1 This selection of the chief family-diversities of the vast, acanthopterotts order is 

 designed, like the families cited under other orders, merely to exemplify it by familial- 

 fishes with vernacular names. For the characters and affinities of all the present 

 known acanthopterous ftimilie^, see Dr. Gun tiler's excellent woik, CLXXIV.,
