture. The peristome is slightly thickened and bent inward over the aperture; its edge is uniquely serrated, a result of the prominent external spiral grooves reaching the margin.
