Pecten jamesoni Forbes in J. Smith, 1839
SMITH, J. 1839. On the last changes in the relative levels of the land and sea in the British Islands. Memoirs of the Wernerian Natural History Society, 8: 49-113. [p. 106, pl. 2, fig. 1]
«1. PECTEN JAMESONI. N. S.— Smith.
P. testa sub-aequivalvi, suborbiculari, longitudinaliter undulato-plicata, striata, plicis 4-5, auriculis inaequalibus. Lon. ¾ un. Lat. ¾.
Allied to the Pecten polymorphus of Bronn (Phillippi, p. 79, tab. v. figs. 18, 21), but differs in several respects, especially in the inequality of the auricles. The longitudinal striae vary much in coarseness; the upper valve is somewhat larger than the lower; the auricles are ribbed and striated by lines of growth; the longitudinal ribs or folds vary much in convexity, and are sometimes acutely carinated. The colour is white, with a tinge of red, especially near the beaks. Very distinct from any recorded British Pecten.— F. Dredged at Bute by Mr Smith.» EDWARD FORBES, 1839
