  Burnup,

  this 
  species

  writing 
  from 
  

   Tongaat 
  on 
  18th 
  Januaiy,

  says 
  : 
  — 
  

  

  '' 
  Tlie 
  Helicarion

  ? 
  scarcely 
  agrees 
  with 
  anything 
  that 
  I 
  

   know 
  (speaking 
  from 
  memory, 
  for 
  I 
  am 
  away 
  from 
  all 
  

   opportunity 
  of 
  comparing), 
  but 
  it 
  seems 
  nearest 
  to 
  the 
  

   specimen, 
  which 
  you 
  will 
  now 
  have, 
  sent 
  to 
  me 
  by

   sonby

  I 
  should 
  

   say 
  probably 
  erroneously, 
  been 
  identified 
  as 
  H. 
  corneas, 
  

  

  It 
  is 
  very 
  close 
  to 
  that 
  species, 
  hut 
  the 
  anatomy 
  is 
  not 
  

   quite 
  the
