Veprecula
''Veprecula'' is a genus of sea snails, marine gastropod mollusks in the family (biology), family Raphitomidae. Description (Original description) This genus has been created by Melvill in 1917 for a series of deep-water species of ''Clathurella'' with several peculiarities. The small, thin, delicate shell has a pale brown or white, fusiform Spire (mollusc), spire, either very attenuate, or pagodiform, or broader, and ventricose, always much suturally impressed. The shell contains 10-12 Whorl (mollusc), whorls with 4-5 whorlsin the protoconch. The first of these is smooth, the second to the fourth or fifth are very finely longitudinally radially costulate. The remainder are either few or closely ribbed, crossed by frequent or more distant lirations, acutely echinate at the points of junction, interstices appearing deeply seated, almost smooth, quadrate or oblong. The Aperture (mollusc), aperture is oblong. The outer Lip (gastropod), lip is thin. The sinus is deep and wide, sit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Veprecula Vepratica
''Veprecula vepratica'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. Description The length of the shell varies between 3.5 mm and 12 mm. (Original description) The small, thin, slender shell is fusiform and prickly. The spire is pagodiform. Its colour is uniform pale brown.

Ten sharp projecting radial ribs, interrupted by the broad anal fasciole, ascend the spire obliquely. Along the periphery of each whorl runs a broad spiral shelf, beneath it are two similar but lesser spirals, the lowest of which is half buried in the suture, and above it are three rapidly and successively diminishing spirals. These radials and spirals enclose deeply sunk lozenges, at the point of intersection upwardly directed prickles arise. The anal fasciole is marked with crescentic striae. On the ba ...

Veprecula Hedleyi
''Veprecula hedleyi'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. Description The length of the shell attains 3 mm. This species differs from its congeners in its greater ventricosity and roundness of the whorl. The number of longitudinal ribs on the body whorl is sixteen in the specimen figured. The spiral acute lirations are also more frequent than obtain in Veprecula sykesii or Veprecula vepratica. The four apical whorls are microscopically longitudinally costellate. The holotype possesses a greater number of ribs than obtained in the more recently collected examples, but the author cannot further separate them specifically. Distribution This species occurs in the Gulf of Oman and Réunion Réunion (; french: La Réunion, ; previously ''Île Bourbon''; rcf, label= Reunionese Creole, La Rényon) is an island in the Indian Ocean that is an overseas department and region of France.

Veprecula Pungens
''Veprecula pungens'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. Description The length of the shell attains 9 mm. This species partakes of the general aspect of Veprecula arethusa but is distinguishable from it by its longer spire, narrower form, closer reticulation, and smooth apical whorls.
