Pecten panamensis Dall, 1898
DALL, W. H. 1898. Contributions to the Tertiary fauna of Florida. Silex Beds of Tampa and the Pliocene Beds of the Caloosahatchie River. Part IV. Transactions of the Wagner Free Institute of Science of Philadelphia, 3 (4): i-viii, 571-947. [p. 696]
«Pecten panamensis Dall, which has in most respects an unusually close resemblance to P. plica, differs by having the cardinal laminae obsolete and in the presence of a byssal sinus and ctenolium. In fact, the interchange of characters is so multifarious that one must, to be consistent, either propose a genus for every two or three species of Pecten or include all the species in one generic group. Locard, who adopts the former method, has proposed the name Felipes for a closely allied group with P. pesfelis L. as the type; and Bucquoy, Dautzenberg, and Dollfus (1889) propose Peplum, with P. clavatus Poli as type, which would include such species as P. panamensis; and Sacco adds Flexopecten (1897) for P. flexuosus Poli, which differs by having larger ears.»
