the tongue; lower jaw longest; a well-developed supplemental maxlUary bone; gill- 

 rakers long and strong, about ten of them on the anterior arch longer than the rest, and 

 armed with teeth ; opercnlnm without flap, ending in two flat points. 



The synonymy of this genns requires no special remark. The name Amilo- 

 plites was first suggested by Kafinesqne as a sub-genus of his Lepomis (1820, 

 micropterus) but without characterization of any importance. In 1854, the genus was 

 first established and characterized by Prof. Agassiz who retained Bafinesque's name as 

 by the laws of nomenclature he was obliged to do. But one species of AmblopUtes is 

 certainly known.
