(Jeffreys, 1858)

Description (shell):
Shell tall and slender, with a blunt apex. The shell has about ten slightly but distinctly tumid whorls; though they are slightly tumid the sutures (which lie rather more obliquely than is usual) are extremely inconspicuous. Their position is sometimes made clearer by a white band of shelly material on their abapical side, with the false suture appearing as a dark line below that. Last whorl occupies rather more than half the shell height. The surface shows only a few faint growth lines. Aperture is long (occupies just over a third of shell height), very narrow, its breadth being only about 40 % of its height, with long axis apparently curved. In side view the outer lip is a little flexuous with a shallow anal sinus in its adapical half, a slight bulge in its abapical half.

Size:
Up to 10 x 2.5 mm.

Colour:
Colourless (fresh), white (old and empty).

Animal:
The animal is like that of Eulima species but is blind and has no pallial tentacle. It is white with some brown pigment on the mantle edge.

Habitat:
The animals live, probably with ophiuroids, 70-3000 m deep, on soft bottoms.

Distribution:
Occurs between the Mediterranean and Norway. They are rarely found; local records are few, mainly northern, and, apart from one off Shetland, all of empty shells (Distr. H. stenostoma).
