Unfortunately Arnold's name for the well known Lower Pliocene species is preoccupied for a recent one of the Philippines. His remarks upon the relationship of the California species are apparently correct. He stated "This species is quite closely allied to P. healeyi, of which it is probably the precursor. It may be distinguished from the latter by its smaller size, greater convexity, fewer and stronger ribs, more prominent intercalary riblets on the right valve, and relatively much longer hinge line." Pecten lohri is common at many places and has been reported from the Etchegoin, Purisima, Pico, lower Wildcat, and Merced (of Pillar Point), formations of California, all of which are lower Pliocene. It apparently does not occur in the Upper Miocene as originally suggested. This species is named for Dr. Fred von Lohr, topographer who accompanied Mr. W. M. Gabb on an expedition into Lower California.» LEO GEORGE HERTLEIN, 1928
