  Cestraciox 
  Cuvicr 
  (Regne 
  Animal, 
  type 
  Cestracion 
  philippi 
  Blocli 
  and 
  Schneider) 
  

   should 
  perhaps 
  be 
  adopted 
  instead 
  of 
  Heterodontus 
  Blainville, 
  preoccupied 
  in 
  Herpe- 
  

   tology 
  as 
  Heterodon. 
  Both 
  words 
  are 
  from 
  erepoi, 
  66<bv 
  (odovS), 
  and 
  are 
  correctly 
  

   written 
  Heterodus 
  or 
  Hcterodon, 
  not 
  Heterodontus. 
  Cestracion 
  is 
  an 
  old 
  name 
  of 
  the 
  

   Hammerheaded 
  shark, 
  from 
  ite'tfrpa, 
  a 
  pick-axe, 
  or 
  similar 
  instrument.
