Referred Specimens—Hypotype (of Smith, 1975) (Figs. 7A–C) CASG 61666.06 [ex LSJU 10235 of Gisortia sp. cf. G. clarki View in CoL ], length 39 mm length, width 25 mm width, height 22 mm, CASG Locality 61666 [ex LSJU Locality 2073, = UCMP Locality A-9717], Tumey Hills, Fresno County, middle California.

Occurrence— Basal Lodo Formation, Paleocene (Thanetian Stage).

Remarks— This medium-size gastropod is represent- ed by a single specimen, which is too poorly preserved to be positively assigned to a genus or species. The speci- men is an internal mold, is missing its right posterior end, and the aperture is filled with matrix. The general shape of this specimen resembles superficially the specimens of Protocypraea ? sp. 2 also from the Lodo Formation.
