«SWIFTOPECTEN Hertlein
Swiftopecten Hertlein, Proc. Calif. Acad. Sci., Ser. 4, Vol. 21, no. 25, 1935, p. 319. Type: Pecten swiftii Bernardi, Journ. de Conchyl.. Vol. 7, 1858, p. 90, pl. 1, fig. 1; pl. 2, fig. 1. "Hab. la baie Nicholas, dans la Manche de Tartarie."
This section was proposed to include the well known Pecten swiftii group, Pliocene to Recent in Japan, and P. parmeleei and related forms in the Pliocene of California.
If Matsumoto¹ is correct in supposing that P. natoriensis is the ancestral form of P. cosibensis Yokoyama, then this group is apparently not closely related to the P. pes-felis group which occurs from Miocene to Recent in the Mediterranean region, and which belongs to the section Manupecten Monterosato.² That sectional name appears to antedate Felipes (Locard) Carus³ by a few months. Mr. Thomas Cowles, formerly librarian of the California Academy of Sciences, has kindly taken the trouble to write Mr. A. C. Townsend, librarian of the British Museum, regarding the date of issue of this work. Mr. Townsend in a letter dated September 10, 1932, stated ... "I find that the date on the original wrapper, which we have preserved, of Vol. 2, Pars 1, Brachiostoma. Mollusca, pp. 1-272, is 1889 [this pagination is written in in manuscript on the wrapper]. A stamp at the top of the wrapper states that the part was received in the Library of this Museum on the 19th December, 1880, so it was probably issued either at the end of November or early in December." "Pecten pes felis Lam." occurs in the faunal list followed by parentheses containing the names of species which were apparently considered to be synonyms. These were " (Ostrea pes-felis L., P. elongatus Born, O. corallina Poli, P. Bornii Payr.)," "(Var. alipus De Greg., Sicilia)."—Dall, Trans. "Wagner Free Inst. Sci., Vol. 3, pt. 4, 1898, p. 696-697. Felipes cited "with P. pesfelis L. as the type." Pecten swifti has been referred to the section Pallium by some authors, but it has been pointed out by Cox and others that Pallium Schumacher with the type Pecten plica Linnaeus, can not be used due to the earlier Pallium Schröter (Archiv. für Zoologie und Zootomie, Bd. 3, 1802, p. 135). If Pallium of Martini is not accepted, then Decadopecten Rüppell in Sowerby,⁴ can be used for the section which has Pecten plica as type.» ¹ Sci. Rept. Tohoku Imp. Univ.

Species included in original list: P. pes-felis, P. radula, P. tigris, P. fulvicostatus.—Monterosato, Journ. de Conchyl., Vol. 47, no. 3, 1899, p. 190. "Type : P. pes-felis, auct." ³ Prod. Faunae Mediterr., Bd. 2, 1889, p. 71. ⁴ Decadopecten Rüppell in G. B. Sowerby, Conch. Manual, 1839, pp. 37, 78, 121, fig. 172. Type by monotypy, Pecten plica Linnaeus. This was spelled Decatopecten in the original, but in later editions of Sowerby's manual it was spelled Decadopecten. Sherborn indicated that the original spelling was "[err. typ. pro Decado-]." Dentipecten Rüppell in J. E. Gray (Proc. Zool. Soc. London, 1847, p. 200. Type by monotypy, Pecten plica Linnaeus) is an exact synonym of Decadopecten. HERTLEIN, L. G. 1936.
