Species / Anchura Raritanensis


Original description of Anchura raritanensis by Richards, 1943, p. 27:

  • "Shell of medium size, spire elongate conical; eight whorls, moderately convex; suture deeply impressed. Protoconch not preserved. Prominent ribs on each whorl, more conspicuous on the penultimate and antepenultimate. Because of the lack of a perfect specimen, it is impossible to determine the number of ribs. On the penultimate whorl they are approximately 2 mm apart. A fair trace of spiral lines can be seen on the body whorl. The outer lip was apparently greatly expanded to form a wing-like structure, characteristic for the genus. Most of the outer lip has been broken away; however notches where the lip was attached to the shell can plainly be seen on the left side of the shell."
