Lissospira
''Lissospira'' is a genus of sea snails, marine gastropod mollusks in the family Skeneidae. Description This genus was proposed for a group of deepwater species which had been erroneously referred to ''Cyclostrema''. They are small, thin, of rather delicate texture (with the exception of '' Lissospira rarinota''), opaque white, and slightly lustrous. Their shell consists of few convex whorls forming an elevated spire, with a relatively large, prominent nuclear whorl and a large body whorl. The suture is deep. The umbilicus is small, deep, and does not show any whorls. The aperture is somewhat oblique, circular with a slight sutural angle, and not modified by the body whorl to which the simple, continuous peritreme is but slightly attached. The aperture often has an indistinct thread just within the inner lip, fading out above and below, so that it extends but about halfway round the aperture. It is much nearer the edge along the columellar margin than at the ends and is evide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lissospira Ornata
''Lissospira ornata'' is a species of sea snail, a marine gastropod mollusk in the family Skeneidae.Rosenberg, G. (2012). ''Lissospira ornata'' (A. E. Verrill, 1884). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=532980 on 2012-09-01 Description The diameter of the shell attains 2.6 mm. This species agrees in form and condition of the umbilical region with the ''Lissospira dalli''. But it is very peculiarly marked on the base by thin, impressed lines, running obliquely and crossing the concentric spiral lines at a large angle, so as to produce a sort of "herring-bone" pattern as shown in the figure.
