  and 
  a 
  somewhat 
  more 
  slender 
  habit, 
  resulting 
  in 
  a 
  

   certain 
  resemblance 
  to 
  Bana 
  agilis, 
  with 
  which 
  it 
  also 
  

   often 
  agrees 
  in 
  the 
  absence 
  of 
  any 
  but 
  small 
  red 
  spots 
  

   on 
  the 
  belly. 
  

  

  The 
  var. 
  bosniensis, 
  recently 
  established 
  by 
  Werner 
  

   {' 
  Rept. 
  Amph. 
  Oesterr.,' 
  p. 
  92) 
  on 
  a 
  single 
  male 
  

   specimen 
  from 
  Travnik, 
  Bosnia, 
  is, 
  in 
  my 
  opinion, 
  not 
  

   entitled 
  to 
  stand. 
  Thanks 
  to 
  Dr. 
  Werner's 
  courtesy, 
  

   I 
  have 
  examined 
  the 
  type, 
  and 
  find 
  the 
  pelvis 
  to 
  

   be 
  broken, 
  which 
  accounts 
  for 
  the 
  shortness 
  of 
  the 
  

   body; 
  hence 
  the 
  tibio-tarsal 
  articulation 
  of 
  the 
  hind 
  

   limb 
  reaches 
  a 
  little 
  beyond 
  the 
  tip 
  of 
  the 
  snout. 
  The 
  

   specimen 
  measures 
  71 
  mm. 
  from 
  snout 
  to 
  vent; 
  fore 
  

   limb 
  49 
  mm. 
  ; 
  tibia 
  42 
  mm. 
  

  

  The 
  var. 
  longipes 
  of 
  F. 
  Midler 
  — 
  of 
  which 
  the 
  type, 
  

   from 
  Oberweiler, 
  between 
  Mullheim 
  and 
  Badenweiler, 
  

   Baden, 
  has 
  been 
  entrusted 
  to 
  me 
  by 
  Mr. 
  Schenkel, 
  

   the 
  curator 
  of 
  the 
  Basle 
  Museum 
  — 
  is 
  based 
  on 
  a 
  

   somewhat 
  long-legged 
  individual 
  of 
  the 
  common 
  frog, 
  

   in 
  which 
  the 
  tibio-tarsal 
  articulation 
  reaches 
  exactly 
  

   the 
  tip 
  of 
  the 
  snout, 
  — 
  not 
  beyond, 
  as 
  stated 
  in 
  the 
  

   original 
  description. 
  The 
  specimen, 
  a 
  female, 
  measures 
  

   55 
  mm. 
  from 
  snout 
  to 
  vent; 
  fore 
  limb 
  36 
  mm.; 
  tibia 
  

   30 
  mm. 
  C. 
  Koch's 
  var. 
  gracilis 
  is 
  no 
  doubt 
  founded 
  

   on 
  similar 
  examples, 
  which 
  seem 
  to 
  predominate 
  on 
  

   the 
  southern 
  slopes 
  of 
  the 
  Alps, 
  and 
  have 
  been 
  de- 
  

   scribed 
  by 
  Heron-B,oyer 
  as 
  a 
  distinct 
  sub-species, 
  Bana 
  

   fusca 
  honnorati, 
  from 
  the 
  Basses-Alpes. 
  The 
  larval 
  

   characters 
  adduced 
  in 
  support 
  of 
  the 
  establishment 
  of 
  

   the 
  latter 
  form 
  have 
  since 
  proved 
  to 
  be 
  as 
  unreliable 
  

   as 
  those 
  derived 
  from 
  the 
  perfect 
  animal.
