Bivalvia
 Arcida - Glycymerididae
"Glycymeris pacificus" = Glycymeris pacifica, Glycymeris shastensis
"Glycymeris pacificus" = Glycymeris pacifica Anderson 1902 clam
I think the occurrence of Glycymeris shastensis here is a typo of a list early in the paper. The later text indicates G. pacfiicus here, and G. shastensis at CAS 27830
Glycymeris shastensis Anderson 1958 clam
