  arms 
  redder, 
  tail 
  dirty 
  brown. 
  The 
  pelage 
  is 
  thick 
  and 
  curly. 
  Seem- 
  

   ingly 
  the 
  skin 
  was 
  not 
  properly 
  relaxed 
  for 
  mounting, 
  and 
  as 
  a 
  result 
  

   the 
  hair 
  assumed 
  curls 
  and 
  whorls 
  that 
  may 
  have 
  formed 
  in 
  the 
  dry 
  

   twisted 
  and 
  unprepared 
  skin. 
  The 
  specimen 
  is 
  clearly 
  that 
  of 
  an 
  

   "untufted" 
  Cebus, 
  more 
  probably 
  of 
  the 
  albifrons 
  than 
  of 
  the 
  nigri- 
  

   vittatus 
  group. 
  It 
  was 
  said 
  to 
  have 
  originated 
  in 
  the 
  Guianas, 
  but 
  

   the 
  specimen 
  itself 
  is 
  without 
  locality 
  data. 
  Geolfroy's 
  synonymies 
  

   make 
  barbatus 
  a 
  composite 
  species, 
  since 
  he 
  cited 
  the 
  sajou 
  gris 
  of 
  

   Buffon 
  and 
  Daubenton,, 
  a 
  "tufted" 
  Cebus 
  {C. 
  apella),^ 
  and 
  the 
  "Sai 
  

   Var. 
  A. 
  Aud., 
  Jam. 
  5, 
  sec. 
  2, 
  fig. 
  6." 
  The 
  cited 
  figure 
  6 
  belongs 
  to 
  

   the 
  Sai 
  variete 
  B 
  of 
  Audebert, 
  not 
  variete 
  A 
  as 
  given 
  by 
  Geoffroy. 
  

   Cabrera 
  (1917a, 
  p. 
  227) 
  identified 
  the 
  sai 
  variete 
  B 
  of 
  Audebert 
  as 
  

   C. 
  olivaceus, 
  here 
  treated 
  as 
  a 
  race 
  of 
  C. 
  nigrivittatus. 
  Desmarest 
  

   (1820, 
  p. 
  81) 
  recognized 
  the 
  composite 
  nature 
  of 
  Geoffrey's 
  descrip- 
  

   tion 
  and 
  named 
  the 
  sajou 
  gris, 
  Cebus 
  griseus. 
  He 
  then 
  listed 
  the 
  

   restricted 
  C. 
  barbatus 
  of 
  Geoffroy 
  with 
  the 
  reference 
  to 
  Audebert's 
  

   figure 
  6, 
  as 
  a 
  distinct 
  species. 
  This 
  procedure 
  appears 
  justifiable, 
  as 
  

   neither 
  the 
  type 
  specimen 
  of 
  barbatus 
  nor 
  the 
  cited 
  figure 
  of 
  Audebert 
  

   is 
  the 
  same 
  as 
  the 
  sajou 
  gris 
  of 
  Buffon 
  and 
  Daubenton. 
  Unfortunately, 
  

   Desmarest's 
  description 
  is 
  also 
  composite. 
  In 
  addition 
  to 
  the 
  sajou 
  

   gris, 
  he 
  cited 
  the 
  sajou 
  male 
  of 
  Cuvier 
  (1819, 
  pi.). 
  This 
  last 
  is 
  an 
  

   "untufted" 
  Cebus 
  representing 
  an 
  extremely 
  pale 
  variety 
  of 
  C. 
  nigri- 
  

   vittatus. 
  The 
  embroiled 
  nomenclature 
  of 
  the 
  above 
  forms 
  may 
  be 
  

   set 
  forth 
  more 
  clearly 
  in 
  the 
  following 
  summary: 
  

  

  1. 
  The 
  lectotype 
  of 
  C. 
  barbatus 
  Geoffroy, 
  perhaps 
  from 
  the 
  Guianas, 
  

   is 
  an 
  "un 
  tufted" 
  Cebus 
  but 
  otherwise 
  unidentifiable. 
  Its 
  name 
  is 
  

   preoccupied 
  by 
  C. 
  barbatus 
  Humboldt. 
  

