  Concerning 
  the 
  mutual 
  affinities 
  of 
  the 
  fossil 
  Coral-fauna 
  of 
  the 
  

   West 
  Indian 
  Islands, 
  and 
  the 
  recent 
  Coral-fauna 
  of 
  the 
  Pacific 
  Ocean, 
  

   South 
  Seas, 
  and 
  Indian 
  Ocean, 
  as 
  well 
  as 
  of 
  the 
  European 
  and 
  West 
  

   Indian 
  Miocene 
  Coral-faunae, 
  the 
  generalizations 
  which 
  were 
  the 
  

   result 
  of 
  the 
  study 
  of 
  the 
  species 
  described 
  in 
  the 
  first 
  part 
  of 
  this 
  

   communication 
  are 
  strengthened 
  and 
  are 
  rendered 
  more 
  striking 
  by 
  

   the 
  examination 
  of 
  the 
  recent 
  accession 
  to 
  the 
  Heneken 
  Collection. 
  

  

  Ceratotrochus 
  duodecimcostatus, 
  Trochocyathus 
  latero-spinosus, 
  and 
  

   Stylophora 
  raristella, 
  well-known 
  European 
  Miocene 
  species, 
  are 
  con- 
  

   tained 
  in 
  the 
  collection 
  ; 
  the 
  genus 
  Pocillopora 
  is 
  also 
  represented, 
  

   although 
  unknown 
  in 
  the 
  present 
  Caribbean 
  seas. 
  There 
  are 
  several 
  

   specimens 
  of 
  a 
  new 
  Trochocyathus 
  possessing 
  some 
  unusual 
  anato- 
  

   mical 
  peculiarities 
  which 
  lessen 
  the 
  distance 
  between 
  the 
  Turbino- 
  

   liclce 
  and 
  the 
  Astraiides 
  ; 
  whilst 
  some 
  magnificent 
  simple 
  Corals 
  are 
  

   intermediate 
  between 
  the 
  genera 
  Montlivaltia 
  and 
  Circophyllia. 
  Two 
  

   species 
  of 
  a 
  new 
  genus, 
  belonging 
  to 
  the 
  family 
  of 
  Compound 
  

   Astrceans, 
  are 
  described; 
  they 
  present 
  the 
  greatest 
  elaboration 
  of 
  

   structural 
  details 
  I 
  have 
  ever 
  seen 
  amongst 
  Corals, 
  and 
  aro 
  most 
  

   complicated.
