Eucithara Explained

Eucithara is a genus of small to quite large sea snails, marine gastropod mollusks in the family Mangeliidae.^[1]

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.^[2]

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 is as long, or longer, than the spire, fortified externally by a stout varix which ascends the previous whorl, includes a semi-circular sinus, and extends a free edge over the mouth. Within the outer lip are a series of short entering ridges, and the columella bears a corresponding series of deeply entering horizontal bars.^[3]

Distribution

This genus has a wide distribution in the Red Sea, the Persian Gulf, the Indian Ocean, the Pacific Ocean, the East China Sea; off Australia (Northern Territory, Queensland, Tasmania, Western Australia).
