Coccopigya sp.

Fig. 9C .

Material.— One specimen ( NRM Mo187034) from Cerro la Salina block 6, upper Oligocene, Talara Basin, Peru .

Description.—Elongate-oval, moderately tall limpet shell with apex at about anterior third of shell; sculpture of indistinct but broad radial ribs, about 30 on each side of shell, more densely spaced at anterior end; fine radial growth increments visible.

Remarks.—With its narrow shell and anteriorly displaced apex, this specimen is remarkably similar to the early or middle Miocene Coccopigya compunctum ( Marwick, 1931) from New Zealand ( Marwick 1931; Marshall 1986).
