Type specimens of Pectinidae (Mollusca: Bivalvia) described by Linnaeus (1758–1771)

Linnaeus listed and described (as Ostrea species) 20 recent pectinid species in the 10th edition of his Systema Naturae and one pectinid species in his Mantissa. These are now placed in 17 genera of the family Pectinidae. Nine species are cited to Museum Ludovicae Ulricae. Ten primary types are present in the Linnéan Society of London, and the same number in die Zoological Museum of die Uppsala University. Two lectotypes were designated recendy by Smith and Waller; 18 lectotypes and one neotype are selected herein. Nine of the species are type species of currently accepted pectinid genera. Seven new type localities are also designated for species which had unknown or erroneous type localities, and six are more restricted. Potential type material of eight species is also traced in the Gualtieri collection of the Museo di Storia Naturale e del Territorio at Certosi di Calci (Italy).
