  Bceostoma 
  should 
  probably 
  be 
  regarded 
  as 
  a 
  subgenus 
  of 
  Achirus 
  rather 
  than 
  as 
  a 
  

   distinct 
  genus. 
  Among 
  the 
  numerous 
  species, 
  the 
  pectoral 
  of 
  the 
  right 
  side 
  is 
  found 
  

   in 
  every 
  degree 
  of 
  development. 
  In 
  some 
  species, 
  a 
  small 
  pectoral 
  is 
  found 
  on 
  the 
  

   left 
  side 
  in 
  some 
  specimens, 
  while 
  it 
  is 
  wanting 
  in 
  others. 
  Still 
  other 
  species 
  have 
  

   also 
  two 
  pectorals 
  developed.

  s 
  The 
  name 
  Pleuronectes 
  achirus 
  L. 
  (Achirus 
  fasciatus 
  Lac.) 
  was 
  based 
  on 
  specimens 
  

   from 
  Surinam 
  ; 
  the 
  name 
  Pleuronectes 
  lineatus 
  on 
  the 
  figures 
  of 
  Brown 
  and 
  Sloane 
  of 
  

   fishes 
  from 
  Jamaica. 
  If, 
  therefore, 
  the 
  West 
  Indian 
  form 
  is 
  considered 
  distinct 
  from 
  

   the 
  northern 
  one, 
  the 
  former 
  must 
  be 
  Achirus 
  achirus 
  or 
  Achirus 
  lineatus, 
  and 
  the 
  latter 
  

   must 
  take 
  Mitchill's 
  name, 
  il 
  mollis." 
  If 
  considered 
  as 
  varieties 
  of 
  one 
  species, 
  the 
  

   West 
  Indian 
  form 
  has 
  the 
  prior 
  names.
