  to 
  say, 
  slightly 
  sand-polished. 
  It 
  was 
  obtained 
  by 
  Mr. 
  Moir 
  from 
  Bolton 
  

   and 
  Laughlin's 
  great 
  pit 
  at 
  Whitton, 
  Ipswich. 
  It 
  is 
  less 
  sharp 
  in 
  its 
  edges 
  

   and 
  more 
  "polished" 
  than 
  is 
  the 
  Sturge 
  Icklingham 
  specimen 
  just 
  described. 
  

   It 
  has 
  also 
  special 
  importance 
  as 
  coming 
  from 
  the 
  Mid-Glacial 
  Gravel. 
  Other 
  

   implements 
  have 
  been 
  described 
  by 
  Mr. 
  Moir 
  from 
  this 
  locally 
  well-developed 
  

   gravel, 
  as 
  well 
  as 
  the 
  present 
  specimen.

  The, 
  " 
  Capitan-Oise 
  " 
  and

  Uncinates. 
  

  

  The 
  remarkable 
  coincidence 
  in 
  the 
  sculpture 
  of 
  these 
  two 
  implements 
  

   renders 
  it 
  desirable 
  to 
  describe 
  them 
  together. 
  The 
  Capitan-Oise 
  specimen 
  

   (figs. 
  6, 
  8, 
  10, 
  and 
  12) 
  was 
  sent 
  to 
  me 
  by 
  Prof. 
  Capitan, 
  of 
  Paris, 
  in 
  1915, 
  as 
  

   being, 
  in 
  his 
  opinion, 
  an 
  implement 
  of 
  the 
  rostro-carinate 
  type. 
  He 
  writes 
  : 
  

   " 
  II 
  provient 
  des 
  graviers 
  du 
  fond 
  de 
  la 
  vallee 
  de 
  l'Oise, 
  sans 
  provenance 
  

   precise, 
  mais 
  certainement 
  de 
  la 
  basse 
  vallee. 
  Ces 
  graviers 
  debutent 
  (comme 
  

   faune 
  et 
  industrie) 
  au 
  Chelleen 
  et 
  vont 
  jusqu'au 
  Mousterien." 
  

  

  When 
  this 
  specimen 
  reached 
  me, 
  I 
  was 
  already 
  in 
  possession 
  of 
  that 
  found 
  

   in 
  the 
  gravel 
  at 
  Burnham 
  Beeches 
  (Thames 
  valley) 
  by 
  Dr. 
  Powell, 
  and 
  the 
  

   close 
  similarity 
  of 
  the 
  two 
  specimens 
  was 
  at 
  once 
  obvious. 
  In 
  both, 
  the 
  

   anterior 
  region 
  or 
  " 
  rostrum 
  " 
  has 
  a 
  somewhat 
  " 
  hooked 
  " 
  or 
  claw-like 
  

   appearance, 
  which 
  may 
  be 
  described 
  as 
  " 
  uncinate." 
  This 
  shape 
  of 
  rostrum 
  

   was 
  already 
  known 
  to 
  me 
  in 
  some 
  other 
  rostro-carinates, 
  for 
  instance, 
  in 
  the 
  

   " 
  Moir 
  Ipswich 
  uncinate," 
  drawn 
  in 
  figs. 
  6 
  and 
  7 
  of 
  my 
  memoir.* 
  Further, 
  

   both 
  the 
  Oise 
  and 
  the 
  Burnham 
  Beeches 
  specimens 
  present 
  none 
  of 
  the 
  

   original 
  cortex, 
  but 
  are 
  flaked 
  all 
  over, 
  excepting 
  a 
  small 
  area 
  of 
  the 
  Oise 
  

   specimen, 
  shown 
  in 
  fig. 
  8, 
  in 
  deep 
  shadow 
  below 
  the 
  line 
  llv. 
  (which 
  I 
  

   identify 
  as 
  corresponding 
  to 
  the 
  left 
  latero-ventral 
  margin 
  of 
  the 
  ideal 
  type, 
  

   fig. 
  1), 
  and 
  they 
  are 
  iron-stained 
  all 
  over 
  — 
  the 
  Oise 
  specimen 
  more 
  deeply 
  

   than 
  the 
  other. 
  

  

  But 
  the 
  two 
  most 
  important 
  features 
  shown 
  by 
  the 
  Oise 
  and 
  Burnham 
  

   Beeches 
  specimens 
  are, 
  first, 
  the 
  very 
  large 
  and 
  flat 
  dorsal 
  platform 
  or 
  plane, 
  

   marked 
  D.P. 
  in 
  the 
  figures, 
  showing 
  in 
  each 
  case 
  the 
  curved 
  ridge-like 
  

   ripple 
  marks 
  produced 
  by 
  the 
  single 
  blow 
  by 
  which 
  it 
  was 
  formed, 
  and 
  

   second, 
  the 
  apparent 
  absence 
  of 
  anything 
  like 
  the 
  great 
  " 
  ventral 
  plane 
  " 
  of 
  

   the 
  ideal 
  type, 
  which 
  in 
  most 
  rostro-carinates 
  is 
  a 
  very 
  obvious 
  and 
  

   important 
  feature 
  of 
  their 
  architecture. 
  In 
  both 
  specimens 
  a 
  keel-like 
  

   ridge 
  (rlv. 
  in 
  the 
  figures) 
  forms 
  the 
  ventral 
  boundary 
  of 
  the 
  rostral 
  region 
  

   of 
  the 
  implement, 
  though 
  the 
  posterior 
  half 
  is 
  broad 
  and 
  butt-like.
