Shell seven-whorled, the nucleus lost, the fragment of it remaining is smooth and colored like the rest of the shell, a pale straw color; spiral sculpture (1) of a large undulate thread, or continuous series of undulations, flat behind, sloping forward, sixteen or seventeen on the whorl next to the last; these give the whorl a turrited appearance; (2) of a strong simple thread revolving a short distance in front of the suture and forming the posterior margin of the fasciole; (3) of a dozen or more similar threads on the last whorl, extending from the periphery, where the interspaces are wide, to the canal, where they are narrow; on the first three whorls of the spire none of these threads are visible; on the whorl next the last there are two between the suture and the shoulder of the whorl; transverse sculpture of rather strong, even, irregularly spaced, concavely arched waves, which cross the fasciole from side to side like a succession of irregularly huddled parentheses; also of a few faint ridges on the base due to incremental irregularities. Base subconic, slightly constricted for the canal; notch wide, squarely cut, rounded at the bottom, not touching the suture, a little deeper than wide; outer lip arched forward, thin, not lirate within; inner lip smooth, simple ; pillar straight; canal short, wide, very slightly recurved, leaving a fasciole behind the pillar which is slightly obliquely trimmed off anteriorly; aperture long, narrow, shorter than the spire. Max. lon. of shell, 10.2 mm; of last whorl, 6.0 mm; lat. of shell, 4.0 mm.

Caribbic: Dominica. Northward to South Carolina.

The sculpture of this shell is of remarkable elegance ; its general form recalls Genota, but the aperture is rather short for that group.
