  The 
  internasals 
  are 
  broadly 
  contiguous 
  in 
  No. 
  65552 
  and 
  touch 
  

   each 
  other 
  only 
  by 
  their 
  inner 
  angle 
  in 
  No. 
  65599. 
  The 
  degree 
  of 
  

   contiguity 
  of 
  the 
  internasals 
  is 
  very 
  variable 
  among 
  all 
  the 
  specimens 
  

   of 
  Elapomorplius 
  having 
  a 
  single 
  prefrontal, 
  according 
  to 
  my 
  ex- 
  

   perience. 
  Boulenger's 
  key 
  for 
  the 
  differentiation 
  of 
  these 
  species, 
  

   which 
  is 
  based 
  on 
  this 
  character, 
  is 
  therefore 
  quite 
  unreliable.
