  Type. 
  Nearly 
  complete 
  fish 
  ; 
  Palaeontological 
  Museum, 
  Munich. 
  

  

  A 
  small 
  species 
  attaining 
  a 
  length 
  of 
  about 
  0*3. 
  Length 
  of 
  head 
  

   with 
  opercular 
  apparatus 
  considerably 
  exceeding 
  the 
  maximum 
  

   depth 
  of 
  the 
  trunk, 
  and 
  somewhat 
  less 
  than 
  one-quarter 
  of 
  the 
  

   total 
  length 
  of 
  the 
  fish. 
  Caudal 
  region 
  little 
  tapering, 
  the 
  depth 
  of 
  

   the 
  caudal 
  pedicle 
  equalling 
  about 
  one-half 
  the 
  maximum 
  depth 
  of 
  

   the 
  trunk. 
  Teeth 
  large, 
  with 
  slender 
  apex, 
  and 
  irregularly 
  spaced. 
  

   Dorsal 
  fin 
  with 
  about 
  L8 
  rays, 
  deeper 
  than 
  long, 
  its 
  depth 
  equalling 
  

   at 
  least 
  three-quarters 
  that 
  of 
  the 
  trunk 
  at 
  its 
  origin 
  ; 
  all 
  the 
  fins 
  

   situated 
  as 
  in 
  the 
  type 
  species. 
  Scales 
  smooth. 
  

  

  According 
  to 
  Wagner 
  (loc. 
  cit. 
  p. 
  706), 
  the 
  imperfectly 
  described 
  

   Caturus 
  granulatus, 
  Miiuster 
  (Neues 
  Jahrb. 
  1842, 
  p. 
  44), 
  is 
  closely 
  

   related 
  to 
  this 
  species.
