  at 
  the 
  caudal 
  peduncle 
  and 
  compressed 
  throughout, 
  with 
  the 
  ventral 
  

   edge 
  of 
  the 
  belly 
  of 
  almost 
  paper 
  thinness; 
  premaxillaries, 
  although 
  

   nonprotractile, 
  not 
  dilated 
  posteriorly, 
  thus 
  suggesting 
  relationships 
  

   with 
  the 
  Taeniomembrasinae. 
  

  

  Genus 
  NOTOCHEIRUS

  NotocJieirus 
  Clariv, 
  Copeia, 
  1937, 
  No. 
  2, 
  p. 
  88 
  (genotype: 
  Notocheirus 
  huhbsi 
  

   Clark). 
  

  

  This 
  remarkable 
  genus, 
  based 
  on 
  two 
  specimens 
  from 
  Valparaiso 
  

   Harbor, 
  Chile, 
  is 
  one 
  of 
  the 
  most 
  aberrant 
  of 
  the 
  atherine 
  fishes, 
  related 
  

   to 
  Tropidostethus 
  rhothophilus 
  Ogilby 
  from 
  the 
  Australian 
  region 
  and 
  

   Iso 
  -flos-maris 
  Jordan 
  and 
  Starks 
  from 
  Japan. 
  I 
  have 
  examined 
  the 
  

   paratype 
  of 
  N. 
  hubhsi, 
  and 
  the 
  generic 
  diagnosis 
  is 
  based 
  largely 
  on 
  

   that 
  specimen. 
  Indeed 
  I 
  have 
  gone 
  to 
  great 
  trouble 
  to 
  make 
  a 
  count 
  

   of 
  the 
  vertebrae, 
  which 
  number 
  14 
  + 
  26 
  on 
  the 
  paratype, 
  kindly 
  lent 
  me 
  

   for 
  study 
  by 
  Dr. 
  W. 
  M. 
  Chapman,

  of 
  fishes,
