  Pairing 
  and 
  oviposition 
  take 
  place 
  on 
  land. 
  The 
  

   male 
  seizes 
  the 
  female 
  round 
  the 
  waist; 
  but 
  during 
  

   impregnation, 
  or 
  when 
  he 
  proceeds 
  to 
  lade 
  himseft' 
  

   with 
  the 
  ova, 
  he 
  clasps 
  her 
  round 
  the 
  head 
  in 
  front 
  of 
  

   the 
  fore 
  limbs. 
  Males 
  are 
  more 
  numerous, 
  and 
  often 
  

   dispute 
  about 
  the 
  females. 
  When 
  he 
  has 
  secured 
  un- 
  

   disturbed 
  possession 
  the 
  male 
  strongly 
  bends 
  the 
  body 
  

   so 
  as 
  to 
  bring 
  his 
  heels 
  close 
  to 
  the 
  cloacal 
  region 
  of 
  

   the 
  female, 
  which 
  he 
  proceeds 
  to 
  lubrify 
  by 
  rapid 
  move- 
  

   ments 
  of 
  the 
  inner 
  toes, 
  at 
  times 
  introduced 
  into 
  the 
  

   cloaca, 
  the 
  two 
  feet 
  working 
  alternately. 
  This 
  sort 
  of 
  

   raking 
  consists 
  of 
  1100 
  to 
  1300 
  strokes 
  for 
  the 
  two 
  

   feet, 
  divided 
  into 
  15 
  to 
  21 
  periods 
  of 
  45 
  to 
  103 
  strokes, 
  

   with 
  intervals 
  of 
  two 
  or 
  three 
  minutes' 
  rest, 
  and 
  lasts 
  

   about 
  twenty-five 
  minutes. 
  Then 
  the 
  movements 
  sud- 
  

   denly 
  stop, 
  the 
  female 
  extends 
  her 
  hind 
  limbs, 
  tightly 
  

   embracing 
  those 
  of 
  the 
  male, 
  Avhich 
  are 
  bent 
  at 
  angles 
  

   at 
  the 
  knees, 
  the 
  tarsi 
  erect 
  and 
  pressed 
  close 
  together 
  ; 
  

   the 
  eggs 
  are 
  suddenly 
  expelled, 
  with 
  noise, 
  as 
  if 
  by 
  ex- 
  

   plosion, 
  and 
  fall 
  into 
  the 
  rhomboidal 
  receptacle 
  formed 
  

   between 
  the 
  pelvic 
  limbs 
  and 
  bounded 
  behind 
  and 
  

   beneath 
  by 
  the 
  tarsi 
  and 
  feet 
  of 
  the 
  male. 
  The 
  yellow 
  

   eggs, 
  as 
  if 
  threaded 
  together 
  by 
  elastic 
  filaments, 
  form 
  

   a 
  large 
  mass, 
  two 
  to 
  four 
  layers 
  of 
  about 
  ten, 
  in 
  this 
  

   receptacle. 
  

  

  The 
  very 
  moment 
  the 
  eggs 
  are 
  emitted 
  the 
  male 
  

   unclasps 
  the 
  waist 
  of 
  the 
  female 
  and 
  shifts 
  his 
  hold 
  to 
  

   the 
  base 
  of 
  the 
  head 
  ; 
  the 
  body 
  then 
  stretched 
  out, 
  

   but 
  the 
  legs 
  remaining 
  in 
  the 
  same 
  position 
  as 
  before, 
  

   fecundation 
  commences; 
  it 
  takes 
  place 
  in 
  two 
  or 
  three 
  

   emissions 
  at 
  short 
  intervals. 
  The 
  seminal 
  fluid 
  is 
  

   much 
  diluted 
  with 
  the 
  contents 
  of 
  the 
  urinary 
  bladder, 
  

   which 
  soaks 
  the 
  envelops 
  of 
  the 
  eggs. 
  An 
  interval 
  

   of 
  ten 
  to 
  fifteen 
  minutes' 
  rest 
  follows 
  before 
  the 
  male 
  

   proceeds 
  to 
  attach 
  the 
  eggs 
  to 
  his 
  legs. 
  This 
  is 
  done 
  

   in 
  the 
  following 
  manner 
  : 
  — 
  Still 
  holding 
  his 
  mate 
  

   round 
  the 
  head, 
  he 
  draws 
  out 
  the 
  legs 
  so 
  as 
  to 
  stretch 
  

   the 
  elastic 
  connections 
  between 
  the 
  eggs 
  sticking 
  to 
  

   his 
  tarsi 
  ; 
  then, 
  folding 
  one 
  of 
  the 
  limbs, 
  bringing 
  the
