  Description 
  of 
  the 
  Selene 
  Argentea 
  of 
  Lacipede, 
  

  

  how 
  strongly 
  the 
  characters 
  are 
  marked 
  which 
  distinguish 
  it 
  from 
  

   allied 
  species. 
  It 
  would 
  be 
  impossible 
  to 
  imitate 
  its 
  colorings 
  

   which, 
  with 
  the 
  Scomberoids 
  generally, 
  is 
  gorgeous 
  beyond 
  de- 
  

   scription, 
  owing 
  to 
  the 
  variously 
  iridescent 
  hues 
  of 
  their 
  silvery 
  

   scales. 
  

  

  As 
  for 
  the 
  second 
  species 
  of 
  Selene, 
  described 
  by 
  Lacepfede, 
  

   there 
  can 
  be 
  no 
  doubt, 
  as 
  shown 
  by 
  Broussonet, 
  but 
  that 
  it 
  is 
  

   the 
  Chcetodon 
  Faber 
  of 
  Bloch, 
  or 
  Ephippus 
  Faber 
  of 
  Cuvier. 
  

  

  G-enus 
  SEtiEIVE 
  ; 
  Lac6p^de 
  (from 
  'Zi>^r\vv, 
  the 
  moon). 
  

   Body 
  ; 
  much 
  compressed 
  and 
  abbreviated. 
  

   Facial 
  outline; 
  nearly 
  vertical, 
  with 
  high 
  occipital 
  

  

  ridge. 
  

  

  Ventrals 
  ; 
  very 
  short 
  and 
  delicate. 
  

  

  First 
  dorsal 
  ; 
  low, 
  with 
  unequal 
  spinous 
  rays, 
  the 
  an- 
  

   terior 
  ones 
  longest. 
  

  

  Second 
  dorsal 
  ; 
  with 
  its 
  second 
  ray 
  long 
  and 
  fila- 
  

   mentous. 
  

  

  Anal; 
  resembling 
  second 
  dorsal, 
  with 
  shorter 
  filament. 
  

  

  In 
  the 
  above 
  characters, 
  it 
  will 
  be 
  seen 
  that 
  the 
  low 
  first 
  dorsal 
  and 
  short 
  ven- 
  

   trals 
  of 
  Vomer 
  are 
  combined 
  with 
  the 
  long 
  second 
  dorsal 
  and 
  anal 
  of 
  Argyreiosus, 
  

   If 
  these 
  characters 
  are 
  not 
  sufficient 
  to 
  constitute 
  a 
  new 
  genus, 
  then 
  this 
  species 
  

   becomes 
  a 
  Vomer. 
  At 
  any 
  rate, 
  it 
  forms 
  a 
  link 
  connecting 
  the 
  two 
  genera.

  In 
  general 
  appearance 
  and 
  color 
  it 
  resembles 
  Argyreiosus 
  

   Vomer, 
  and 
  in 
  some 
  respects, 
  Vo?ner 
  Brownii. 
  The 
  body 
  is 
  

   very 
  high 
  and 
  compressed, 
  and, 
  in 
  a 
  vertical 
  section, 
  taken 
  at 
  

   the 
  sixth 
  spine 
  of 
  the 
  first 
  dorsal, 
  thick 
  above, 
  wedge 
  shaped 
  

   below 
  : 
  the 
  height 
  being 
  five 
  times 
  as 
  great 
  as 
  the 
  thickness.
