PANDORA Bruguière, 1797

Type species —By subsequent designation ( Children, 1823), Pandora rostrata Lamarck, 1818 = Solen inequivalvis Linnaeus, 1758 ). Holocene, Mediterranean.

The controversy over the appropriate generic name, type species, type designation, and history of interpretations of the zoological code are discussed in detail by Boss and Merrill (1965).

In the northeastern Pacific, pandorids first appear in the late Eocene in the Eocene–Oligocene turnover faunas marking global cooling and onset of subduction and forearc volcanism on the Cascadia margin. There are four previously-described Paleogene species from the eastern Pacific margin. They are compared and distinguished by Hickman (1969, p. 72) in the description of Pandora laevis Hickman, 1969 from the Eugene Formation. The new Keasey species is distinguished from all four by the far anterior placement of the beaks and long, shallowlyarcuate posterio-dorsal margin. This is the lowest stratigraphic pandorid appearance in the Pacific Northwest, followed by P. washingtonensis Weaver, 1916 , P. laevis , and P. vanwinkleae Tegland, 1933 , although there is no implication that they represent an evolutionary series.

Stratigraphic range —Eocene to Holocene.
