Genus Neoplatycephaltjs, Casteln. 

 Form of Platycephalus, but having the villiform teeth very 

 numerous, and interspersed with sharp canine teeth on both jaws 

 and on the palatines. 



If this genus be considered necessary, it will comprise P. 

 einereus, Gunth., and P. Castelnaui, mihi, and probably others 

 now placed in the genus Platycephalus.
