  -Carcharias 
  Rafinesque 
  was 
  established 
  for 
  those 
  sharks, 
  "the 
  most 
  enormous 
  and 
  

   most 
  voracious 
  of 
  their 
  order, 
  which 
  differ 
  from 
  the 
  genus 
  Galeus 
  Rafinesque, 
  by 
  

   the 
  lack 
  of 
  spiracles." 
  But 
  one 
  species 
  (Carcharias 
  taurus 
  Rafinesque) 
  is 
  mentioned, 
  

   and 
  this 
  species, 
  although 
  really 
  possessing 
  spiracles, 
  must 
  be 
  regarded 
  as 
  the 
  type 
  ot 
  

   Carcharias. 
  This 
  name 
  should 
  therefore 
  supersede 
  Odoutaspis.
