  Four

  223

  were 
  

   obtained

  and 
  P.

  It 
  is 
  readily 
  distin- 
  

   guished 
  from 
  the

  the

  dorsal 
  fin 
  (30-33 
  

   instead 
  of 
  23-26), 
  from 
  the 
  second 
  by 
  the 
  lower 
  number 
  of 
  

   these 
  scales 
  and 
  by 
  the 
  absence 
  of 
  a

   muscular
