Shell small, translucent white, elongated, with a dark-brown, minutely reticulate nucleus of three small whorls and about a dozen subsequent whorls; suture distinct, not impressed, with a single simple thread immediately behind it; axial sculpture of (on the last whorl 17 to 25) narrow rounded vertical ribs crossing the whorls, with wider interspaces, and very minute regular close-set sharp incremental lines; the base shows the feeble ends of the ribs radiating from the axis; spiral sculpture of (on the last whorl 9 or 10) fine equal simple threads, with usually subequal narrower interspaces, not swollen where crossing the ribs at the intersections; at the periphery of the whorl is an angle or small ridge which appears behind the suture on the spire; the base is flatfish or even slightly concave without spiral sculpture; aperture subquadrate with thin margin, the axis imperforate. Length of shell, 10.5; of aperture, 1.5; diameter, 2.5 mm. U. S. Nat. Mus. Cat. No. 108368.
Off Georgia, 13 specimens.
The flattish whorls and shallow suture recall Opalia.

Another deep water species, found at depths of 400 to at least 700 fathoms, from northern Florida to the Antilles. To 12mm, long, narrow, with about 15-18 degrees angle to spire. It has up to 10 whorls and 4 dark, ribbed nuclear whorls. A yellowish brown color. Axial sculpture consists of numerous low costae, up to 15 on the body whorl. The numerous axial threads do not pass over the costae. Base of the body whorl has a flattened appearance. A somewhat variable species, inviting synonymy.
