Conus (Dauciconus)  gravesae (Petuch, 1994)

Description ⁽³⁾: Shell small for genus, stocky, broad across shoulder, with low spire; shoulder sharply-angled, carinated; subsutural areas slightly sloping; body whorl smooth, with numerous very faint spiral threads; aperture narrow throughout; color pattern (when preserved) composed of numerous fine spiral lines.

Holotype: UF66426, Length 29 mm.

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

Remarks: Conus gravesae is most similar to the sympatric C. joelshugari n. sp. (Plate 91, Figure K), but differs in being a larger, broader, and less elongated shell, in lacking a sharp, bladelike shoulder carina, in lacking a projecting, needlelike proto-conch, and in lacking deep spiral sulci around the anterior tip. The new species has only ever been collected in the coral reef facies of the Caloosahatchee deposits along the Miami Canal.

Etymology: Named for Ms. Gypsy Graves, Director of the Graves Museum of Archaeology and Natural History.

Le tre specie Conus griffini, Conus gravesae e Conus harbisoni potrebbero essere sinonimi del Conus daucus ⁽¹⁾, ma Petuch ⁽²⁾ ha evidenziato che l’articolo di Hendricks contiene parecchi errori.