  

  2. 
  Humboldt 
  cited 
  only 
  the 
  sajou 
  gris 
  as 
  a 
  basis 
  for 
  the 
  name 
  bar- 
  

   batus. 
  Consequently, 
  C. 
  griseus 
  Desmarest, 
  based 
  primarily 
  on 
  the 
  

   sajou 
  gris 
  of 
  Buffon 
  and 
  Daubenton, 
  is 
  an 
  absolute 
  synonym 
  of 
  bar- 
  

   batus 
  Humboldt 
  and 
  both 
  are 
  equal 
  to 
  Cebus 
  apella 
  Linnaeus. 
  No 
  

   locality 
  for 
  either 
  barbatus 
  or 
  griseus 
  was 
  given. 
  

  

  3. 
  If 
  Kerr's 
  names 
  are 
  valid, 
  as 
  they 
  appear 
  to 
  be, 
  then 
  both 
  bar- 
  

   batus 
  Humboldt 
  and 
  griseus 
  Desmarest 
  are 
  antedated 
  by 
  Simia 
  

   (Sapajus) 
  trepidus 
  fulvus, 
  based 
  strictly 
  on 
  the 
  sajou 
  gris. 
  Allen 
  

   (1895, 
  p. 
  186) 
  has 
  shown 
  fulvus 
  Kerr 
  to 
  be 
  a 
  synonym 
  of 
  C. 
  apella. 
  

  

  Cebus 
  flavus 
  E. 
  Geoffroy 
  (1812, 
  p. 
  111). 
  This 
  is 
  probably 
  an 
  

   "untufted" 
  Cebus. 
  Beyond 
  this, 
  Jlavus 
  is 
  not 
  certainly 
  identifiable. 
  

   The 
  monkey, 
  listed 
  by 
  Eode 
  (1938, 
  p. 
  231) 
  as 
  "Holotype," 
  No. 
  562 
  

  

  • 
  The 
  original 
  figure 
  of 
  the 
  sajou 
  gris 
  (1767, 
  pi. 
  V) 
  is 
  hardly 
  identifiable. 
  The 
  description 
  (p. 
  50), 
  however, 
  

   states 
  clearly 
  one 
  external 
  character 
  of 
  the 
  "tufted," 
  or 
  apella 
  group, 
  which 
  is 
  diagnostic, 
  the 
  black 
  tipped 
  

   hairs 
  that 
  "fermoit 
  une 
  bande 
  sur 
  chaque 
  joue." 
  In 
  Buffon 
  and 
  Daubenton 
  the 
  sajous 
  are 
  equivalent 
  to 
  

   the 
  "tufted" 
  Cebus, 
  the 
  sais 
  to 
  the 
  "untufted." 
  Cabrera 
  (1917a, 
  p. 
  231) 
  also 
  quoted 
  the 
  description, 
  but 
  at 
  

   greater 
  length, 
  to 
  prove 
  that 
  the 
  sajou 
  gris 
  cannot 
  be 
  identified 
  with 
  albifrons, 
  olivaceus, 
  or 
  nigriviltatits, 
  

   Latreille 
  (in 
  Buffon, 
  Hist. 
  Nat., 
  Sonnini 
  ed., 
  vol. 
  36, 
  p. 
  280, 
  1804) 
  saw 
  the 
  types 
  of 
  Buffon's 
  sajou 
  gris 
  and 
  

   sajou 
  bTun 
  "vivans 
  & 
  la 
  mfenagerie 
  du 
  mus6um 
  irancais." 
  He 
  assigned 
  both 
  to 
  his 
  CalHlhrix 
  apella 
  (^Simta 
  

   apella 
  Linnaeus).
