'''''Finella''''' is a [genus](/source/genus) of [sea snail](/source/sea_snail)s, [marine](/source/marine_(ocean)) [gastropod](/source/gastropod) [mollusk](/source/mollusk)s in the [family](/source/Family_(taxonomy)) [Scaliolidae](/source/Scaliolidae).<ref name="WoRMS">{{WRMS species|138264|''Finella'' Adams, 1860||11 April 2012}}</ref>

This genus has been assigned in the course of time to different families by different authors: [Rissoidae](/source/Rissoidae), [Cerithiidae](/source/Cerithiidae), [Dialidae](/source/Dialidae), [Obtortionidae](/source/Obtortionidae), [Finellidae](/source/Finellidae) and [Diastomatidae](/source/Diastomatidae) Morphological and anatomical studies by [Winston Ponder](/source/Winston_Ponder) in 1994 established that the genera ''Finella'' and ''[Scaliola](/source/Scaliola)'' didn't belong in the above-mentioned families and he brought them in a new family Scaliolidae.<ref>Ponder W. F. "The anatomy and relationships of  ''Finella'' and ''Scaliola'' (Caenogastropoda, Cerithoidea, Scaliolidae)". pp. 215-241. In: Morton B. (ed.)

Proceedings of the Third International Workshop on the Malacofauna of Hong Kong and Southern China; Hong Kong, 13 April - 1 May 1992 xxii + 504 p.; Hong Kong University Press, Hong Kong</ref> This was supported in 1982 by Healy through the study of the ultrastructure on the [spermatozoa](/source/spermatozoa).<ref>Healy J.

==Description==
The species in this genus contain a small, elongated, conical shell without [siphonal canal](/source/siphonal_canal). The axial to spiral [sculpture](/source/Sculpture_(mollusc)) varies between weak and strong.

==Distribution==
The snails of this species are common to even abundant in shallow waters of the tropical Indo-West Pacific Ocean.
