Genus Type & Synonym 



Mactra M. gigantea. § Invalid 



^gigantea was not included in Linne's genus 

 when founded. Lk. Prod. 85 and Syst. 121 

 cite M. stultorum which selected by Fleming 

 must be taken as type. 



298 25 CrassatcUa 



299 26 C. Kingicola. § Invalid. 



§Not one of the species named when the genus 

 was founded. 



Genus first established by Lamarck in 1799 

 (Prod. 85) genotype Mactra cygnea, Chemn., 

 which is a Mactra. Name utilized again in 

 1801 (Lk. Syst. 119) for C. gihha, Chemn. 

 and another fossil species, while in 1818 the 

 specific name was changed to tiimida; in both 

 cases Venus ponderosa is cited as synonym 

 and this was selected by Gray in 1847 ^^ type. 

 The Crassatella of 1801 and 1818 being pre- 

 occupied by the CrassatcUa of 1799 the ge- 

 neric name Cras satellites of Kriiger, 1823, has 

 been substituted, type Crassatella sinuata, 

 Lmk. (Teste Harris, 1897.) 

 [Paphia created 1799 (Lk. Prod. 85) without 

 type, but for which two species were cited 

 in Lk. Syst. 120, was sunk in the Histoire in 

 species 5 and 7 of Crassatella.] 

 299 26 Erycina E. cardioides. §Invalid. 



§Sole species in the Histoire, but not one of 

 those when the genus was founded. Gray, 

 1847, selected E. trigona and this must be 

 accepted. 



299 26 Ungulina 



300 27 [2] U. transversa 



§Lamarck thought this might be only a variety 

 of ohlonga, which is generally considered to 

 be the type, and it is the form figured in Bosc 

 where Daudin described the senus.
