  more 
  coarsely 
  and 
  sharply 
  granulate; 
  the 
  distal 
  of 
  the 
  two 
  vertical 
  

   rows 
  of 
  granules 
  inside 
  the 
  palm 
  is 
  composed 
  of 
  very 
  fine 
  granules; 
  

   the 
  three 
  denticles 
  on 
  the 
  movable 
  finger 
  are 
  all 
  more 
  proximally 
  

   placed, 
  and 
  the 
  intermediate 
  one 
  has 
  a 
  much 
  smaller 
  space 
  on 
  its 
  

   proximal 
  than 
  on 
  its 
  distal 
  side. 
  

  

  While 
  it 
  is 
  possible 
  that 
  this 
  specimen 
  represents 
  a 
  new 
  species, 
  it 
  

   is 
  too 
  undeveloped 
  to 
  be 
  described 
  as 
  such.
