Conus (Leptoconus) ronaldsmithi (Petuch, 1994)

 

Description (2): Shell small for genus, elongated, with moderately-high, pyramidal spire; shoulder sharply-angled, only obsoletely carinated; shell smooth, with body whorl ornamented with num numerous very poorly-developed, almost-obsolete spi-ral cords; anterior tip circled with 6 incised spiral sulci; aperture narrow throughout.

Holotype: UF66429, Length 34 mm.

Type Locality: Caloosahatchee Fauna, from Miami Canal dredging, 20 miles south of Lake Harbor, Palm Beach County.

Remarks: Conus ronaldsmithi is most similar to the younger, stratigraphically-higher C. floridanus Gabb, 1868 from the Bermont, Fort Thompson, and Recent faunas (Plate 92, Figure J), but differs in being a broader, stockier shell with a wider, more pyramidal spire, in having a less-carinated shoulder angle, and in having the faint spiral cord sculpture.

Etymology: Named for Ronald Smith, M.D., F.R.C.P. of Weston, Fort Laud-erdale, Florida.
