  I 
  concur 
  in 
  the 
  opinion 
  of 
  Jordan 
  and 
  Hubbs 
  that 
  the 
  generic 
  name 
  

   Membras 
  Bonaparte 
  is 
  valid 
  because 
  there 
  was 
  a 
  definite 
  indication 
  on 
  

   the 
  part 
  of 
  Bonaparte 
  that 
  he 
  was 
  taking 
  the 
  germ 
  of 
  his 
  chissification 
  

   from 
  that 
  of 
  Cuvier 
  and 
  Valenciennes. 
  Since 
  Cuvier 
  and 
  Valenciennes 
  

   list 
  a 
  species 
  {Atherina 
  martinica) 
  for 
  one 
  of 
  the 
  groups 
  distinguished 
  

   by 
  them 
  and 
  since 
  later 
  a 
  generic 
  name 
  (see 
  p. 
  16) 
  was 
  assigned 
  by 
  

   Bonaparte, 
  there 
  remains 
  no 
  doubt 
  about 
  the 
  validity 
  of 
  the 
  genus 
  

   Memhras 
  Bonaparte. 
  

  

  The 
  nature 
  of 
  the 
  species 
  described 
  by 
  Cuvier 
  and 
  Valenciennes 
  as 
  

   Atherina 
  martinica 
  has 
  never 
  been 
  exactly 
  clear, 
  even 
  though 
  Jordan 
  

   once 
  redescribed 
  it. 
  In 
  an 
  attempt 
  to 
  clear 
  this 
  matter 
  up 
  I 
  wrote 
  to 
  

   Dr. 
  L. 
  Bertin, 
  of 
  the 
  Museum 
  National 
  d'Histoire 
  Naturelle 
  of 
  Paris, 
  

   and 
  he 
  examined 
  the 
  three 
  types, 
  furnishing 
  the 
  following 
  informa- 
  

   tion, 
  for 
  which 
  I 
  convey 
  my 
  sincere 
  thanks 
  to 
  him 
  : 
  

  

  The 
  three 
  types 
  of 
  Atherina 
  martinica 
  measure 
  68 
  (58) 
  ,99 
  (85) 
  , 
  and 
  

   100 
  (86) 
  mm. 
  in 
  length, 
  with 
  standard 
  length 
  given 
  in 
  parentheses. 
  

   The 
  body 
  cavity 
  does 
  not 
  extend 
  quite 
  to 
  the 
  anal-fin 
  origin 
  ; 
  ascending 
  

  

  * 
  The 
  subspecies 
  of 
  this 
  genus 
  have 
  not 
  been 
  clearly 
  worked 
  out, 
  although 
  Memhras 
  

   martinica 
  lacinata 
  is 
  indicated 
  by 
  Jordan 
  and 
  Hubbs 
  as 
  ranging 
  from 
  New 
  Yorli 
  to 
  Florida 
  

   and 
  MemWas 
  martinica 
  vagrans 
  along 
  the 
  Gulf 
  coast. 
  If 
  the 
  form 
  in 
  the 
  West 
  Indies 
  

   region 
  is 
  subspecifically 
  distinct 
  it 
  should 
  have 
  the 
  name 
  Membras 
  martinica 
  martinica.
