  This 
  genus 
  includes 
  two 
  species 
  : 
  — 
  F. 
  punctahts, 
  

   Fitz., 
  of 
  Western 
  Continental 
  Europe, 
  and 
  P. 
  caucasi- 
  

   cus, 
  Blgr., 
  recently 
  discovered 
  on 
  the 
  Asiatic 
  side 
  of 
  

   the 
  Caucasus 
  at 
  an 
  altitude 
  of 
  7000 
  feet. 
  The 
  latter 
  

   has 
  been 
  made 
  the 
  type 
  of 
  a 
  distinct 
  genus, 
  Pelody- 
  

   tojjsis, 
  by 
  Nikolski, 
  on 
  grounds 
  too 
  trivial 
  to 
  deserve 
  

   recognition. 
  

  

  Perhaps 
  this 
  Pelodytes 
  caucasicus 
  may 
  yet 
  be 
  found 
  

   in 
  Cis-Caucasia, 
  and 
  yield 
  a 
  further 
  addition 
  to 
  the 
  

   European 
  fauna. 
  It 
  is 
  distinguished 
  from 
  its 
  con- 
  

   gener 
  in 
  the 
  longer 
  hind 
  limbs, 
  the 
  tibio-tarsal 
  articu- 
  

   lation 
  reaching 
  the 
  tip 
  of 
  the 
  snout, 
  and 
  the 
  somewhat 
  

   more 
  posterior 
  position 
  of 
  the 
  groups 
  of 
  vomerine 
  

   teeth; 
  the 
  toes 
  are 
  not 
  so 
  strongly 
  fringed 
  in 
  the 
  

   male, 
  the 
  fore 
  limbs 
  are 
  more 
  robust, 
  and 
  the 
  black 
  

   horny 
  nuptial 
  excrescences 
  are 
  much 
  more 
  strongly 
  

   developed 
  on 
  the 
  warts 
  and 
  ridges 
  of 
  the 
  upper 
  sur- 
  

   faces.
