  I 
  have 
  examined 
  specimens 
  of 
  Menidia 
  menidia 
  (Linnaeus) 
  from 
  

   Charleston, 
  S. 
  C, 
  the 
  type 
  locality 
  of 
  the 
  genotype, 
  as 
  well 
  as 
  numerous 
  

   specimens 
  from 
  the 
  Atlantic 
  coast 
  in 
  the 
  National 
  collections, 
  the 
  lots 
  

   too 
  numerous 
  to 
  make 
  it 
  practical 
  to 
  list 
  the 
  catalog 
  numbers. 
  Also 
  I 
  

   have 
  examined 
  numerous 
  lots 
  of 
  Menidia 
  heryllina. 
  and 
  M. 
  peninsulae. 
  

   The 
  latter 
  species 
  appears 
  to 
  have 
  fewer 
  caudal 
  vertebrae; 
  in 
  10 
  counts 
  

   1 
  found 
  a 
  range 
  of 
  17 
  to 
  19 
  + 
  19 
  to 
  22, 
  whereas 
  in 
  M. 
  menidia 
  in 
  4 
  counts 
  

   the 
  range 
  was 
  17 
  to 
  19 
  + 
  24 
  to 
  27 
  vertebrae. 
  No 
  doubt 
  the 
  number 
  

   of 
  caudal 
  vertebrae 
  in 
  the 
  species 
  of 
  Me^iidia 
  would 
  overlap 
  if 
  numer- 
  

   ous 
  additional 
  counts 
  were 
  made 
  throughout 
  the 
  range 
  of 
  these 
  

   species. 
  

  

  I 
  have 
  examined 
  the

  The

  is 
  based
