  that 
  these

  belong

  I 
  have 
  examined 
  sev- 
  

   eral 
  lots 
  from 
  the 
  Hawaiian 
  and 
  Philippine 
  Islands 
  and 
  one 
  lot

   off 
  Mauritius.

  The 
  generic 
  diagnosis 
  was 
  based 
  on 
  numerous 
  specimens 
  of 
  A. 
  stipes 
  

   from 
  the 
  western 
  North 
  Atlantic, 
  the 
  collection 
  containing 
  so 
  many 
  

   lots 
  that 
  it 
  is 
  not 
  practical

  (geno- 
  

   type:

  This 
  aberrant 
  genus 
  of 
  silversides 
  is 
  placed 
  in 
  a 
  separate 
  subfamily 
  

   because 
  Atherion 
  appears 
  to 
  be 
  intermediate 
  between 
  the 
  Taeniomem- 
  

   brasinae 
  and 
  the 
  Menidiinae. 
  

  

  Atherion 
  combines 
  the 
  concave 
  premaxillary, 
  shagreenlike 
  denti- 
  

   cles 
  on 
  outer 
  surface 
  of 
  premaxillary, 
  broad-based 
  and 
  short 
  ascend- 
  

   ing 
  premaxillary 
  process, 
  and 
  broadened 
  end 
  of 
  premaxillary, 
  with 
  

   the 
  body 
  cavity 
  ending 
  bluntly 
  in 
  front 
  of 
  the 
  anal 
  origin 
  and 
  not 
  

   entering 
  the 
  haemal 
  arches.

  No. 
  49812, 
  from 
  Japan, 
  

   were 
  examined, 
  as 
  well 
  as 
  numerous 
  other 
  specimens 
  of 
  the 
  same 
  genus 
  

   from 
  Guam 
  and 
  Bikini 
  Atoll. 
  The 
  paratypes 
  are 
  in 
  a 
  bad 
  state 
  of 
  pres- 
  

   ervation, 
  having 
  been 
  dried. 
  Two 
  other 
  species 
  are 
  A. 
  maccullocM

  Hubbs 
  and 
  Atherina

  this 
  genus. 
  

  

  Tropidostethinae, 
  new 
  subfamily 
  

  

  This 
  subfamily 
  contains, 
  at 
  the 
  present 
  time, 
  three 
  genera 
  character- 
  

   ized 
  by 
  their 
  greatly 
  compressed 
  bodies, 
  with 
  the 
  head 
  short 
  and 
  

   truncate 
  posteriorly; 
  the 
  air 
  bladder 
  not 
  extending 
  into 
  the 
  haemal 
  

   arches 
  as 
  in 
  the 
  Atherininae 
  ; 
  the 
  greatest 
  depth 
  of 
  the 
  body 
  occurring 
  

   near 
  the 
  rear 
  of 
  the 
  head 
  and 
  then 
  the 
  body 
  tapering 
  to 
  the 
  least 
  depth
