  An 
  undescribed 
  right 
  splenial 
  of 
  Mesodon, 
  with 
  very 
  irregular 
  

   teeth, 
  from 
  the 
  Jurassic 
  of 
  Mejdel 
  Shems, 
  near 
  Caesarea 
  Philippi, 
  is 
  

   preserved 
  in 
  the 
  Museum 
  of 
  the 
  Syrian 
  Protestant 
  College, 
  Beyrout. 
  

  

  Indeterminable 
  detached 
  teeth 
  and 
  miscellaneous 
  portions 
  of 
  

   jaws 
  with 
  widely 
  spaced 
  teeth, 
  apparently 
  of 
  Mesodon, 
  are 
  recorded 
  

   from 
  the 
  Neocomian 
  of 
  Europe 
  under 
  the 
  name 
  of 
  Pycnodus 
  couloni 
  ; 
  

   but 
  the 
  specific 
  characters 
  even 
  of 
  the 
  dentition 
  are 
  not 
  as 
  yet 
  

   defined. 
  The 
  name 
  has 
  been 
  given 
  to 
  detached 
  teeth
