 and distal radials separate; Stay — separate bony element posterior to ultimate pterygiophore in D and A; Predorsal formulae — based on Ahlstrom 

 et al, (1976); P— pterygiophore with no supernumerary spines or soft rays; H — hypurals; E— epurals; U — uroneurals; Ah— autogenous haemal 

 spines; pH — parhypural; UR — urostyle; Proc spur— procurrent spur (see Johnson, 1975); PU3 cart- radial cartilage anterior to neural and haemal 

 spines of third preural centrum; BR — branchiostegals; lAC— interarcual cartilage; Cy— cycloid; Ct— ctenoid, ctenii free from posterior margin; 

 Ct— ctenoid, ctenii continuous with posterior margin; and br— branched caudal fin rays. With the exception of (SS), parentheses enclose features
