  in

  says 
  : 
  — 
  " 
  It 
  is 
  not 
  without 
  some 
  hesitation 
  that 
  we 
  place 
  

   Canutes 
  in 
  the 
  class 
  of 
  Polypi, 
  the 
  form 
  of 
  the 
  calices 
  resembling 
  

   very 
  much 
  what 
  is 
  met 
  with 
  in

  Bryozoa. 
  In 
  the 
  present 
  

   state 
  of 
  our 
  knowledge 
  concerning 
  the 
  structure 
  of 
  these 
  fossils, 
  their 
  

   zoological 
  affinities 
  cannot 
  be 
  determined 
  with

  but 
  we 
  are 
  

   inclined 
  to 
  think 
  that

  are

  the
