Description

Shell white, slender conical. Embryonic whorls planorbid, with a diameter of 250-300 µm. Teleoconch consisting of six to seven flat whorls which are relatively high with respect to their width, and are separated by a moderately deep suture. Growthlines inverted-S-shaped, about orthocline. Without additional sculpture. Mouth oval. Outer lip nearly straight adapically and evenly curved lower down. Without an umbilicus. There is a prominent fold on the columella.
Dimensions: H. 3.5-4.3 mm, W. 1.0-1.2 mm; holotype 3.6 x 1.0 mm.

Interchangeable taxa

This species may be confused with Eulimella digenes (Dautzenberg & Fischer, 1896) but its shell is more slender, with perfectly flat whorls and a clear fold on the columella, absent in E. digenes. Compared with E. cerullii Cossman, 1915, E.fontanae spec. nov. has much smaller protoconch whorls and one whorl more in shells of the same length.
Depth range.— 400-620 m.
