Gymnobela engonia

The length of the shell attains 17 mm, its diameter 3.5 mm. The somewhat solid, white, more or less translucent shell has a stout-fusiform shape. The aperture is about equal in length to the spire, which is shouldered, decidedly turreted, and tapered regularly to an acute apex. The shell contains five whorls below the protoconch, strongly angularly shouldered at about the middle, the portion above the shoulder forming a wide, abruptly sloping subsutural band, which is usually slightly concave in the middle, but swells a little where it joins the suture. The whorls are flattened below the shoulder and a little narrowed at the suture, which is strongly impressed. The sculpture on the subsutural band consists of many, close, revolving lines towards the shoulder, and of small, slightly raised, thin riblets, which are most distinct close to the suture and strongly excurved in the middle of the band, but bend forward to the angle of the shoulder, where most of them disappear or blend with the ribs and lines of growth a little further forward. …

This species occurs off New England, USA and was found off the Nantucket Shoals at a depth of 2941 m.
