  Brittany, 
  in 
  the 
  plains 
  as 
  well 
  as 
  in 
  the 
  hills, 
  but 
  

   very 
  local 
  in 
  many 
  parts, 
  and 
  does 
  not 
  ascend 
  the 
  

   Pyrenees 
  ; 
  South-eastern 
  Holland 
  ; 
  Belgium 
  south 
  of 
  

   the 
  Sambre 
  and 
  the 
  Meuse, 
  and 
  in 
  the 
  calcareous 
  

   localities 
  near 
  Tournay 
  ; 
  Germany 
  all 
  along 
  tbe 
  Rhine, 
  

   but 
  not 
  higher 
  up 
  than 
  2000 
  feet 
  in 
  Baden 
  ; 
  South 
  

   Germany, 
  Switzerland, 
  in 
  the 
  valleys 
  as 
  well 
  as 
  on 
  

   the 
  mountains 
  up 
  to 
  3900 
  feet. 
  East 
  of 
  the 
  Weser 
  in 
  

   Germany 
  this 
  species 
  enters 
  into 
  competition 
  with 
  

   i>. 
  igneus, 
  and, 
  as 
  first 
  pointed 
  out 
  by 
  Wolterstorff, 
  

   becomes 
  restricted 
  to 
  the 
  hills 
  ; 
  this 
  being 
  the 
  case 
  

   wherever 
  the 
  two 
  s^Decies 
  co-exist, 
  as 
  in 
  Austria- 
  

   Hungary 
  and 
  Moldavia. 
  Its 
  highest 
  recorded 
  oc- 
  

   currence 
  in 
  Transylvania 
  is 
  at 
  3900 
  feet, 
  as 
  in 
  

   Switzerland, 
  whilst 
  in 
  the 
  Tyrol 
  it 
  reaches 
  to 
  4850 
  

   feet, 
  and 
  in 
  Bosnia 
  to 
  5500 
  feet. 
  In 
  Italy 
  the 
  

   species 
  is 
  found 
  in 
  Lombardy 
  and 
  Yenetia,* 
  in 
  the 
  

   Apuan 
  Alps 
  up 
  to 
  4500 
  feet, 
  and 
  along 
  the 
  chain 
  of 
  

   the 
  Apennines 
  from 
  Emilia 
  to 
  Calabria, 
  between 
  600 
  

   and 
  3600 
  feet, 
  as 
  I 
  am 
  informed 
  by 
  Prof. 
  Giglioli. 
  It 
  

   is 
  on 
  record 
  from 
  the 
  Etna, 
  but 
  not 
  from 
  other 
  parts 
  of 
  

   Sicily. 
  East 
  of 
  the 
  Adriatic 
  it 
  occurs 
  in 
  Dalmatia, 
  

   Bosnia, 
  Herzegovina, 
  Montenegro, 
  Turkey 
  (Adria- 
  

   nople), 
  and 
  Greece 
  (Parnassos, 
  3000 
  feet). 
  

  

  Mehely 
  has 
  recently 
  expressed 
  the 
  opinion 
  that 
  

   B. 
  pachypus 
  is 
  to 
  be 
  regarded 
  as 
  a 
  typical 
  hill 
  or 
  

   mountain 
  form, 
  which 
  only 
  descends 
  to 
  the 
  plain 
  in 
  

   the 
  cooler 
  northern 
  regions, 
  like 
  Rana 
  temijoraria. 
  

   This 
  is 
  certainly 
  not 
  the 
  case. 
  In 
  the 
  south-west 
  of 
  

   France 
  the 
  species 
  is 
  quite 
  abundant 
  at 
  sea 
  level 
  ; 
  I 
  

   have 
  myself 
  collected 
  it 
  on 
  the 
  banks 
  of 
  the 
  Garonne, 
  

   in 
  the 
  immediate 
  vicinity 
  of 
  Bordeaux, 
  where 
  it 
  is 
  

   plentiful 
  in 
  small 
  ditches 
  bordering 
  the 
  vineyards 
  ; 
  

   and 
  E. 
  de 
  Betta 
  found 
  it 
  numerous 
  in 
  tbe 
  plains 
  

   of 
  Yenetia. 
  

  

  * 
  The 
  species 
  is 
  absent 
  from 
  Piedmont. 
  Some 
  hundred 
  specimens 
  

   from 
  Yenetia 
  were 
  turned 
  loose 
  in 
  the 
  neighbourhood 
  of 
  Turin 
  by 
  

   Count 
  Peracca 
  about 
  ten 
  years 
  ago.
