Original Description
Small, but not very fragile; low dextral trochospire, tight parallel to axis, fairly loose perpendicular to axis. Equatorial outline circular, weakly lobate; lateral outline compressed, weakly umbilicoconvex. Chambers ovate, weakly appressed, at least 12 (16?) in total, in final and second-last whorls; increase slow but regular until last 2 or 3 when it is reduced. Dorsal view: chambers longer concentrically, very weakly inflated towards anterior; sutures weakly depressed; intercameral sutures directed anteriorly, smoothly recurved posteriorly. Ventral view: chambers moderately inflated, meet only near coil; intercameral sutures thus smoothly and quickly separate proximally and distally, leaving a wide umbilicus. Lateral view: smoothly rounded; aperture interiomarginal, umbilical--extraumbilical, very low. Wall surface smooth, microperforate?, with small to large, widely and irregularly spaced pores on ventral and, in early whorls, dorsal surfaces.

Size: Length, 120 µm; width, 115 µm; height, 50 µm.

Etymology: Greek, piestos, pressed, compressible.
