  • Anchura quitmanensis Stanton, 1947

Original Description of Anchura quitmanensis by Stanton, 1947, p. 104:

  • "Shell of medium size, rather slender, consisting of about 10 convex whorls; apical angle about 25; each whorl with about 15 slightly curved, narrow but prominent costae which rapidly become shorter and broader on the outer half of the last whorl of the adult, until the last 2 or 3 near the expanded outer lip are represented by large tubercles; surface also marked by closely arranged fine revolving lines, of which 15 or more are visible on the spire; aperture moderately long, truncate behind, without any tendency to form a posterior canal; anterior canal rather long and narrow; callus of inner lip not very heavy; posterior portion of outer lip extended in a slender, winglike expansion slightly curved upward (backward) and bearing a well-marked carina extending back across about one-third of the last whorl, giving it a distinctly shouldered appearance; wing and anterior portion of last whorl covered with fine spiral lines like those on the spire; outer lip in front of the wing slightly sinuous."
