Extra details from original publication
This species differs from G. aequilateralis Brady) (1884, Rep. Voy. Challenger. Zoology xol. 9, p. 605, pl. 80. tigs. 18-21) in being more evolute; in that species, the whorls barely touch. The large aperture, more coarsely perforate test, and more appressed chambers distinguish this species from G. voluta White (1928, J. Paleont.. vol. 2. p. 197).
