  Dalilbom, 
  hypomelas 
  Pucheran, 
  avnellatvs 
  Gray, 
  fallax 
  Schlegel, 
  and 
  

   a 
  number 
  of 
  general 
  references. 
  Elliot 
  had 
  examined 
  whatever 
  types 
  

   existed 
  of 
  the 
  above-named 
  forms. 
  "Untufted" 
  forms 
  included 
  by 
  

   Elliot 
  in 
  the 
  synonymy 
  of 
  apella 
  are 
  nigrivittatus 
  Wagner 
  and 
  olivaceus 
  

   Schombm-gk. 
  Elliot 
  did 
  not 
  see 
  the 
  types 
  of 
  either 
  of 
  these 
  and 
  he 
  

   discussed 
  only 
  the 
  secoad. 
  His 
  interpretation 
  of 
  the 
  original 
  descrip- 
  

   tion 
  of 
  olivaceus 
  led 
  him 
  to 
  believe 
  that 
  it 
  was 
  "tufted" 
  and 
  similar 
  to 
  

   apella 
  and 
  jatuellus, 
  but 
  nearer 
  the 
  first. 
  From 
  the 
  foregoing 
  it 
  is 
  

   evident 
  that 
  what 
  Elliot 
  described 
  as 
  C. 
  apella 
  and 
  the 
  types 
  he 
  actually 
  

   examined 
  and 
  believed 
  to 
  be 
  synonyms 
  of 
  apella 
  are 
  indeed 
  "tufted" 
  

   monkeys 
  and 
  may 
  be 
  designated 
  as 
  Cebus 
  apella. 
  On 
  the 
  other 
  hand 
  

   Elliot 
  erred 
  gravely 
  in 
  assuming 
  that 
  Cehus 
  capucinus 
  of 
  authors 
  (not 
  

   Limiaeus) 
  was 
  equivalent 
  to 
  Cebus 
  apella. 
  These 
  "authors" 
  (discussed 
  

   in 
  the 
  following 
  section) 
  painstakingly 
  differentiated 
  between 
  the 
  

   "tufted" 
  monkey 
  which 
  they 
  identified 
  as 
  C. 
  apella 
  and 
  the 
  brown 
  

   "untufted" 
  monkey 
  which, 
  for 
  lack 
  of 
  any 
  other 
  available 
  name, 
  they 
  

   termed 
  C. 
  capucinus. 
  It 
  should 
  be 
  understood 
  that 
  early 
  authors 
  

   based 
  their 
  identifications 
  mainly 
  on 
  the 
  1766, 
  or 
  twelfth, 
  edition 
  of 
  

   the 
  "Systema 
  Natiu-ae" 
  of 
  Linnaeus 
  and 
  on 
  the 
  thirteenth, 
  or 
  Gmelin 
  

   edition, 
  of 
  the 
  Linnaean 
  work. 
  Since 
  all 
  other 
  true 
  cebids, 
  namely, 
  

   apella, 
  trepidus, 
  Sindfatuellus, 
  of 
  these 
  editions 
  are 
  patently 
  "tufted," 
  

   authors 
  settled 
  upon 
  capucinus 
  (not 
  capucinus, 
  1758) 
  as 
  representing 
  

   the 
  "untufted" 
  form. 
  As 
  some 
  of 
  the 
  specimens 
  upon 
  which 
  these 
  

   determinations 
  were 
  made 
  are 
  still 
  extant, 
  Elliot's 
  opinion 
  regarding 
  

   the 
  identity 
  of 
  capucinus 
  of 
  authors 
  is 
  unadvised 
  and 
  has 
  created 
  

   confusion 
  that 
  wiU 
  long 
  sm'vive 
  in 
  some 
  quarters. 
  

  

  In 
  1917 
  Cabrera 
  published 
  notes 
  on 
  Cebus. 
  These 
  documents 
  

   were 
  at 
  the 
  same 
  time 
  a 
  critical 
  review 
  of 
  Elliot's 
  contributions 
  to 
  the 
  

   same 
  subject 
  and 
  an 
  attempt 
  to 
  organize 
  the 
  components 
  of 
  the 
  genus 
  

   into 
  a 
  natural 
  order. 
  In 
  this 
  Cabrera 
  succeeded 
  in 
  correcting 
  the 
  more 
  

   serious 
  errors 
  into 
  which 
  Elliot 
  had 
  fallen 
  and 
  in 
  offering 
  a 
  soimd 
  

   foundation, 
  the 
  first 
  such, 
  upon 
  which 
  to 
  establish 
  a 
  clear 
  understand- 
  

   ing 
  of 
  the 
  true 
  relationships 
  between 
  the 
  species 
  of 
  Cebus. 
  In 
  his 
  

   paper 
  Cabrera 
  immediately 
  affirmed 
  the 
  "tufted" 
  nature 
  of 
  Cebus 
  

   apella 
  and 
  disengaged 
  from 
  its 
  synonymy 
  the 
  Cebus 
  capucinus 
  of 
  

   authors. 
  For 
  the 
  latter, 
  Cabrera 
  established 
  the 
  pertinency 
  of 
  the 
  

   name 
  Cebus 
  nigrivittatus 
  Wagner. 
  Cabrera's 
  classification 
  of 
  "un- 
  

   tufted" 
  cebids 
  may 
  be 
  summarized 
  as 
  follows:
