  Belemnites 
  abhreviatus 
  is 
  the 
  one 
  species 
  which 
  allies 
  the 
  Kim- 
  

   meridge 
  fauna 
  with 
  the 
  Corallian 
  and 
  Oxfordian 
  below. 
  The 
  Jurassic 
  

   Dibranchiata 
  die 
  out 
  with 
  the 
  close 
  of 
  the 
  Kimmeridge. 
  These 
  last 
  

   Jurassic 
  Decapoda 
  are 
  Bel. 
  contortus, 
  Bel. 
  eocGentricus, 
  Bel. 
  earplanatus, 
  

   Bel. 
  lateralis, 
  Bel. 
  nitidus, 
  Bel. 
  Souichii, 
  and 
  Bel. 
  Troslyanus. 
  ~No

  Britain 
  or

  TeuthidcB. 
  — 
  Coccoteuthis 
  latvpinnis, 
  Owen. 
  This 
  genus, 
  com- 
  

   bining 
  some 
  of 
  the 
  characters 
  of 
  the 
  Sepia 
  with 
  those 
  of 
  Loligo, 
  

   Sepioteuthis, 
  &c, 
  is 
  extremely 
  rare, 
  and 
  is 
  only 
  known 
  in 
  the 
  Upper 
  

   Kimmeridge 
  beds. 
  This 
  family 
  being 
  rarely 
  preserved 
  in 
  the 
  Ju- 
  

   rassic 
  rocks, 
  I 
  have 
  kept 
  separate 
  : 
  only 
  4 
  genera 
  and 
  5 
  species 
  are 
  

   known 
  throughout 
  the 
  whole 
  of 
  the 
  Jurassic 
  period; 
  they 
  are 
  Geo- 
  

   teuthis 
  bollensis, 
  from 
  the 
  Lower 
  Lias, 
  Beloteuthis 
  Leckenbyi 
  and 
  

   B. 
  subcostatus, 
  Upper 
  Lias, 
  Acanthoteuthis 
  antiquus, 
  Oxford 
  Clay, 
  

   and 
  the 
  above 
  Coccoteuthis 
  latipinnis, 
  Kimmeridge. 
  It 
  is 
  probable 
  

   that 
  in 
  old 
  collections 
  and 
  amongst 
  the 
  numerous 
  remains 
  of 
  the 
  

   Dibranchiata 
  from 
  the 
  Oxford 
  Clay 
  of 
  Christian 
  Malford 
  and 
  Chip- 
  

   penham 
  other 
  species 
  may 
  be 
  found 
  ; 
  individually 
  they 
  occur 
  in 
  large 
  

   numbers. 
  

  

  Pisces. 
  — 
  Every 
  species 
  in 
  the 
  Kimmeridge 
  Clay 
  is 
  confined 
  to 
  it. 
  

   There 
  are 
  11 
  genera 
  and 
  14 
  species. 
  These 
  11 
  genera 
  represent 
  no 
  

   less 
  than 
  5 
  families 
  ; 
  the 
  Sauroidei, 
  through 
  Bitaxiodus 
  and 
  Thlatto- 
  

   dus; 
  the 
  Cestraciontidae, 
  through 
  Asteracanthus 
  and 
  JStrophodus 
  ; 
  

   the 
  Pycnodontidae, 
  through 
  Gyrodus, 
  Gyronchus, 
  Pycnodus, 
  and 
  

   Splicerodus 
  ; 
  the 
  Placoidei, 
  through 
  Hybodus 
  and 
  Sphenonclius 
  ; 
  and 
  

   the 
  Coelacanthini, 
  through 
  Macropoma. 
  

  

  Reptilia. 
  — 
  The 
  largest 
  number 
  of 
  Reptilia, 
  either 
  in 
  genera 
  or 
  

   species, 
  known 
  in 
  the 
  Secondary 
  rocks 
  of 
  Britain 
  occur 
  in 
  the 
  Kim- 
  

   meridge 
  Clay. 
  Six 
  orders 
  are 
  represented, 
  viz. 
  the 
  Chelonia, 
  Croco- 
  

   dilia, 
  Ichthyopterygia, 
  Sauropterygia, 
  Pterosauria, 
  and 
  Dinosauria 
  ; 
  

   these 
  6 
  orders 
  contain 
  17 
  genera 
  and 
  45 
  species.
