  On 
  some 
  Rostro-carinate 
  Flint 
  Implements 
  and 
  Allied 
  Forms. 
  

   By 
  Sir 
  E. 
  Ray 
  Lankester, 
  K.C.B., 
  F.B.S. 
  

  

  (Received 
  May 
  31, 
  1920.) 
  

  

  The 
  specific 
  type 
  of 
  flint 
  implement 
  which 
  was 
  discovered 
  by 
  Mr. 
  Reid 
  

   Moir, 
  of 
  Ipswich, 
  in 
  1909, 
  and 
  described 
  by 
  me* 
  as 
  the 
  " 
  rostro-carinate 
  " 
  

   type, 
  has 
  been 
  found 
  and 
  recognised 
  by 
  various 
  observers 
  since 
  that 
  date. 
  

   The 
  importance 
  of 
  these 
  implements 
  arises 
  from 
  two 
  facts. 
  The 
  first 
  is 
  that 
  

   they 
  exhibit 
  a 
  design, 
  or 
  " 
  sculptural 
  form," 
  distinct 
  from 
  that 
  of 
  the 
  . 
  

   previously 
  known 
  palaeolithic 
  flint 
  implements. 
  They 
  do 
  not 
  belong 
  to 
  the 
  

   platessiform 
  tongue-shapecl 
  Chellean 
  and 
  Acheuillian 
  types, 
  nor 
  to 
  the 
  

   amygdaloid 
  somewhat 
  smaller 
  type 
  of 
  the 
  same 
  age. 
  They 
  cannot 
  be 
  grouped 
  

   with 
  the 
  Moustierian 
  pointed 
  flakes 
  and 
  the 
  numerous 
  scrapers, 
  knives 
  and 
  

   borers 
  of 
  various 
  Palaeolithic 
  ages 
  ; 
  nor 
  can 
  they 
  be 
  referred 
  to 
  any 
  recognised 
  

   Neolithic 
  type 
  of 
  implement. 
  

  

  The 
  second 
  fact 
  is 
  that 
  several 
  specimens 
  of 
  this 
  novel 
  type 
  — 
  the 
  rostro- 
  

   carinate 
  — 
  have 
  been 
  found 
  in 
  the 
  detritus-bed 
  (bone-bed) 
  of 
  Suffolk, 
  underlying 
  

   the 
  Red 
  Crag, 
  and 
  in 
  the 
  remarkable 
  " 
  stone-bed 
  " 
  or 
  " 
  flint-bed 
  " 
  underlying 
  

   the 
  Norwich 
  Crag 
  in 
  Norfolk. 
  In 
  those 
  deposits 
  flint 
  implements 
  of 
  the 
  large 
  

   types 
  familiar 
  in 
  the 
  terrace 
  gravels 
  of 
  our 
  river 
  valleys 
  are 
  unknown. 
  

  

  Many 
  " 
  rostro-carinates 
  " 
  of 
  well-defined 
  character 
  have, 
  since 
  my 
  original 
  

   description 
  of 
  the 
  type, 
  been 
  found, 
  some 
  in 
  deposits 
  of 
  later 
  date 
  than 
  the 
  

   sub-Crag 
  detritus-bed 
  of 
  Suffolk 
  and 
  the 
  sub-Crag 
  stone-bed 
  of 
  the 
  Norwich 
  

   area, 
  others 
  actually 
  in 
  the 
  detritus-bed 
  and 
  stone-bed. 
  Mr. 
  Reid 
  Moir 
  has 
  

   obtained 
  typical 
  specimens 
  from 
  the 
  Middle 
  Glacial 
  Gravel 
  and 
  from 
  the 
  

   Chalky 
  Boulder 
  Clay 
  near 
  Ipswich. 
  Prof. 
  Marr 
  has 
  found 
  one 
  in 
  a 
  gravel 
  of 
  

   the 
  Chellean 
  aget 
  near 
  Cambridge. 
  Several 
  have 
  been 
  found 
  in 
  a 
  remarkable 
  

   deposit, 
  described 
  as 
  " 
  a 
  raised 
  beach," 
  at 
  the 
  Island 
  MacGee, 
  near 
  Larne 
  

   (Belfast), 
  of 
  which 
  I 
  have 
  figured 
  the 
  most 
  remarkable 
  specimen 
  in 
  my 
  

   memoir 
  on 
  the 
  Norwich 
  test 
  specimen.^ 
  Mr. 
  Reid 
  Moir 
  has 
  also 
  recently 
  

   published 
  an 
  account§ 
  of 
  a 
  noteworthy 
  series 
  of 
  specimens 
  from 
  river-

  t 
  Prof. 
  Marr 
  obtained 
  this 
  implement 
  at 
  the 
  Traveller's 
  Best 
  Pit, 
  Huntingdon 
  Eoad, 
  

   Cambridge. 
  He 
  writes 
  that 
  " 
  the 
  gravel 
  there 
  contains 
  only 
  worn 
  Chellean 
  and 
  

   Acheulean 
  implements 
  below, 
  and 
  either 
  latest 
  Acheulean 
  or 
  earliest 
  Le 
  Moustier 
  

   (or 
  both) 
  above. 
  The 
  latest 
  things 
  are 
  not 
  much 
  worn." 
  None 
  of 
  it 
  is 
  pre-Chellean, 
  

   but 
  this 
  does 
  not 
  exclude 
  the 
  possibility 
  of 
  the 
  inclusion 
  of 
  a 
  few 
  pre-Chellean 
  

   derivatives.
