Melanella necropolitana is an extinct species of sea snail, a marine gastropod mollusk in the family Eulimidae.
According to WoRMS, the generic placement of this species remains unassessed and is therefore uncertain.
Description The length of the holotype of the shell attains 7.5 mm, its diameter 2 mm.
(Original description) The moderately large shell is elongate-conic, and slender, with a perfectly straight-sided spire. The shell contains 13 whorls. The first two whorls are moderately rounded and separated by a well-marked suture, while the remaining whorls are flattened, with a scarcely impressed suture. The periphery of the body whorl is angulated. The base is moderately long and well rounded. The aperture is oval; the posterior angle is acute; the outer lip is angulated at the junction of the outer and basal lips; the inner lip is oblique, curved, and slightly revolute, being reflected over and appressed to the base posteriorly; and the parietal wall is covered with a thin callus.
Distribution Fossils of this species were found off Deadman's Island (San Pedro), California.
