  This 
  genus 
  differs 
  from 
  Siphostorna 
  chielly 
  in 
  the 
  position 
  of 
  the 
  egg-pouch 
  of 
  the 
  

   male, 
  which 
  is 
  under 
  the 
  abdomen 
  instead 
  of 
  the 
  tail. 
  The 
  angles 
  of 
  the 
  body 
  are 
  

   strongly 
  ridged.

  The 
  family 
  Hippocampidce 
  should 
  be, 
  apparently,

  The 
  reasons 
  for 
  using 
  the 
  name 
  Macrorhamphosus 
  for 
  this 
  genus 
  instead 
  of 
  Centris- 
  

   cus 
  are 
  stated 
  in 
  Proc. 
  U. 
  S. 
  Nat. 
  Mus., 
  1882,

  The 
  original 
  type 
  of 
  Centriscus 
  is 
  C. 
  

   scutatus.

  discussion
