Shell with about eight whorls which are but slightly rounded, but which are separated by a very deep, sharply defined suture; sculpture consisting of rounded longitudinal ribs, and these are cut by shallow, revolving grooves into low, irregular nodules; aperture ovate-elongate, narrowed and turned back below. Color whitish, with a faint, revolving brown band below the suture and another on the base of the shell. Length, 3.5; diameter, 1.5 mm.

As Columbella mystica:
Shell small, slender, solid, pale brown (faded ?) with a smooth nuclear whorl and a half, and four and a half subsequent whorls; suture distinct, whorls well rounded; spiral sculpture of (on the spire two, on the last whorl four) prominent cords near the periphery with wider interspaces, and smaller close set threads on the base and in front of the suture; axial sculpture of (on the last whorl about a dozen) rather feeble rounded ribs with narrower interspaces, these extend more or less obviously over the whorl; aperture ovate; outer lip thin, denticulate within, inner lip smooth, canal short, strongly spirally threaded, slightly recurved. Length, 4.3; diameter, 1.5 mm. U. S. Nat. Mus. Cat. No. 108321.
Off Georgia, one specimen.
Aesopus filosus Angas (= Columbella plurisulcata Reeve) from Port Jackson, Australia, is somewhat such a shell as this, and is referred by Tryon to Atilia. But if C. suffusa as indicated by Pace is the type of Atilia, the present species can hardly be referred to the same group. Without more material and investigation of what the Australian shell involves, I hesitate to give a new sectional name.
