Shell small, solid, short-conic; spire acute, with a constricted suture and about seven whorls; color pale-brownish over a white chalky substratum; suture not appressed or channeled, with (on the last whorl, twenty-one) faint, narrow, low, flexuous plications in front of it, which become obsolete on the periphery; the incremental lines, though almost microscopic, are sharp, close, regular, and elevated, forming a distinct feature of the sculpture; spiral sculpture of small, flat fasciculi of four or five threads each, the fasciculi separated by deeper grooves about half the width of a fasciculus; this sculpture requires a lens to make it out and is quite uniform over the surface; aperture wide, white; outer lip expanded, reflected, and thickened, somewhat excavated behind; body with a thin white callus; pillar short, twisted, not pervious; canal wide, short recurved, forming a moderately distinct fasciole; operculum thin, the nucleus midlateral or nearly so.
