  relatively 
  even. 
  The 
  inner 
  surface 
  is 
  stamped 
  with 
  a 
  chain 
  of 
  im- 
  

   pressions 
  overhung 
  by 
  a 
  projecting 
  ledge, 
  marking 
  the 
  attachment 
  

   of 
  the 
  sacrum. 
  

  

  The 
  elongated 
  figure 
  of 
  the 
  ilium 
  places 
  the 
  animal 
  represented 
  by 
  

   it 
  beyond 
  doubt 
  in 
  the 
  family 
  Iguanodontidse. 
  In 
  the 
  comparative 
  

   shortness 
  and 
  stoutness 
  of 
  the 
  preacetabular 
  process 
  and 
  the 
  more 
  

   tapering 
  form 
  of 
  the 
  postacetabular 
  front 
  of 
  the 
  bone, 
  this 
  ilium 
  

   certainly 
  differs 
  from 
  that 
  of 
  /. 
  Mantelli, 
  regarding 
  as 
  the 
  type 
  of 
  

   this 
  latter 
  the 
  ilia 
  preserved 
  in 
  the 
  large 
  slab 
  from 
  Bensted 
  quarry 
  

   in 
  the 
  British 
  Museum, 
  which 
  originally 
  formed 
  part 
  of 
  the 
  collec- 
  

   tion 
  of 
  the 
  late 
  Dr. 
  G. 
  A. 
  Mantell. 
  

  

  Femur 
  (PL 
  IY. 
  fig. 
  2). 
  — 
  The 
  proximal 
  end 
  of 
  this 
  gigantic 
  bone 
  is 
  

   crushed 
  ; 
  but 
  the 
  distal 
  end 
  is 
  fairly 
  preserved, 
  The 
  present 
  length 
  of 
  

   the 
  femur 
  is 
  92 
  centim. 
  (3 
  feet); 
  when 
  entire 
  the 
  length 
  was 
  probably 
  

   not 
  less 
  than 
  108 
  centim. 
  (42| 
  in.). 
  The 
  distal 
  end 
  has 
  the 
  usual 
  

   condylar 
  division; 
  the 
  condyles 
  project 
  strongly 
  backwards. 
  The 
  

   anterior 
  intercondylar 
  groove 
  (ic) 
  is 
  characteristically 
  deep 
  and 
  

   narrow. 
  The 
  shaft 
  has 
  an 
  apparent 
  twist, 
  owing 
  to 
  a 
  change 
  in 
  the 
  

   direction 
  of 
  its 
  surface 
  ; 
  that 
  which 
  at 
  the 
  proximal 
  end 
  is 
  external 
  

   becomes 
  towards 
  the 
  distal 
  end 
  anterior 
  or 
  dorsal. 
  The 
  inner 
  tro- 
  

   chanter 
  (i 
  t) 
  is 
  strongly 
  marked. 
  The 
  girth 
  of 
  the 
  femur 
  at 
  the 
  distal 
  

   condylar 
  end 
  is 
  82 
  centim. 
  (32^ 
  in.), 
  and 
  the 
  breadth 
  across 
  the 
  con- 
  

   dyles 
  is 
  32 
  centim. 
  (12|» 
  in.). 
  The 
  girth 
  of 
  the 
  shaft 
  just 
  above 
  the 
  

   condyles 
  is 
  69 
  centim. 
  (27 
  in.), 
  and 
  that 
  immediately 
  above 
  the 
  

   inner 
  trochanter 
  is 
  64 
  centim. 
  (25-A- 
  in.). 
  Towards 
  the 
  proximal 
  

   end 
  the 
  girth 
  again 
  increases. 
  These 
  measurements 
  will 
  furnish 
  

   an 
  idea 
  of 
  the 
  size 
  and 
  proportions 
  of 
  this 
  thigh-bone, 
  which 
  is 
  one 
  

   of 
  the 
  very 
  largest 
  I 
  have 
  yet 
  seen. 
  

  

  Tibia 
  (PI. 
  IY. 
  fig. 
  3). 
  — 
  I 
  found 
  this 
  lying 
  athwart 
  the 
  thigh-bone. 
  

   Both 
  its 
  ends 
  are 
  much 
  crushed 
  and 
  mutilated. 
  The 
  precnemial 
  crest 
  

   was 
  very 
  large 
  ; 
  it 
  was 
  so 
  shattered 
  that 
  in 
  spite 
  of 
  great 
  care 
  it 
  fell 
  

   to 
  pieces 
  as 
  we 
  lifted 
  the 
  bone 
  out 
  of 
  the 
  cliff, 
  and 
  it 
  could 
  not 
  be 
  

   restored. 
  The 
  shaft 
  has 
  the 
  usual 
  subprismatic 
  figure 
  in 
  its 
  central 
  

   part, 
  and 
  it 
  expands 
  towards 
  its 
  articular 
  extremities. 
  The 
  breadth 
  

   of 
  the 
  lower 
  end, 
  approximately 
  inferred 
  from 
  that 
  of 
  the 
  composite 
  

   articular 
  surface 
  formed 
  by 
  the 
  proximal 
  end 
  of 
  the 
  metatarsal 
  bones, 
  

   will 
  not 
  have 
  been 
  less 
  than 
  35 
  centim. 
  (nearly 
  14 
  in.) 
  ; 
  the 
  proxi- 
  

   mal 
  end 
  still 
  shows, 
  obscurely, 
  a 
  subdivision 
  into 
  two 
  parts 
  corre- 
  

   sponding 
  to 
  the 
  femoral 
  condyles. 
  The 
  length 
  of 
  the 
  tibia 
  in 
  the 
  

   present 
  mutilated 
  state 
  is 
  92 
  centim. 
  (36 
  in.) 
  ; 
  102 
  centim. 
  (40 
  in.), 
  

   somewhat 
  less 
  than 
  that 
  of 
  the 
  femur, 
  will 
  not, 
  I 
  think, 
  be 
  an 
  

   unfair 
  estimate 
  of 
  its 
  length 
  when 
  perfect. 
  The 
  girth 
  at 
  the 
  middle 
  

   of 
  the 
  shaft 
  is 
  45 
  centim. 
  (17 
  t 
  7 
  q 
  in.). 
  

  

  Fibula 
  (PL 
  IY. 
  fig. 
  4). 
  — 
  This 
  bone, 
  nearly 
  as 
  long 
  as 
  the 
  tibia 
  when 
  

   perfect, 
  has 
  been 
  shortened 
  to 
  85 
  centim. 
  (32| 
  in.) 
  by 
  mutilation 
  of 
  

   its 
  distal 
  end. 
  The 
  proximal 
  end 
  is 
  broad 
  and 
  flattened 
  ; 
  the 
  tibial 
  

   aspect 
  is 
  slightly 
  hollowed. 
  The 
  shaft 
  is 
  relatively 
  slender; 
  its 
  

   figure 
  is 
  subprismatic. 
  (The 
  os 
  calcis 
  and 
  astragalus 
  were 
  not 
  re- 
  

   covered.) 
  

  

  Foot 
  (PL 
  IY. 
  fig. 
  5). 
  — 
  The 
  bones 
  of 
  the 
  left 
  metatarsus, 
  cemented 
  

   together 
  by 
  rock, 
  preserve 
  their 
  natural 
  relations 
  but 
  slightly 
  disor-
