  Tadpole 
  (PI. 
  I, 
  fig. 
  3). 
  — 
  One 
  very 
  striking 
  character 
  

   distinguishes 
  this 
  tadpole 
  from 
  the 
  preceding, 
  viz. 
  the 
  

   shape 
  of 
  the 
  mouth, 
  which 
  is 
  elliptical 
  as 
  in 
  other 
  

   genera 
  of 
  Biscoglossidse. 
  The 
  tail 
  is, 
  as 
  a 
  rule, 
  rather 
  

   shorter, 
  and 
  the 
  muciferous 
  crypts 
  are 
  hardly 
  distin- 
  

   guishable 
  in 
  the 
  tadpoles 
  obtained 
  by 
  me 
  ; 
  however, 
  

   it 
  is 
  very 
  probable 
  that 
  the 
  latter 
  difference 
  would 
  not 
  

   prove 
  constant 
  if 
  tested 
  on 
  more 
  extensive 
  material.
