  Habitat. 
  — 
  Discoglossns 
  pictus 
  inhabits 
  South-western 
  

   Europe 
  and 
  North-west 
  Africa. 
  It 
  is 
  found 
  nearly 
  all 
  

   over 
  Central, 
  Western, 
  and 
  Southern 
  Spain 
  and 
  

   Portugal, 
  but 
  appears 
  to 
  be 
  absent 
  from 
  the 
  east 
  coast 
  

   as 
  well 
  as 
  from 
  the 
  Balearic 
  Islands, 
  a 
  fact 
  which 
  is 
  the 
  

   more 
  surprising 
  since 
  the 
  species 
  is 
  again 
  abundant 
  in 
  

   Corsica, 
  Giglio, 
  Montecristo, 
  Sardinia, 
  Sicily 
  and 
  small 
  

   neighbouring 
  islands, 
  Malta 
  and 
  Gozo. 
  In 
  Africa 
  its 
  

   habitat 
  extends 
  all 
  over 
  Morocco, 
  Algeria, 
  and 
  Tunisia 
  

   north 
  of 
  the 
  Sahara; 
  also 
  on 
  G-alita 
  Island, 
  ofi" 
  the 
  

   coast 
  of 
  Tunisia. 
  It 
  inhabits 
  the 
  coasts 
  and 
  plains 
  as 
  

   well 
  as 
  the 
  hills, 
  having 
  been 
  found 
  by 
  Bedriaga 
  in 
  

   Corsica 
  from 
  sea 
  level 
  to 
  an 
  altitude 
  of 
  2450 
  feet. 
  

  

  The 
  occurrence 
  of 
  JJiscocjlossus 
  in 
  Santa 
  Maura, 
  

   Ionian 
  Islands, 
  whence 
  a 
  single 
  specimen 
  is 
  stated 
  by 
  

   De 
  Betta 
  to 
  have 
  been 
  obtained 
  by 
  the 
  late 
  A. 
  Ninni 
  

   in 
  1863, 
  has 
  not 
  been 
  confirmed 
  bv 
  more 
  recent 
  ex- 
  

   plorers 
  of 
  those 
  islands, 
  and 
  Bedriaga 
  informs 
  us 
  that 
  

   the 
  specimens 
  put 
  np 
  under 
  that 
  name 
  in 
  the 
  Athens 
  

   Museum 
  belons; 
  to 
  Bana 
  esculenta. 
  

  

  A 
  few 
  years 
  ago 
  the 
  late 
  Heron-Roy 
  er 
  introduced 
  

   the 
  species 
  into 
  France 
  near 
  Amboise, 
  in 
  Touraine, 
  

   where 
  it 
  appears 
  to 
  have 
  become 
  perfectly 
  acclimatised. 
  

   Several 
  thousands 
  of 
  young 
  specimens 
  have 
  also 
  been 
  

   turned 
  loose 
  in 
  the 
  neighbourhood 
  of 
  Argenton, 
  dep. 
  

   Indre, 
  by 
  M. 
  Rollinat 
  in 
  1892 
  and 
  1893.

  I
