  Although 
  closely 
  allied 
  to 
  the 
  preceding, 
  with 
  which 
  

   it 
  has 
  long 
  been 
  confounded, 
  this 
  species 
  is 
  easily 
  

   distinguished 
  by 
  several 
  important 
  characters. 
  

  

  The 
  general 
  habitus 
  is 
  stouter 
  still. 
  Head 
  con- 
  

   stantly 
  broader 
  than 
  long 
  ; 
  snout 
  more 
  broadly 
  

   rounded, 
  as 
  long 
  as 
  or 
  slightly 
  shorter 
  than 
  the 
  

   diameter 
  of 
  the 
  orbit 
  ; 
  eye 
  rather 
  larger 
  ; 
  nostril 
  

   equally 
  distant 
  from 
  the 
  end 
  of 
  the 
  snout 
  and 
  the 
  

   eye, 
  or 
  slightly 
  nearer 
  the 
  latter. 
  In 
  some 
  males 
  the 
  

   tarso-metatarsal 
  articulation 
  reaches 
  a 
  little 
  beyond 
  

   the 
  eye. 
  Tibia 
  as 
  long 
  as 
  the 
  femur, 
  and 
  as 
  long 
  as 
  

   or 
  slightly 
  longer 
  than 
  the 
  foot 
  ; 
  the 
  heels 
  usually 
  

   meet 
  when 
  the 
  legs 
  are 
  folded 
  against 
  the 
  thighs. 
  

   The 
  foot 
  is 
  usually 
  rather 
  swollen, 
  the 
  digits 
  shorter, 
  

   and 
  the 
  web 
  fuller, 
  often 
  w^ith 
  rectilinear 
  border 
  in 
  

   the 
  males. 
  Warts 
  on 
  the 
  upper 
  surfaces 
  usually 
  more 
  

   prominent 
  and 
  more 
  crowded, 
  not 
  forming 
  sym- 
  

   metrical 
  chains 
  ; 
  parotoid 
  gland 
  very 
  rarely 
  distinct.

  Piece 
  of 
  dorsal 
  skin 
  of 
  male 
  ( 
  X 
  8). 
  

  

  The 
  black 
  horny 
  excrescences 
  on 
  the 
  warts 
  con- 
  

   sisting 
  in 
  the 
  males 
  of 
  regular 
  spines, 
  distinguishable 
  

   with 
  the 
  aid 
  of 
  an 
  ordinary 
  hand 
  lens, 
  surrounded 
  

   with 
  very 
  small 
  points 
  {Pig.

  female 
  specimens,
