Original Description (from Dall, 1903, p. 1429-1430):
“Oligocene of the Chipola horizon on the Chipola River and at Alum Bluff on the Chattahoochee River, Calhoun County, Florida; Burns and Dall.
Shell solid, robust, obliquely oblong, the beaks full, prominent, prosogyrate, and nearly anterior; anterior side short, bluntly rounded, posterior side longer, compressed, roundly subtruncate behind; sculpture of about nineteen radial ribs, of which the posterior five or six are smaller and less elevated than the others; anterior ribs stout, sometimes with a thread or terrace laterally, the summit articulated rather sparsely with small, squarish, transverse nodules, which have a tendency to become obsolete behind and below; interspaces narrower than or subequal to the ribs, partially channelled; lunule extremely small and deeply incised; hinge normal; the anterior cardinal pustular, the interior margins with shallow flutings. Length 47, height 38, diameter 36 mm.
A remarkably fine species, abundant in the Chipola beds, and not likely to be confounded with any but the following species.”
