Original description: Shell broadly conical, trim, and with sharp collar stricture; apical horn, short, conical, base as wide as length; cephalis subhemispherical, very short (not over 0.3 length of shell), generally slightly asymmetrical with swollen sides, its basal diameter greater than its altitude, collar distinctly set off from thorax below it; thorax dome-shaped with greatly swollen sides, its greatest diameter reached at or near its middle, symmetrical, and very neat and trim; legs three, equal, equidistant, strong, divergent, curved inwardly and hollowed out... with expanded bases; wall relatively thick, uniform, with depressed areas whose elevated edges appear in edge view as surface projections; surface of apical horn, hyaline; of cephalis, without pores; of thorax, with numerous well-spaced, subcircular, elongate-oval, squarish or even subhexagonal pores, these pores double-contoured, generally uniform in size except for a very few, odd scattered small ones; framework around the aperture not dense and connecting the bases of the feet with a narrow, hyaline collar with a basal row of reticulations at the thoracic margin.
