  An 
  indeterminable 
  specimen 
  from 
  a 
  so-called 
  Jurassic 
  horizon 
  

   at 
  Bogoslowsk, 
  Siberia, 
  is 
  described 
  by 
  G. 
  Eischer 
  de 
  Waldheim 
  

   under 
  the 
  new 
  generic 
  and 
  specific 
  name 
  of 
  Prionopleurus 
  bronni 
  

   (Bull.

  The 
  description 
  is 
  unsatisfactory, 
  and 
  whether 
  

   or 
  not 
  the 
  fossil 
  is 
  related 
  to 
  Tetragonolepis 
  remains 
  to 
  be 
  

   determined.
