  A

  of 
  mostly 
  fragmentary 
  specimens, 
  both 
  of 
  reptilian 
  and 
  

   piscine 
  remains, 
  have 
  been 
  obtained 
  from 
  the 
  supposed 
  Rhaetic 
  

   deposit 
  of 
  Linksfield, 
  but, 
  with 
  the 
  exception

  the 
  spines 
  and 
  teeth 
  

   of

  Ganoids, 
  pro- 
  

   bably 
  belonging 
  to 
  Semionotus,
