Pecten catillifornis Conrad, 1855
CONRAD, T. A. 1855. Report of Mr. T. A. Conrad on the fossil shells collected in California by W.P. Blake, geologist of the expedition, under the command of Lieutenant R.S. Williamson, United States Topographical Engeneers, 1853. In: William P. Blake (1855): Description of the fossils and shells collected in California by William P. Blake. Appendix to the preliminary geological report. Washington, 1855: 5-21. [p. 20]
«61. P. CATILLIFORNIS, Conrad, pl. viii, fig. 83. Orbicular planoconvex, with radiating stride and distinct rounded ribs; ears equal.
Locality.— Ocoya creek.— W. P. Blake. This large Pecten has such a general resemblance to P. Madisonius, Say, of the Virginia Miocene, that I have no doubt it existed at the same period, or at least after the Eocene. There is none such now living on the coast of California, and none in the Eocene, of this group of large Pectens, which occur almost everywhere in the Miocene deposits of the Atlantic slope.» TIMOTHY ABBOT CONRAD, 1855
