   The

  on 
  the 
  upper 
  portion 
  are 
  reddish 
  purple 
  with 
  white 
  tips 
  ;

  A 
  specimen 
  of 
  this 
  species, 
  presented

  Molpadia 
  coriacea, 
  Hutton. 
  

  

  This 
  is 
  evidently 
  not 
  a 
  true 
  Moljmdia. 
  It 
  is 
  probably 
  a 
  Caudina 
  or 
  an 
  

   Echi?iosama, 
  but 
  as 
  the 
  type 
  is 
  in 
  the 
  Wellington 
  Museum, 
  I 
  cannot 
  

   re-examine 
  it.

  The 
  receipt 
  of 
  another 
  specimen 
  of 
  the 
  Chirodota 
  (? 
  ) 
  alba 
  of 
  my 
  catalogue 
  

   has 
  enabled 
  me 
  to 
  dissect 
  it, 
  and 
  I 
  find 
  that 
  it 
  has 
  five 
  well-marked 
  

   ambulacra, 
  and 
  should 
  be 
  placed 
  in 
  the 
  genus 
  Echinocucumis.
