Mursia simplex ( Remy, 1960) n. comb. ( Fig. 1E )

Cenomanocarcinus simplex Remy, 1960: 56 , text-fig. 1, fig. 3 of the plate.

TYPE MATERIAL. — Holotype (dorsal carapace) by monotypy ( MNHN R03849, coll. Tessier).

TYPE LOCALITY. — Probable Eocene rocks on the seacliff below Kraïebouen hill, near Fresco, 5.03°N, 5.31°W, Ivory Coast, Africa ( Remy 1960).

DISCUSSION

One other Eocene species of Mursia is known, from Pacific coastal North America ( Schweitzer & Feldmann 2000). Th e records for the genus span tropical and temperate localities, so the occurrence of an Eocene species in West Africa extends the geographic range of the genus but not the geologic or ecological range. Th e North American occurrence is late Eocene in age; it is not possible at this time to determine whether the African occurrence is older as it is simply reported as probably Eocene.
