Leucosyrinx Xenica

''Leucosyrinx'' is a genus of sea snails, marine gastropod mollusks in the family Pseudomelatomidae.WoRMS (2011). Leucosyrinx Dall, 1889. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=138611 on 2011-03-11

Description

(Original description) The thin shell is white or pale without color pattern. The anal notch lies behind the periphery or at the suture. The sculpture is delicate and consists of spiral keels or threads and often oblique riblets on the shoulder of the whorls. The peripheral keel, if present, is not recurved. The operculum is thin, nucleus apical, scar of attachment small. The larval shell is glassy, rounded or keeled. The other shell characters are as in ''Pleurotoma''. The species type is ''Pleurotoma verrillii'' Dall.

This group is intended to contain the operculated species of ''Pleurotomida'' which are so characteristic of the archibenthal region. They are distinctly contrasted with the coarse, spotted or maculated shallow-water species of Pleuroma proper, by their thin, white, delicately sculptured shells. They are apart from ''Drillia'' by having no subtubular projection of the anal notch when adult and no thick varix to mark their maturity. They are separable from the archibenthal Drillias also by their larger shells, longer siphonal canal, and more inflated habit. The anal notch is generally wider, more rounded and nearer the suture than in the typical ''Pleurotoma'', and the operculum proportionally wider and more delicate.
