Genus 96. 0D0NT0SCI0N Gill. 
This genus differs from Larimus mainly in the presence of canines, and may be described as a 
Larimus armed with canine teeth. It also approaches closely to Bairdiella, from which it differs in 
lacking the plectroid spine on the preopercle and also in the dentition, the group Elattarclius lying 
between the two, as does also the closely related group Corvula.
