Conch., III. 67 (1867). A species of the Cumberland Subregion, found in Tennessee at Clarkeville and Nashville and in Franklin County, in Kentucky in Henry County. P. fastigans is larger than Troostiana, Hazardij and DorfeuilUana; it is most nearly allied to the first, and though it is connected with the second, is wholly distinct from the last. The parietal tooth is more rectangular than that of Troostiaim, in which it is slightly emarginate near the tip, but much more so in Hazardi, while the parietal tooth in DorfeuilUana is rather quadrate.
