  Prof.

  Chun 
  on 
  the 
  

  

  all 
  combine 
  to 
  mark 
  Stephanophyes 
  as 
  one 
  of 
  the 
  most 
  splen- 
  

   did 
  objects 
  among 
  pelagic 
  animals. 
  

  

  Unfortunately 
  its 
  extraordinary 
  delicacy 
  presents 
  great 
  

   difficulties 
  to 
  investigation. 
  Within 
  an 
  hour 
  or 
  two 
  of 
  its 
  

   capture 
  it 
  begins 
  to 
  melt 
  away, 
  and 
  none 
  of 
  the 
  modes 
  of 
  

   preservation 
  employed 
  with 
  good 
  results 
  upon 
  other 
  Siphono- 
  

   phora 
  sufficed 
  even 
  to 
  preserve 
  fragments 
  tolerably 
  well. 
  

  

  From 
  January 
  to 
  March 
  it 
  occurred 
  rarely 
  and 
  singly. 
  In 
  

   old 
  specimens 
  the 
  stem 
  appears 
  to 
  break 
  up 
  into 
  fragments 
  

   which 
  are 
  occasionally 
  met 
  with 
  floating. 
  Stephanophyes 
  

   passes 
  through 
  a 
  remarkable 
  metamorphosis. 
  The 
  youngest 
  

   specimens, 
  perfectly 
  transparent 
  and 
  therefore 
  easily 
  escaping 
  

   even 
  the 
  practised 
  eye, 
  display 
  throughout 
  the 
  characters 
  of 
  

   the 
  genus 
  Lilyopsis 
  ; 
  they 
  possess 
  two 
  nectocalyces 
  with 
  the 
  

   flnid-canal 
  only 
  once 
  dichotomously 
  divided, 
  and 
  are 
  com- 
  

   pletely 
  destitute 
  of 
  the 
  heteromcrphous 
  tentacles 
  on 
  the 
  inter- 
  

   nodes 
  of 
  the 
  older 
  groups. 
  These 
  tentacles 
  are 
  subsequently 
  

   formed 
  between 
  the 
  younger 
  groups, 
  and 
  at 
  the 
  same 
  time 
  a 
  

   more 
  abundant 
  dichotomy 
  of 
  the 
  fluid-canals 
  makes 
  its 
  

   appearance 
  even 
  in 
  the 
  reserve-nectocalyces. 
  

  

  Thus 
  Stephanophyes 
  constitutes 
  a 
  typical 
  bond 
  of 
  union 
  

   between 
  the 
  Prayidai 
  and 
  the 
  Polyphyida?, 
  while, 
  on 
  the 
  other 
  

   hand, 
  the 
  occurrence 
  of 
  heteromorphous 
  tentacles 
  with 
  small, 
  

   astomatous, 
  feeler-like 
  polyps 
  points 
  towards 
  the 
  structural 
  

   conditions 
  of 
  the 
  Physophoridae.

  In 
  conclusion, 
  I 
  give 
  a 
  summary 
  of 
  the 
  Canarian 
  Calyco- 
  

   phorida3 
  which 
  produce 
  Eudoxite, 
  adding 
  the 
  names 
  of 
  the 
  

   authors 
  who 
  demonstrated 
  the 
  relation 
  of 
  the 
  so-called 
  

   monogastric 
  colonies 
  to 
  the 
  polygastric 
  forms.
