Eulimella Explained

Eulimella is a genus of sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.[1] [2] [3]

The subgenus name Ptycheulimella Sacco, 1892 or Turbonilla (Ptycheulimella) Sacco, 1892 has been used to describe species whose shells show a weak fold on the columella and frequently a brownish spiral band. Van Aartsen decided not to subdivide Eulimella s.l. because of the uncertainty of the identification of the type species of this subgenus compared with Tornatella pyramidata Deshayes, 183

Description

Many species are poorly known. The elongated, turriculate shells are small, mostly under 1 cm. They are somewhat glossy and show no sculpture except a few microscopic growth lines. The teleoconch has numerous whorls. The apex is sinistral. The aperture is subquadrangular. The outer lip is not continuous. The columella is straight, without plications. They lack a columellar tooth.

The animal has short tentacles. The mentum, a thin projection below the mouth, is lobed in front. The anterior extremity of the foot is truncated.[4]

This family was described by Peñas A. & Rolán E. in 1997[5] and again in 2000.[6] Van Aartsen et al. gave in 1988 a stable nomenclature of the genus[7] [8]
