  In 
  the 
  tongue 
  and 
  vomerine 
  teeth 
  this 
  species 
  

   entirely 
  agrees 
  with 
  its 
  congener, 
  but 
  it 
  differs 
  in 
  the 
  

   occasioDal 
  presence 
  of 
  small, 
  grain-like 
  teeth 
  on 
  the 
  

   pterygoids 
  and 
  paraspheooid 
  ; 
  these 
  teeth 
  are 
  quite 
  

   rudimentary, 
  and 
  the 
  mucous 
  membrane 
  has 
  to 
  be 
  

   removed 
  to 
  ascertain 
  their 
  presence. 
  I 
  have 
  found 
  

   them 
  in 
  three 
  specimens 
  from 
  France 
  (Nantes, 
  Bor- 
  

   deaux, 
  south 
  of 
  France). 
  In 
  one 
  specimen 
  there 
  

   are 
  about 
  ten 
  teeth 
  on 
  the 
  parasphenoid, 
  at 
  the 
  base 
  

   of 
  the 
  longitudinal 
  branch 
  of 
  the 
  J.-shaped 
  bone, 
  and 
  

   two 
  pterygoid 
  teeth 
  close 
  together 
  on 
  the 
  left 
  side 
  ; 
  

   another 
  has 
  the 
  same 
  number 
  on 
  the 
  parasphenoid 
  and 
  

   a 
  series 
  of 
  four 
  on 
  the 
  pterygoids 
  ; 
  and 
  in 
  a 
  third 
  

   there 
  are 
  eight 
  teeth 
  on 
  the 
  right 
  pterygoid, 
  none 
  

   being 
  present 
  on 
  the 
  parasphenoid 
  nor 
  on 
  the 
  right 
  

   pterygoid. 
  

  

  * 
  The 
  genus 
  Didocus 
  was 
  founded 
  upon 
  a 
  young 
  specimen, 
  on 
  the 
  

   erroneous 
  assumption 
  that 
  in 
  Pelobates 
  cultripes 
  the 
  temporal 
  roof 
  is 
  

   developed 
  before 
  the 
  tail 
  of 
  the 
  larva 
  has 
  disappeared. 
  I 
  have 
  examined 
  

   the 
  skeleton 
  of 
  a 
  young 
  but 
  fully 
  transformed 
  specimen 
  from 
  Beziers, 
  

   Herault, 
  which 
  shows 
  both 
  a 
  large 
  fronto-parietal 
  fontanelle, 
  bordered 
  

   by 
  smooth 
  fronto-parietals, 
  and 
  an 
  uncovered 
  temple, 
  thus 
  answering 
  

   in 
  every 
  respect 
  the 
  definition 
  of 
  the 
  genus 
  so 
  rashly 
  established 
  by 
  

   Cope 
  more 
  than 
  twenty 
  years 
  ago, 
  and 
  still 
  maintained 
  by 
  him 
  in 
  his 
  

   latest 
  writings.
