Platycythara Elata
''Platycythara elata'', common name the elongate mangelia, is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. Description The length of the shell attains 4.75 mm, its diameter 2 mm. (Original description) The small, elongated, narrow shell is translucent white with streaks and lines of dark brown or yellow. The first whorl of the protoconch is minute, tilted glassy. The subsequent whorls are translucent, smooth, or with oblique transverse sculpture which almost imperceptibly passes into the ribbing of the adult. In all there are seven whorls including the protoconch. The early ones are rounded, and soon take on an angulation just in front of the fasciole. The spiral sculpture consists of three or four fine threads on the fasciole, and three or four stronger threads between the fasciole and the suture in front. On the body whorl there are fifteen or twenty of these between the shoulder of the whorl and the front end of the siphonal canal. ...

Platycythara Curta
''Platycythara curta'' is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. Description The length of the shell is 2.3 m, its diameter 1.5 mm. (Original description) The small, short, solid, inflated shell has a brownish color,. The minute protoconch is smooth. It is succeeded by about three subsequent strongly sculptured whorls. The suture is distinct. The axial sculpture consists of (on the penultimate whorl about 15) narrow, sharp, similar riblets with wider interspace. This sculpture extends over the base. The spiral sculpture consists of (on the body whorl The body whorl is part of the morphology of the shell in those gastropod mollusks that possess a coiled shell. The term is also sometimes used in a similar way to describe the shell of a cephalopod mollusk. In gastropods In gastropods, the b ... about 16) even regular similar threads with subequal interspaces which pass over but do not nodulate the ribs. The aperture is narrow ...
