* The generic name Bucardia, being pre-Linnaean, must give way to Poli's 

 name, that being the first one given to the genus under the binomial system. 



t I place this name as a synonym of V. Conradi, only from the evidence of 

 the figure given in the Synopsis. The Academy of Natural Sciences has all the 

 known types of the Synopsis, and the only specimen in the Academy's museum 

 resembling the figure is an undoubted cast of that species. Should it prove a 

 distinct species, it is exceedingly rare, since I have never met with it among 

 thousands of cretaceous fossils.
