  Habitat. 
  — 
  Rana 
  iberica, 
  hitherto 
  observed 
  only 
  in 
  

   Portugal 
  and 
  North-western 
  Spain, 
  is 
  principally 
  

   bound 
  to 
  the 
  mountains, 
  where 
  it 
  is 
  found 
  up 
  to 
  

   4500 
  feet 
  or 
  even 
  higher. 
  It 
  has 
  been 
  obtained 
  in 
  

   Galicia 
  and 
  New 
  Castille 
  ; 
  in 
  the 
  Serra 
  de 
  Gerez, 
  the 
  

   Valle 
  Passos, 
  near 
  Coimbra 
  and 
  Beira, 
  the 
  Serra 
  de 
  

   Soajo, 
  near 
  Lisbon, 
  and 
  in 
  the 
  Serra 
  de 
  San 
  Mamede 
  ; 
  

   it 
  is 
  thus 
  on 
  record 
  from 
  all 
  the 
  provinces 
  of 
  Portugal 
  

   with 
  the 
  exception 
  of 
  Algarve. 
  

  

  This 
  species 
  has 
  also 
  been 
  recorded, 
  with 
  some 
  

   doubts 
  as 
  to 
  the 
  correctness 
  of 
  the 
  identification 
  of 
  

   a 
  single 
  specimen, 
  from 
  the 
  Lac 
  d'Aubert, 
  Hautes 
  

   Pyrenees, 
  by 
  Belloc 
  (C. 
  P. 
  Assoc. 
  Franc., 
  Pau, 
  1892, 
  

   ii, 
  p. 
  520). 
  This 
  specimen 
  was 
  probably 
  nothing 
  but 
  

   an 
  aberrant 
  and 
  badly 
  preserved 
  half-grown 
  Rana 
  

   temporaria. 
  

  

  I 
  am 
  indebted 
  to 
  the 
  kindness 
  of 
  Mr. 
  F. 
  A. 
  Moller, 
  

   of 
  the 
  Botanic 
  Gardens, 
  Coimbra, 
  for 
  the 
  specimens 
  

   figured 
  on 
  PI. 
  XXIII. 
  The 
  specimen 
  to 
  the 
  right 
  is 
  

   a 
  male, 
  that 
  to 
  the 
  left 
  a 
  female.
