Remarks

Original Description (from Mansfield, 1930, p. 86):

"Eupleura caudata leonensis closely resembles both Eupleura caudata sulcidentata Dall and E. caudata brevispira, new subspecies. It differs from the former in having more tabulated whorls and fewer and weaker spiral lines on the body whorl. E. caudata brevispira has a less acute spire. In other features the two Miocene subspecies closely agree.

The shell is rather large and consists of about seven whorls.

Type (U. S. N. M. Cat. No. 370197) measures: Altitude, 36 mm.; greatest diameter, 20 mm.

Occurrence: Upper Miocene: Harveys Creek, half a mile above abandoned mill, Leon County, Fla., type and only locality. The type was collected by the Florida State Geological Survey."
