- Strombus jeffersonia Van Hyning, 1945
synonym of Lobatus costatus
Original Description of Strombus jeffersonia by Van Hyning, 1945, p. 95:
- Except for the two more prominent tubercules, jeffersonia has none of the specific characters of raninus, as the natural size photographs here shown will bear out, jeffersonia is a little larger than raninus which is 112 mm for jeffersonia and 110 mm for raninus. Our specimen of jeffersonia, however, do not have the protoconch and early whorl. The color alone of jeffersonia will at once distinguish it from raninus, the former pink and the latter light gray exteriors, and jeffersonia with white, and raninus with pink interiors. The axial sculpture of jeffersonia does not show any of the tubercular bands below the periphery that exists with raninus. The heavy folds or lamella on the upper and inside corner of raninus do not occur with jeffersonia."
