  HYLI.DJ5. 
  

  

  lateral 
  line 
  on 
  the 
  body; 
  a 
  whitish 
  cross-streak 
  above 
  

   the 
  vent; 
  a 
  whitish 
  or 
  pale 
  golden 
  line 
  along 
  the 
  

   inner 
  edge 
  of 
  the 
  tibia 
  and 
  the 
  outer 
  edge 
  of 
  the 
  

   tarsus, 
  metatarsus, 
  and 
  fifth 
  toe 
  ; 
  back 
  of 
  the 
  thighs 
  

   often 
  yellow 
  or 
  pale 
  orange, 
  uniform 
  or 
  speckled 
  with 
  

   brown. 
  This 
  form 
  inhabits 
  the 
  south 
  of 
  France, 
  

   Italy, 
  the 
  Pyrenean 
  peninsula, 
  the 
  Balearic 
  Islands, 
  

   North-west 
  Africa, 
  Madeira, 
  and 
  the 
  Canary 
  Islands. 
  

   A 
  further 
  variety 
  (immaculata, 
  Bttgr.*) 
  has 
  been 
  

   described 
  from 
  China, 
  but 
  as 
  it 
  lacks 
  the 
  web 
  between 
  

   the 
  fingers 
  it 
  cannot 
  be 
  united, 
  with 
  H. 
  arborea. 
  Var. 
  

   orie?italis, 
  Beclr., 
  from 
  Russia, 
  and 
  var. 
  molleri, 
  Bedr., 
  

   from 
  Portugal, 
  I 
  would 
  regard 
  as 
  not 
  sufficiently 
  

   distinguished 
  from 
  the 
  typical 
  form; 
  and 
  the 
  var. 
  

   intermedia, 
  Blgr., 
  may 
  be 
  merely 
  a 
  mongrel. 
  I 
  shall 
  

   therefore 
  limit 
  myself 
  to 
  remarks 
  on 
  the 
  value 
  of 
  the 
  

   characters 
  of 
  the 
  vars. 
  savigmji 
  and 
  meridionalis, 
  

   which 
  have 
  been 
  regarded 
  by 
  some 
  authors 
  as 
  distinct 
  

   species. 
  But 
  before 
  doing 
  this 
  it 
  is 
  desirable 
  to 
  give 
  

   detailed 
  measurements 
  of 
  specimens 
  of 
  the 
  typical 
  

   form 
  and 
  the 
  two 
  principal 
  varieties.
