Original Description of Rostellaria marginata by Sowerby in Fitton, 1836 , p. 336:

• "Fig. 18 Rostellaria marginata. Turrited, conical, transversely striated ribs, eight or ten upon each whorl, short and obtuse, last whorl keeled without ribs. Named from a ridge or narrow band upon the upper edge of each whorl, which is more or less conspicuous in every specimen and assists in distinguishing the species from Rostellaria Parkinsoni See PI XVIII fig 24."

Stratum typicum: Gault, Albian, lower Cretaceous

Locus typicus: Copt Point, Folkestone, Kent County, South East Region, England

Vega et al. 2006, p. 327:

• Perissoptera marginata (Sowerby, 1829) (Gardner, 1857, p. 198, pi. 6, figs. 1–3) from Gault of Folkestone, Paris Basin, Mediterranean Basin, and Switzerland is composed of eight convex angulated whorls, which are closely covered with spiral striae, the whorls ornamented by short elongated ribs, which are nodose and tubercular on the lower, but thin and linear on the upper whorls. On the last whorl there are two more or less distinct rows of tubercular nodes; the uppermost row being the more important, is continued in the form of a tuberculated ridge on the wing process. The wing is large, broad and quadrate. The Mexican specimens have no nodose and tubercular ribs and have more whorls and are smaller shells.
