Kohniconus susankhanae

Kohniconus susankhanae (Petuch, 1994)

Description ⁽³⁾: Shell large for subgenus, elongated, very broad across shoulder, with low pyramidal spire; shoulder sharply-angled, obsoletely carinated; body whorl smooth; polished with 8 wide, shallowly impressed spiral sulci around anterior tip; aper ture narrow throughout; spire whorls ornamented with 2 wide, very low, almost-obsolete spiral cords; col or pattern (when present) composed of 12-14 rows of large, oval dote.

Holotype: UF66998, Length 97 mm.

Type Locality: Caloosahatchee Fauna, from Miami Canal dredging. 12 miles south of Lake Harbor, Palm Beach County.

Remarks: The new Caloosahatchee C. susankhanae is most similar to the older, stratigraphically lower C. presozoni Olsson and Petit, 1964 (Plate 92, Figure A) from the Pine crest Beds, but differs in being a stockier, less elongated shell with a wider shoulder and spire, and in having larger, wider spiral sulci around the anterior tip. Conus susankhanae is the direct ancestor of the living and Bermont C. delessertii Reclus, 1843 (Plate 91, Figure N).

Etymology: Named for Ms. Susan Khan of New Port Richey, Florida.
