Brachycythara
''Brachycythara'' is a genus of very small predatory sea snails, marine (ocean), marine gastropod mollusks in the family (biology), family Mangeliidae. Description (Original description) The shell is small, stout and biconic. The protoconch is small-tipped, consisting of about 3 very rapidly enlarging Whorl (mollusc), whorls. The body whorl is sculptured with crowded, protractive, curved, axial riblets. The Aperture (mollusc), aperture is long and narrow. The base of the shell is barely emarginate. The anterior canal is not differentiated. The outer Lip (gastropod), lip is not varicose, except at intervals corresponding to axial ribs. The anal notch is shallow. Specimens with a perfectly formed outer lip show a low denticle below the notch well within the aperture. The parietal callus is moderately thickened adjoining notch. The sculpture consists of axial ribs, barely overridden by fine spiral threads, and of microscopic frosted spirals. Brachycythara is a genus of small, biconi ...

Brachycythara Biconica
''Brachycythara biconica'', common name the biconic top turrid, is a species of very small sea snail, a marine gastropod mollusk in the family Mangeliidae. Description The length of the shell varies between 4 mm and 6 mm. (Original description) The shell has a biconic shape. Its color is whitish, with a narrow spiral band of brown at the summit of the whorls, which is darker between the ribs, and a similar wider band a little anterior to the periphery of the body whorl (or some specimens may be described as pale brown, with a spiral band of white on the periphery of the whorls, and as white anteriorly). The shell shows strong transverse rounded ribs, about nine on each whorl, and excessively fine spiral rather distant raised lines, which are obsolete on the summits of the ribs. The protoconch is acute. The spire has the outlines nearly rectilinear. It contains six whorls, subangular, with a moderately impressed suture. The aperture is narrow. The outer lip is oft ...
