Order L. CYCLOGANOIDEA.

 family AMIID/E. (/UKAOC, circle; Ganoidea; also called HALECOMORPHI, 

 tafocoviorpfaM, formed like a shad; halec, in allusion to the resemblance 

 between this group of GANOIDS and the ISOSPONDYLI. It is probable that 

 the ancestors of the ISOSPONDYLI are to be found among forms allied to 

 the existing HALECOMORPHI.)
