Genus Type & Synonym 



C. hisoria (Venus lusoria, Chemn.) 

 §Lamarck's original name of Meretrix (Prod. 

 85) stands for this genus, with genotype 

 Venus meretrix, Lin. He changed the specific 

 name in Syst. 122 to labiosa. The type is 

 therefore Meretrix meretrix (Lin.). 

 [Non Cytherea, Bolten, 1798, for which Dall 

 gives as type Venus piierpera, Lin.] 



313 40 Venus 



314 41 V. piierpera (Idem. Linn.) 



§Not one of the species inchided in Linne's 

 genus. Gray, 1847, selected V. verrucosa, Lin. 



314 41 Venericardia V. planicosta. §Stet. 



§Genus founded by Lamarck (Syst. 123) for 

 V. imbricata and V. planicosta. 



315 42 Cardiuui C. costatum (Idem. Linn.) §Stet. 



§Lk. Prod. 86 cites C. aculeatmn, Lin., but in 

 Syst. 119 transferred to C. costatum, Linne's 

 first species. 



316 43 Cardita C. sulcata (Chama antiquata. 



Linn.) Stet. 

 §Genus founded by Bruguiere in 1792 with 13 

 species. Lk. Prod. 86 cites Chama calyculata, 

 Lin., but in Syst. 118 changed to C. I'ariegata, 

 Br., which in the Hist, is sunk in C. calyculata 

 (Lin.). 



316 43 Cypricardia C. Guinaica {CJiauia ohlonga, 



Linn.) 

 §Lamarck's name being a synonym the type 

 name should read C. ohlonga (Lin.) 

 [Genus preceded by Libitina, Schumacher, 

 1817.] 



317 44 Hiatella H. arctica (Mya arctica. Linn.) 



§Sole species quoted by Lamarck, who admits 

 he was unacquainted with the genus, and cer- 

 tainly not one of Daudin's indeterminable 

 two. Lamarck's synonymy cites both Mya 

 arctica, Lin., and Solen rninutus, Lin. The 

 latter was selected by Gray, 1847, ^s type for 

 Daudin's jjenus.
