  The 
  following 
  paper 
  contains 
  an 
  account 
  of 
  the 
  Acrgeinse 
  

   that 
  were 
  captured 
  by 
  Burchell 
  in 
  Brazil. 
  According 
  to 
  the 
  

   interpretation 
  at 
  which 
  I 
  have 
  arrived 
  in 
  consultation 
  with 
  

   Professor 
  Poulton, 
  F.R.S., 
  and 
  Mr. 
  W.
