  A 
  species 
  closely 
  resembling 
  T. 
  microdon, 
  but 
  described 
  by 
  

   Bassani 
  as 
  distinguished 
  from 
  the 
  latter 
  by 
  the 
  greater 
  development 
  

   of 
  the 
  pectoral 
  fins, 
  the 
  more 
  remote 
  situation 
  of 
  the 
  pelvic 
  fins, 
  the 
  

   slightly 
  greater 
  number 
  of 
  vertebra3, 
  and 
  other 
  characters.

  An 
  indefinable 
  large 
  species 
  apparently 
  related 
  to

   and

  heckeli,

  known 
  only 
  from 
  the 
  undermentioned 
  fragments. 
  

   The 
  head 
  seems 
  to 
  have 
  been 
  comparatively 
  small 
  and 
  the 
  trunk 
  

   deep 
  ; 
  the 
  length 
  of 
  the 
  head 
  with 
  opercular 
  apparatus 
  being 
  less 
  

   than 
  the 
  maximum 
  depth 
  of 
  the 
  trunk. 
  The 
  small 
  dorsal 
  fin 
  

   arises 
  behind 
  the 
  origin 
  of 
  the 
  anal 
  fin.
