  Guenther, 
  Cat. 
  Fishes, 
  YI, 
  pages 
  167-8, 
  has 
  summed 
  up 
  

   the 
  differences, 
  and 
  all 
  that 
  can 
  be 
  given 
  scientifically, 
  when 
  

   he 
  says, 
  already 
  quoted, 
  "scarcely 
  distinct 
  from 
  0. 
  epeiianus, 
  

   but 
  with 
  a 
  little 
  smaller 
  scales 
  ; 
  the 
  number 
  of 
  transverse 
  

   series 
  above 
  the 
  lateral 
  line 
  being 
  sixty-six. 
  The 
  posterior 
  

   mandibular 
  teeth 
  not 
  larger 
  than 
  the 
  anterior 
  ones."' 
  He 
  

   makes 
  the 
  number 
  of 
  transverse 
  series 
  in 
  the 
  European 
  Smelt 
  

   60-62, 
  and 
  says 
  that 
  the 
  posterior 
  mandibular 
  teeth 
  are 
  

   larger 
  than 
  the 
  anterior 
  ones. 
  I 
  have 
  had 
  an 
  opportunity 
  

   of 
  examining 
  six 
  specimens 
  of 
  Smelts 
  from 
  the 
  Liverpool 
  

   Free 
  Museum, 
  genuine 
  0. 
  eperlani 
  ; 
  and 
  also 
  Smelts 
  from 
  

   all 
  along 
  the 
  Eastern 
  Coast 
  of 
  the 
  United 
  States. 
  

  

  I 
  find 
  that 
  in 
  specimens 
  of 
  equal 
  size 
  of 
  the 
  two 
  forms, 
  the 
  

   scales 
  from 
  the 
  same 
  positions 
  upon 
  the 
  body 
  are 
  either 
  of 
  the 
  

   same 
  shape 
  and 
  size, 
  or 
  a 
  trifle 
  larger 
  in 
  the 
  American 
  jish. 
  

   The 
  teeth 
  are 
  identical, 
  and 
  in 
  both 
  fish 
  the 
  posterior 
  man- 
  

   dihular 
  teeth 
  are 
  scattered, 
  and 
  larger 
  than 
  the 
  anterior 
  ones. 
  

  

  The 
  transverse 
  series 
  I 
  find 
  to 
  be 
  as 
  follows, 
  in 
  specimens 
  

   from 
  different 
  parts 
  of 
  our 
  coast, 
  and 
  in 
  those 
  from 
  Liver- 
  

   pool 
  :
