Antiplanes
''Antiplanes'' is a genus of sea snails, marine gastropod mollusks in the family (biology), family Pseudomelatomidae,. Description (Original description) These deep-water and abyssal forms are smooth except for incremental lines and sometimes fine spiral striae. The periostracum is conspicuous and the shell disposed to be chalky. The anal sulcus is shallow and more or less rounded, usually situated some distance from the suture, but not quite on the periphery of the Whorl (mollusc), whorl. The siphonal canal is rather wide and long and often a little recurved. The Aperture (mollusc), aperture is unarmed. There are both dextral and sinistral species. Species Species within the genus ''Antiplanes'' include: * ''Antiplanes abarbarea'' Dall, 1919 * ''Antiplanes abyssalis'' Kantor & Sysoev, 1991 * ''Antiplanes amphitrite'' Dall, 1919 * ''Antiplanes antigone'' (Dall, 1919) * ''Antiplanes briseis'' Dall, 1919 * ''Antiplanes bulimoides'' Dall, 1919 * ''Antiplanes catalinae'' (Raymond, 19 ...

Antiplanes Catalinae
''Antiplanes catalinae'' is a species of sea snail, a marine gastropod mollusk in the family (biology), family Pseudomelatomidae. Description The length of the shell attains 27 mm, its diameter 7.6 mm. (Original description) The sinistral shell is thin, elongated and slender. It contains 10-11 Whorl (mollusc), whorls. Its color is light, pinkish -brown, without bands. The interior of the Aperture (mollusc), aperture is a little lighter: The upper whorls are more or less chalky. The protoconch is smooth and inflated. The later whorls are convex. The suture is deeply impressed. The shell is sculptured by fine incremental lines and on the last whorls a few obscure, spiral striations, mostly below the periphery. The anal fascicle is traceable on the Spire (mollusc), spire as a flattened or obscurely grooved band. The aperture is narrow. The siphonal canal is wide and short. The Columella (gastropod), columella is nearly straight, with a well-defined callus, obliquely trunc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
