Eucithara capillata is a small sea snail, a marine gastropod mollusk in the family Mangeliidae.[1]
Description
[edit]The length of the shell varies between 5 mm and 8 mm.
The shell has an oval-fusiform shape and is acuminate at both ends. The shell is rather thickened and is of a dull crystalline white color. The 4 to 5 top decurring striae are tinted brown on their ridge. These striae are rather fine. The shell is sculpted by vertical and decurrent ribs. These number 8 to 9 at the penultimate whorl. They are thick, prominent and low,. They are weak at the suture, where they originate, swell towards the middle of the whorl , where they form (seen in profile) an obtuse angle, and terminate only at the base of the shell. The short and acuminate spire contains about 7 whorls, separated by a linear sinuate suture. The embryonic whorls are missing from the samples received; The upper whorls present a slightly convex profile, obtusely angular towards the base. The penultimate whorl is convex, the angulation occurs in the middle. The body whorl measures 2/3 of the total height. The dorsal part is mottled with pale yellow, and, on the last rib below the angle, one can see 3 dots of a slightly tinted fawn color. The aperture is semi-oval, directed slightly obliquely. The peristome is continuous; The inside is enamelled brilliant white. The very oblique columella is rectilinear, remarkably furrowed by a dozen folds. The outer lip has a convex profile, rather bulging, and is flexibly arcuate in the plane of the opening; It is thickened on the last rib. The sinus, situated obliquely a little below the suture, is rounded, and not deeply entering into the thickness of the outer lip.[2]
Distribution
[edit]This marine species occurs off New Caledonia, the Loyalty Islands, the Philippines and Queensland (Australia).
