  of 
  July, 
  sometimes 
  as 
  late 
  as 
  September, 
  as 
  observed 
  

   by 
  Pfliiger 
  near 
  Bonn. 
  Specimens 
  from 
  Belgium 
  kept 
  

   by 
  me 
  in 
  confinement 
  were 
  still 
  pairing 
  on 
  August 
  

   18tli, 
  and 
  Mr. 
  A. 
  Pam 
  informs 
  me 
  that 
  some 
  brought 
  

   home 
  by 
  him 
  this 
  summer 
  from 
  Switzerland 
  were 
  ob- 
  

   served 
  in 
  embrace 
  as 
  late 
  as 
  October 
  13th. 
  

  

  Mehely 
  found 
  spawn 
  as 
  early 
  as 
  the 
  2nd 
  of 
  May 
  in 
  

   Transylvania. 
  Spallanzani, 
  in 
  the 
  last 
  century, 
  ob- 
  

   served 
  it 
  pairing 
  in 
  May 
  in 
  the 
  mountains 
  near 
  

   Modena, 
  and 
  he 
  tells 
  us 
  that 
  during 
  his 
  journey 
  to 
  

   Switzerland 
  in 
  1779 
  the 
  same 
  species 
  was 
  pairing 
  in 
  

   July 
  and 
  August. 
  I 
  have 
  myself 
  observed 
  it 
  in 
  

   embrace 
  in 
  the 
  end 
  of 
  May 
  near 
  Salzburg 
  and 
  near 
  

   Bordeaux, 
  and 
  spawning 
  in 
  Belgium 
  in 
  June 
  and 
  

   July. 
  Two 
  years 
  ago, 
  around 
  Freiburg 
  in 
  Baden, 
  the 
  

   breeding 
  seemed 
  to 
  be 
  over 
  in 
  the 
  beginning 
  of 
  

   August. 
  On 
  the 
  whole, 
  as 
  observed 
  by 
  Werner, 
  this 
  

   species 
  appears 
  to 
  breed 
  a 
  little 
  later 
  than 
  its 
  con- 
  

   gener 
  ; 
  near 
  Vienna, 
  where 
  the 
  two 
  occur, 
  the 
  season 
  

   has 
  been 
  observed 
  by 
  that 
  authority 
  to 
  begin 
  in 
  the 
  

   first 
  half 
  of 
  May 
  for 
  B. 
  igneus, 
  in 
  the 
  second 
  half 
  of 
  

   the 
  same 
  month 
  for 
  B. 
  pachypns. 
  The 
  eggs 
  are 
  

   usually 
  attached 
  to 
  weeds 
  as 
  in 
  the 
  other 
  species 
  ; 
  

   but 
  as 
  they 
  are 
  sometimes 
  laid 
  in 
  puddles 
  without 
  any 
  

   trace 
  of 
  vegetation, 
  they 
  then 
  simply 
  drop 
  to 
  the 
  

   bottom. 
  The 
  lack 
  of 
  vegetation 
  is 
  no 
  hindrance 
  to 
  

   the 
  development 
  of 
  the 
  larvae, 
  which 
  are 
  mainly 
  car- 
  

   nivorous. 
  Recently 
  transformed 
  young 
  were 
  found 
  

   by 
  Schrank 
  in 
  the 
  last 
  century 
  in 
  the 
  salt 
  water 
  of 
  

   the 
  saline 
  caves 
  of 
  Berchtesgaden, 
  Austria. 
  

  

  These 
  Batrachians 
  hibernate 
  on 
  land 
  in 
  holes 
  or 
  

   under 
  stones. 
  In 
  early 
  spring, 
  in 
  Belgium, 
  I 
  have 
  

   found 
  several 
  specimens 
  together 
  in 
  their 
  winter 
  

   quarters 
  — 
  deep 
  recesses 
  between 
  stones, 
  which 
  they 
  

   shared 
  with 
  Salamandra 
  maculosa. 
  They 
  do 
  not 
  

   appear 
  to 
  emerge 
  before 
  the 
  end 
  of 
  April, 
  when 
  they 
  

   travel 
  considerable 
  distances 
  in 
  search 
  of 
  suitable 
  

   breeding 
  localities, 
  breaking 
  the 
  journey 
  in 
  any 
  small 
  

   temporary 
  puddle 
  they 
  come 
  across. 
  I 
  much 
  doubt
