  a 
  new 
  Species

  Among 
  some 
  Permian 
  Polyzoa 
  which 
  Mr. 
  Howse, 
  of 
  Newcastle, 
  

   entrusted 
  to 
  me 
  for 
  examination 
  was 
  one 
  labelled 
  " 
  Fenestella 
  

   ramosa." 
  This 
  I 
  at 
  once 
  saw 
  was 
  not 
  a 
  Fenestella, 
  but 
  a 
  Phnllo- 
  

   pora, 
  King, 
  a 
  new 
  and, 
  as 
  yet, 
  undescribed 
  species. 
  

  

  The 
  genus 
  Phyllopora 
  was 
  rightly 
  founded 
  by 
  King 
  * 
  to 
  receive 
  

   the 
  Permian 
  and 
  Silurian 
  species 
  of 
  Polyzoa 
  which, 
  prior 
  to 
  that 
  

   time, 
  had 
  been 
  referred 
  to 
  Betepora. 
  In 
  accordance 
  with 
  this 
  view 
  

   Mr. 
  Tine 
  has 
  recently 
  shown 
  that 
  among 
  the 
  ancient 
  Polyzoa, 
  so 
  

   far 
  as 
  at 
  present 
  ascertained, 
  we 
  have 
  none 
  of 
  the 
  peculiarities 
  of 
  

   cell-growth 
  which 
  are 
  characteristic 
  of 
  the 
  recent 
  Beteporce'X 
  ; 
  in 
  

   short, 
  that 
  we 
  have 
  no 
  Retepores 
  among 
  the 
  Palaeozoic 
  Polyzoa. 
  All 
  

   such 
  so-called 
  Retepores 
  should 
  be 
  now 
  assigned 
  to 
  Phyllopora, 
  

   King. 
  The 
  genus 
  Phyllopora 
  has 
  as 
  yet 
  been 
  but 
  imperfectly 
  

   worked 
  ; 
  its 
  rarity 
  in 
  the 
  more 
  recent 
  and 
  its 
  imperfect 
  preservation 
  

   in 
  the 
  older 
  rocks 
  go 
  far 
  to 
  account 
  for 
  this. 
  Tt 
  is 
  of 
  interest 
  as 
  one 
  

   of 
  the 
  earliest 
  of 
  our 
  Paleozoic 
  Polyzoa.
