Eucithara
''Eucithara'' is a Genus (biology), genus of small to quite large sea snails, marine (ocean), marine gastropod mollusks in the family Mangeliidae. This genus has been a convenient dumping ground for many Indo-Pacific species. A profound study is still lacking and polyphyly probably occurs, as shown by the radulae of the few species examined. Description Species in this genus show a rather solid turreted-fusiform shell, sculptured by bold longitudinal ribs, over-run by dense spiral threads, and decussated by an even finer radial striatum. The Aperture (mollusc), aperture is as long, or longer, than the Spire (mollusc), spire, fortified externally by a stout Varix (mollusc), varix which ascends the previous Whorl (mollusc), whorl, includes a semi-circular sinus, and extends a free edge over the mouth. Within the outer Lip (gastropod), lip are a series of short entering ridges, and the Columella (gastropod), columella bears a corresponding series of deeply entering horizontal bars. ...
