  ) 
  

  

  This 
  genus 
  is 
  very 
  close 
  to 
  Paralichthys, 
  differing 
  chiefly 
  in 
  the 
  dentition, 
  the 
  teeth 
  

   . 
  eing 
  small 
  and 
  uniform 
  in 
  size, 
  arranged 
  in 
  a 
  single 
  row. 
  The 
  scales 
  are 
  ctenoid, 
  

   'j 
  he 
  eyes 
  are 
  unusually 
  large 
  in 
  the 
  single 
  known 
  species, 
  which 
  bears 
  a 
  remarkable 
  

   rusemblance 
  to 
  Hippoglossoides 
  jordani. 
  The 
  lateral 
  line 
  is 
  however 
  anteriorly 
  arched 
  

   in 
  Hippoglossina, 
  but 
  straight 
  in 
  the 
  latter 
  species.

  diminutive 
  of
