Descrição original:
(Pilsbry, 1904): “Shell larger, with much more widely open umbilicus; columella distinctly trilamellate; scallops of the columellar lamella bent downward somewhat. Sculpture as in typical elatior. Length 44, diam. above aperture 9 mm., whorls 19 ; length 38, diam. 8.6 mm., whorls 16 2/3.
This variety approaches Megaspira ruschenbergiana in size and in its open umbilical chink, but differs in internal structure. The teeth of one of our specimens were figured under the name Megaspira elata Gould, in Proc. Acad. Nat. Sci. Phila., 1898, pp. 283, 285, pi. 17, f. 1.”
