  Heliolites

  As 
  far 
  as 
  one 
  can 
  judge 
  from 
  the 
  external 
  aspect, 
  size, 
  and 
  

  

  arrangement 
  of 
  the 
  corallites 
  in 
  a 
  small 
  fragment 
  of 
  a 
  corallum, 
  

  

  this 
  species 
  occurs 
  at 
  Keisley. 
  Schmidt 
  l 
  describes 
  it 
  from 
  the 
  

  

  Lyckholm 
  Beds, 
  Lindstrom 
  2 
  from 
  the 
  Leptcena-Limestone, 
  F. 
  Homer* 
  

  

  from 
  the 
  Sadewitz 
  pebbles, 
  3 
  and 
  Weissermel 
  4 
  from 
  those 
  of 
  Rosen- 
  

   berg. 
  

  

  Stenopoea 
  eibeosa, 
  Goldf. 
  

  

  This 
  species 
  is 
  of 
  common 
  occurrence 
  at 
  Keisley 
  and 
  Kildare. 
  

  

  Favosites 
  alveolaeis,

  The 
  Geological 
  Survey 
  of 
  Ireland 
  record 
  this 
  species 
  from 
  the 
  

   Chair 
  of 
  Kildare, 
  and 
  it 
  may 
  be 
  identical 
  with 
  the 
  variety 
  of 
  

   the 
  allied 
  F. 
  aspera 
  said 
  by 
  Schmidt 
  to 
  occur 
  in 
  the 
  Borkholm 
  

   zone. 
  F. 
  aspera 
  5 
  has 
  smaller 
  corallites 
  with 
  greater 
  irregularity 
  of 
  

   size.

  Prof. 
  H. 
  A. 
  Nicholson, 
  to 
  whom 
  I 
  am 
  indebted 
  for 
  kind 
  assistance 
  

   in 
  this 
  group 
  of 
  organisms, 
  informs 
  me 
  that 
  he 
  has 
  found 
  this 
  

   species 
  at 
  Keisley. 
  In 
  his 
  work 
  ' 
  Palaeozoic 
  Tabulate 
  Corals,' 
  he 
  

   says 
  (p. 
  327) 
  : 
  ' 
  The 
  only 
  known 
  species 
  of 
  Prasopora 
  [i.e. 
  Pr. 
  

   Grayce] 
  occurs 
  commonly 
  in 
  the 
  Craighead 
  Limestone 
  (Lower 
  

   Silurian) 
  of 
  Craighead, 
  near 
  Girvan, 
  Ayrshire/ 
  

  

  Note. 
  — 
  In 
  addition 
  to 
  the 
  above-mentioned 
  species, 
  there 
  are 
  

   several 
  indeterminable 
  zaphrentoid 
  corals 
  and 
  monticuliporoids 
  in 
  

   the 
  Keisley 
  Limestone. 
  Harkness 
  recorded 
  Nebulipora 
  lens 
  from 
  

   this 
  rock, 
  but 
  the 
  specimen 
  thus 
  labelled 
  in 
  the 
  Carlisle 
  Museum 
  is 
  

   very 
  indistinct 
  and 
  doubtful.
