  as 
  a 
  synonym. 
  The 
  teeth 
  of 
  the 
  lower 
  jaw 
  at 
  the 
  front 
  have 
  uneven 
  

   edges 
  but 
  are 
  not 
  bifid 
  or 
  trifid 
  as 
  in 
  certain 
  other 
  genera. 
  I 
  count 
  

   dorsal 
  rays 
  as 
  12, 
  anal 
  as 
  9, 
  and 
  pectoral 
  23.
