SPECIES OF THE SYSTEMA. 
Carvdtunr serrate, 
The Cardium levigatum (Wood, Gen. Conch. pl. 54, f. 3) of 
Lamarck is marked for this species in the Linnean cabinet, a 
circumstance which confirms the surmise of Gronovius, and 
the conclusion that M. Deshayes had arrived at from his care- 
ful study of the ‘Museum Ulvrice.’ 
““Nates regulares” is followed by “intus incarnate” in the 
revised copy of the ‘Systema Nature.’ 
Cardin edule. 
The Cardiwm edule (Wood, Gen. Conch. pl. 55, f. 4) of 
authors is marked for this species in the Linnean cabinet. 
Cardtunr rustic. 
“ List. t. 829” is added by our author in his own copy of the 
‘Systema.’ This figure, as well as Gualtier’s, the “ Concha 
striata prima” of Rondelet, and the four referred to in Regen- 
fuss, all represent the Cardiwm tuberculatum of British writers. 
The marked specimen (C. rusticum, Reeve, Conch. Icon. vol. ii. 
pl. 8, f. 16) confirms the inference to be drawn from the 
synonymy. ‘The reference to Rumphius, whose engraving 
exhibits an Arca with somewhat the look of granosa, was erro- 
neous. 
Carvdtwm pectiwateum. 
Our author has not indicated his possession of this species, 
which, thanks to the ample details of the ‘Museum Ulrice,’ has 
been satisfactorily recognised by Spengler, Bruguiére, Dillwyn, 
Deshayes and Reeve, in a shell (Chemn. Conch. Cab. vol. vi.
