I0l6 CLASS PISCES. 



Ancistrodon, founded upon detached teeth from the Chalk of 

 France ; similar teeth also occurring in the Cretaceous of Texas. 

 These teeth are generally regarded as pharyngeal teeth of Teleostei, 

 although it has been suggested that they may prove to be anterior 

 teeth of Pycnodont Ganoids.
