  last 
  may 
  be 
  identified 
  as 
  a 
  pale 
  race 
  of 
  nigrivittatus 
  not 
  necessarDy 
  

   olivaceus. 
  Pucheran 
  (1856, 
  p. 
  34), 
  in 
  attempting 
  to 
  identify 
  capucinus 
  

   of 
  authors, 
  not 
  Linnaeus, 
  concluded 
  that 
  it 
  was 
  equivalent 
  to 
  olivaceus. 
  

   He 
  also 
  called 
  attention 
  to 
  the 
  figure 
  of 
  "olivaceus" 
  given 
  by 
  Wagner 
  

   in 
  supplementary 
  volume 
  5 
  (1855, 
  pi. 
  8), 
  which 
  he 
  believed 
  to 
  be 
  the 
  

   same 
  as 
  C. 
  castaneus 
  I. 
  Geoffroy. 
  The 
  figure 
  in 
  question 
  is 
  that 
  of 
  a 
  

   pale 
  representative 
  of 
  nigrivittatus 
  , 
  "angeblich 
  aus 
  Colombien." 
  

   Later, 
  Pucheran 
  (1857, 
  pp. 
  345, 
  352) 
  modified 
  his 
  opinion. 
  He 
  

   thought, 
  instead, 
  that 
  olivaceus 
  and 
  castaneus 
  were 
  the 
  same 
  but 
  dis- 
  

   tinct 
  from 
  capucinus 
  of 
  authors 
  (nigrivittatus) 
  . 
  This 
  reversal 
  appears 
  

   to 
  have 
  been 
  a 
  friendly 
  gesture 
  to 
  Dahlbom, 
  who 
  had 
  already 
  bestowed 
  

   the 
  name 
  pucheranii 
  (q. 
  v.) 
  upon 
  the 
  capucinus 
  of 
  authors. 
  The 
  name 
  

   olivaceus 
  was 
  published 
  in 
  the 
  same 
  year 
  as 
  nigrivittatus. 
  

  

  Cebus 
  castaneus 
  I. 
  Geoffroy 
  (1851, 
  p. 
  46). 
  A 
  representative 
  of 
  

   nigrivittatus 
  nearest, 
  perhaps, 
  to 
  olivaceus. 
  The 
  type, 
  sent 
  from 
  

   Cayenne 
  in 
  1819, 
  was 
  mounted 
  and 
  now 
  is 
  in 
  very 
  poor 
  condition. 
  

   On 
  the 
  assumption 
  that 
  the 
  monkey 
  originated 
  somewhere 
  along 
  the 
  

   coast 
  of 
  French 
  Guiana, 
  it 
  could 
  hardly 
  be 
  synonymized 
  with 
  olivaceus, 
  

   which, 
  according 
  to 
  Schomburgk, 
  does 
  not 
  occur 
  anywhere 
  below 
  

   3,000 
  feet 
  in 
  the 
  Mount 
  Roraima 
  region. 
  It 
  most 
  probably 
  is 
  the 
  

   same 
  as 
  the 
  British 
  Guianan 
  Cebus 
  identified 
  by 
  Elliot 
  and 
  by 
  Tate 
  as 
  

   Cebus 
  apella 
  apella. 
  

  

  Cebus 
  Pucheranii 
  Dahlbom 
  (1856, 
  pp. 
  161, 
  165). 
  A 
  new 
  name 
  for 
  

   the 
  "Ce. 
  capucinus 
  Is. 
  Geoff. 
  St. 
  Hil. 
  non 
  Linnaei. 
  America 
  meridi- 
  

   onal." 
  The 
  name 
  was 
  proposed 
  in 
  honor 
  of 
  Pucheran, 
  who 
  "Simian 
  

   capucinum 
  Lin. 
  a 
  Cebo 
  capucino 
  Is. 
  Geoffr. 
  primus 
  rite 
  distinxit." 
  

   References 
  to 
  Pucheran's 
  views 
  are 
  given 
  in 
  the 
  above 
  discussions 
  of 
  

   capucinus 
  and 
  olivaceus. 
  This 
  last 
  name, 
  and 
  nigrivittatus, 
  have 
  pri- 
  

   ority 
  over 
  pucheranii 
  for 
  capucinus 
  of 
  authors. 
  It 
  will 
  be 
  noted, 
  

   incidentally, 
  that 
  the 
  description 
  of 
  pucheranii 
  is 
  included 
  by 
  Dahlbom 
  

   in 
  his 
  "tufted" 
  group. 
  Hence, 
  the 
  name 
  is 
  in 
  no 
  case 
  valid 
  for 
  that 
  

   part 
  of 
  capucinus 
  I. 
  Geoffroy 
  which 
  is 
  of 
  authors 
  but 
  could 
  apply 
  

   to 
  the 
  three 
  "tufted" 
  menagerie 
  specimens 
  fisted 
  by 
  I. 
  Geoffroy 
  (1851, 
  

   p. 
  46) 
  under 
  the 
  name 
  capucinus. 
  

  

  Cebus 
  paraguayanus 
  Reichenbach 
  (1862, 
  p. 
  41, 
  fig. 
  118). 
  The 
  

   description 
  and 
  figure 
  are 
  based 
  on 
  the 
  brown 
  "untufted" 
  sajou 
  mdle 
  

   of 
  Cuvier, 
  while 
  the 
  name 
  is 
  taken 
  from 
  Fischer's 
  Cebus 
  apella 
  para- 
  

   guayanus, 
  equivalent 
  to 
  Azara's 
  "cay," 
  a 
  "tufted" 
  form. 
  Cabrera 
  

   (1939, 
  p. 
  34) 
  discussed 
  this 
  subject 
  fully 
  showing 
  the 
  untenability 
  of 
  

   the 
  name 
  proposed 
  by 
  Reichenbach. 
  

  

  Cebus 
  leucocephalus 
  Gray 
  (1865, 
  p. 
  827, 
  fig. 
  4). 
  A 
  member 
  of 
  the 
  

   albifrons 
  group 
  and 
  generally 
  considered 
  a 
  synonym 
  of 
  versicolor. 
  

   However, 
  leucocephalus 
  is 
  distinctly 
  darker 
  than 
  versicolor 
  and, 
  ap- 
  

   parently, 
  representative 
  of 
  the 
  dark 
  brown 
  albifrons 
  of 
  northeastern
