  Only 
  7 
  species 
  are 
  known 
  in 
  the 
  zone 
  of 
  Arietites 
  BucMaadi, 
  

   and 
  the 
  same 
  7 
  occnr 
  also 
  in 
  the 
  Angulatum-beds 
  below 
  ; 
  other- 
  

   wise 
  the 
  f 
  annas 
  of 
  the 
  two 
  zones 
  differ 
  essentially. 
  These 
  7 
  corals 
  

   are 
  Moatlivaltia 
  Gudtardi, 
  Septastrcea 
  evesJiami, 
  Lepidophyllia 
  

   Strieklandi, 
  Isastrcea 
  enclotJiecata, 
  I. 
  insignis, 
  I. 
  Stricklandi, 
  and 
  

   Cyathocoema 
  globosa. 
  The 
  preponderance 
  of 
  Cephalopoda 
  in 
  these 
  

   beds 
  is 
  a 
  marked 
  feature, 
  especially 
  at 
  Lyme 
  Regis, 
  where 
  the 
  

   Bucklandi-beds 
  are 
  nearly 
  100 
  feet 
  in 
  thickness. 
  The 
  same 
  horizon 
  

   in 
  Yorkshire, 
  at 
  Robin 
  Hood's 
  Bay 
  and 
  Redcar, 
  is 
  hidden 
  or 
  covered 
  

   at 
  high 
  water, 
  and 
  ranges 
  under 
  the 
  German 
  Ocean. 
  The 
  Cote 
  d'Or 
  

   in 
  France 
  exhibits 
  these 
  Bncklandi-beds 
  with 
  a 
  rich 
  fauna, 
  no 
  less 
  

   than 
  52 
  species 
  of 
  Ammonites 
  alone 
  occurring 
  therein. 
  

  

  !N"o 
  corals 
  are 
  known 
  in 
  the 
  Turneri-beds, 
  and 
  only 
  2 
  species 
  

   appear 
  to 
  have 
  come 
  from 
  the 
  Obtusus-Skales 
  and 
  Limestone 
  bands, 
  

   although 
  physically 
  the 
  zone 
  is 
  thick, 
  being 
  nearly 
  100 
  feet. 
  

   Many 
  genera 
  of 
  fish 
  and 
  Saurians 
  occur 
  in 
  the 
  Obtusus-series 
  at 
  Lyme 
  

   Regis. 
  In 
  Xorth 
  and 
  South 
  Germany 
  and 
  France 
  the 
  species 
  are 
  

   the 
  same 
  as 
  those 
  of 
  Britain. 
  

  

  jSTo 
  Actinozoa 
  have 
  been 
  detected 
  in 
  the 
  zone 
  of 
  Amaltheus 
  oxynotus, 
  

   either 
  at 
  Lyme 
  Regis 
  or 
  Cheltenham, 
  or 
  at 
  Robin 
  Hood's 
  Bay 
  in 
  

   Yorkshire. 
  

  

  The 
  succeeding 
  series 
  of 
  shales 
  and 
  clays, 
  composing 
  the 
  Arietites- 
  

   raricostatus 
  zone, 
  have 
  yielded 
  4 
  species, 
  viz. 
  Montlivaltia 
  rugosa, 
  M. 
  

   mucronata, 
  M. 
  radiata, 
  and 
  M. 
  nummiformis.
