  As 
  proved 
  by 
  the 
  next 
  specimen, 
  the 
  

   caudal 
  region 
  is 
  much 
  shortened 
  by 
  crushing. 
  A 
  coarsely 
  

   ornamented 
  elongated 
  plate 
  of 
  ill-defined 
  outline, 
  exposed 
  

   between 
  the 
  hinder 
  extremities 
  of 
  the 
  mandible, 
  is 
  not 
  

   improbably 
  an 
  infraclavicle. 
  A 
  portion 
  of 
  the 
  jaws 
  is 
  

   shown 
  enlarged 
  in 
  Egerton's 
  fig.

  and 
  some 
  of

  Remains 
  of 
  fish 
  about 
  0*6 
  in 
  length, 
  displaying 
  the 
  paired 
  

   fins 
  but 
  otherwise 
  very 
  imperfect. 
  Traces 
  of 
  the 
  endo- 
  

   skeleton 
  are 
  obscure, 
  and 
  the 
  upper 
  lobe 
  of 
  the 
  tail

  Two 
  imperfect 
  examples 
  of 
  thehead 
  and 
  abdominal 
  

   region, 
  the 
  second 
  showing 
  the 
  rays 
  of 
  the 
  dorsal 
  fin 
  and 
  

   noticed 
  by 
  Egerton, 
  loc. 
  cit. 
  Both 
  want 
  the 
  snout, 
  but 
  

   the 
  first 
  displays 
  the 
  hinder 
  portion 
  of 
  the 
  head 
  and 
  the 
  

   opercular 
  apparatus. 
  The 
  preoperculum 
  is 
  shown 
  to 
  

   extend 
  over 
  the 
  cheek 
  in 
  the 
  typical 
  Palseoniscid 
  manner 
  ; 
  

   and 
  there 
  seems 
  to 
  be 
  a 
  small 
  plate 
  above 
  the 
  upper 
  end 
  

   of 
  the 
  operculum.
