  north-east 
  and 
  the 
  central 
  plateau.* 
  It 
  also 
  occurs 
  in 
  

   Jersey. 
  It 
  is 
  rare 
  and 
  very 
  local 
  in 
  Germany, 
  the 
  

   localities 
  whence 
  it 
  has 
  been 
  reported 
  being 
  Strass- 
  

   burg, 
  Linz 
  on 
  the 
  Rhine, 
  the 
  Kaisers 
  tuhl 
  between 
  

   Freiburg

  Rothenburg 
  on 
  tbe 
  Tauber, 
  

   Wiirzburg 
  and 
  Traunstein 
  in 
  Bavaria, 
  and 
  about 
  the 
  

   Zobten, 
  south 
  of 
  Breslau, 
  in 
  Silesia. 
  f 
  In 
  Switzer- 
  

   land 
  it 
  is 
  known 
  from 
  the 
  cantons 
  Geneva, 
  Vaud, 
  

   Bern, 
  Zurich, 
  Valais. 
  and 
  Tessin 
  ; 
  in 
  the 
  Austro- 
  

   Hungarian 
  Empire 
  from 
  Bohemia, 
  Lower 
  Austria, 
  

   Styria, 
  the 
  Tyrol, 
  Illyria, 
  Croatia, 
  Dalmatia, 
  Hungary, 
  

   and 
  Transylvania. 
  It 
  appears 
  to 
  be 
  pretty 
  generally 
  

   distributed 
  in 
  Italy, 
  and 
  is 
  on 
  record 
  from 
  Modica, 
  

   Sicily. 
  It 
  is 
  further 
  known 
  from 
  Bosnia, 
  Albania, 
  

   and 
  Greece. 
  The 
  only 
  localities 
  in 
  Asia 
  whence 
  R. 
  

   agilis 
  has 
  been 
  recorded 
  are 
  Lenkoran, 
  on 
  the 
  south- 
  

   western 
  coast 
  of 
  the 
  Caspian 
  Sea 
  (Boettger), 
  Suchum 
  

   Kale, 
  Transcaspia, 
  and 
  Konkur 
  Valley,

  Hi 
  

   (Beclriaga), 
  the 
  two 
  latter 
  requiring 
  confirmation. 
  

   Strauch 
  has 
  also 
  referred 
  some 
  specimens 
  obtained 
  by 
  

   Przewalski 
  in 
  the 
  Chinese 
  province 
  Ordos 
  to 
  what 
  

   he 
  called 
  the 
  " 
  agilis 
  " 
  form 
  of 
  R. 
  temporaria, 
  but 
  these 
  

   will 
  no 
  doubt 
  prove 
  to 
  belong 
  to 
  R.japonica,& 
  species 
  

   which 
  bears 
  great 
  resemblance 
  to 
  R. 
  agilis. 
  

  

  Rana 
  agilis 
  is, 
  on 
  the 
  whole, 
  more 
  a 
  form 
  of 
  the 
  

   plain, 
  being 
  replaced 
  in 
  the 
  mountains 
  by 
  R. 
  tempo- 
  

   raria 
  ; 
  it 
  is, 
  however, 
  known 
  to 
  reach 
  an 
  altitude 
  of 
  

   4200 
  feet 
  in 
  the 
  Alps 
  of 
  Switzerland, 
  and 
  to 
  extend 
  

   pretty 
  high 
  up 
  in 
  the 
  Tyrol 
  and 
  in 
  Transylvania, 
  as 
  

   well 
  as 
  in 
  the 
  Apennines.

  Dealing 
  with 
  the 
  mucilaginous 
  capsules 
  of 
  frog 
  ova, 
  R. 
  Florentin 
  

   ('Bull. 
  Sci-Franee 
  Belg.,' 
  xx, 
  1897, 
  p. 
  142), 
  mentions 
  having 
  made 
  ex- 
  

   periments 
  at 
  Nancy 
  on 
  Rana 
  agilis, 
  Thom. 
  As 
  this 
  statement 
  might 
  

   result 
  in 
  French 
  Lorraine 
  being 
  erroneously 
  or 
  prematurely 
  added 
  to 
  

   the 
  habitat 
  of 
  this 
  species, 
  I 
  may 
  point 
  out 
  that 
  an 
  error 
  of 
  identifica- 
  

   tion 
  has 
  been 
  made, 
  since 
  had 
  the 
  author 
  really 
  seen 
  eggs 
  of 
  R. 
  agilis 
  

   he 
  would 
  not 
  have 
  attributed 
  to 
  frog 
  spawn 
  generally 
  the 
  floating 
  power 
  

   which 
  is 
  possessed 
  by 
  that 
  of 
  R. 
  tcmporaria 
  alone 
  among 
  European 
  

   Batrachians. 
  

  

  f 
  I 
  have 
  examined 
  a 
  specimen 
  from 
  this 
  locality.
