  lateral 
  aspect 
  and 
  right 
  lateral 
  aspect 
  of 
  the 
  Sturge-lcklingham 
  

   rostro-carinate. 
  The 
  close 
  similarity 
  of 
  the 
  outline 
  to 
  that 
  of 
  the 
  similar 
  lateral 
  

   view 
  (whether 
  right 
  or 
  left) 
  of 
  the 
  "Norwich 
  test 
  specimen" 
  should 
  be 
  verified 
  

   by 
  comparing 
  these 
  two 
  figures 
  with 
  the 
  figures 
  of 
  the 
  Norwich 
  specimen 
  on 
  the 
  

   opposite 
  page. 
  The 
  lettering 
  here 
  is 
  the 
  same 
  as 
  in 
  figs. 
  3 
  and 
  4, 
  except 
  cp 
  in 
  fig. 
  5, 
  

   which 
  points 
  to 
  the 
  " 
  centre 
  of 
  percussion 
  " 
  of 
  the 
  blow 
  by 
  which 
  the 
  flaked 
  

   surface 
  e 
  e' 
  was 
  formed. 
  The 
  formation 
  of 
  the 
  concave 
  flaked 
  surface 
  f, 
  fig. 
  5, 
  by 
  a 
  

   blow 
  downward 
  from 
  the 
  dorsal 
  plane, 
  is 
  well 
  shown 
  by 
  its 
  rippling. 
  

  

  Fig. 
  4 
  is 
  from 
  a 
  wash-drawing 
  ; 
  fig. 
  5 
  is 
  a 
  reproduction 
  of 
  a 
  photograph 
  of 
  the 
  

   actual 
  specimen. 
  

  

  readily 
  distinguishable 
  as 
  the 
  " 
  Kendall-Savernake 
  " 
  transitionals 
  I 
  and 
  II, 
  

   the 
  " 
  Allen-Brown-Dawley 
  " 
  transitional, 
  the 
  " 
  Smith- 
  Warren-Hill," 
  the 
  

   " 
  Greenhill-Clapton," 
  the 
  " 
  Moir-Ipswich," 
  and 
  the 
  " 
  Barnes-Axniinster 
  " 
  

   transitionals. 
  

  

  Those 
  specimens 
  of 
  rostro-carinate 
  which 
  are 
  here 
  figured 
  for 
  the 
  first
