Descrição original:

(Pilsbry, 1895): “Shell nearly imperforate, ovate, solid and strong; part roseate, part white under a yellow cuticle. Surface having inconspicuous growth-lines, a fine, shallow malleation, and dense, microscopic spiral striation. Whorls 4 3/4, the first planorboid, the last obliquely descending.

Aperture oblique, small and narrow, somewhat over half the shell’s length, white inside; peristome reflexed, recurved, thick, rounded on the face, rose-color, but white at the outer-basal portion; there is a perceptible thickening at the middle of the outer lip, but no tooth. Columella roseate, narrow below, reflexed and recurved, hardly widened above, and foldless.

Parietal callus heavy, rose-colored toward the margin, white within, the white extending upon the inner, upper part of columella. Alt. 53, diam. 28 mill.; aperture measured outside peristome, alt. 28, width 18 mill. Brazil (J. G. Anthony).

Differs from Strophocheilus pudicus in the micro-sculpture, thick lip and narrow aperture; from planidens and milleri in the malleation, etc. It is more nearly allied to unidentatus, which has the same sculpture, but the spire is slenderer and more produced, mouth narrower, lip not dentate and differently colored.”
