  Habits. 
  — 
  This 
  species 
  is 
  a 
  burrower 
  in 
  sandy 
  locali- 
  

   ties, 
  digging 
  by 
  means 
  of 
  the 
  outer 
  edge 
  of 
  the 
  hands. 
  

   In 
  accordance 
  with 
  these 
  habits 
  its 
  lungs 
  are 
  more 
  

   developed 
  than 
  in 
  the 
  allied 
  species. 
  Bosca 
  having 
  

   found 
  the 
  male 
  carrying 
  the 
  eggs, 
  in 
  April, 
  there 
  is 
  no 
  

   doubt 
  the 
  breeding 
  habits 
  are 
  much 
  the 
  same 
  as 
  in 
  

   A. 
  ohstetricans, 
  although 
  the 
  pairing 
  has 
  not 
  yet 
  

   been 
  actually 
  observed. 
  The 
  tadpole 
  is 
  to 
  be 
  found 
  

   all 
  the 
  year 
  round. 
  

  

  Tadpole 
  (PL 
  I, 
  fig. 
  6). 
  — 
  I 
  am 
  not 
  able 
  to 
  detect 
  any 
  

   character 
  by 
  which 
  this 
  tadpole 
  may 
  be 
  surely 
  distin- 
  

   guished 
  from 
  that 
  of 
  A. 
  ohstetricans. 
  The 
  spots 
  on 
  the 
  

   tail 
  are, 
  however, 
  smaller, 
  more 
  crowded, 
  and 
  forming 
  

   vermiculations 
  on 
  the 
  muscular 
  portion, 
  the 
  space 
  oc- 
  

   cupied 
  by 
  the 
  lateral 
  groove 
  being 
  usually 
  free 
  from 
  

   spots. 
  

  

  Length 
  of 
  body, 
  20 
  mm. 
  ; 
  width 
  of 
  body, 
  15 
  mm. 
  ; 
  

   tail, 
  42 
  mm. 
  ; 
  depth 
  of 
  tail, 
  14. 
  

  

  Habitat. 
  — 
  Spain 
  (Aragon, 
  New 
  Castille, 
  Estrema- 
  

   dura) 
  and 
  Portugal 
  (Douro, 
  Beira, 
  and 
  Alemtejo). 
  

  

  The 
  specimen 
  figured 
  on 
  PI. 
  VIII 
  is 
  a 
  female, 
  one 
  of 
  

   the 
  types 
  from 
  Spain, 
  preserved 
  in 
  M. 
  Lataste's 
  col- 
  

   lection.
