Agathotoma merlini is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.[1]
Description
The size of the shell varies between 5 mm and 8.5 mm; its diameter 3 mm.
The solid shell is very elongated and has a fusiform-subcylindrical shape. The spire contains 8 whorls; the first ones smooth and convex, the others slightly convex. The suture is appressed. The sculpture consists of longitudinal ribs, narrower than their intervals, 10 on the body whorl, and with excessively fine striae, visible only with the aid of a lens. The aperture is narrow, measuring less than half the total length of the shell. The columella is a little excavated at the top, slightly twisted at the base. The outer lip is smooth on the inner side, with a sinus on top and inflected below the sinus. The color of the shell is white with deciduous yellowish areas. The last three whorls show a brown subsutural zone, interrupted by the lower extremities of the ribs, which remain white. The columella is tinged with a dark brown color.[2]
