  hypoleuca 
  Humboldt, 
  an 
  albifrons 
  (see 
  below). 
  However, 
  authors 
  

   have 
  heretofore 
  regarded 
  Buffon's 
  (and 
  Smellie's) 
  monkey 
  as 
  a 
  black 
  

   white-fronted 
  Cebus 
  equivalent 
  to 
  Cebus 
  capucinus 
  Linnaeus, 
  1758. 
  

   Thus, 
  Simia 
  capucinus 
  albulus 
  can 
  be 
  confused 
  with 
  any 
  one 
  of 
  three 
  

   distinct 
  species 
  of 
  Cebus. 
  It 
  could 
  be 
  regarded 
  as 
  (1) 
  a 
  variety 
  of 
  

   C. 
  apella, 
  based 
  on 
  Kerr's 
  concept 
  of 
  capucinus, 
  (2) 
  a 
  brown 
  pale- 
  

   fronted 
  Cebus 
  (albifrons) 
  based 
  on 
  the 
  reference 
  to 
  the 
  "Sai 
  with 
  a 
  

   White 
  Tliroat," 
  and 
  (3) 
  a 
  black 
  white-fronted 
  Cebu^ 
  based 
  on 
  the 
  

   misrepresentation 
  of 
  the 
  sai 
  a 
  gorge 
  blanche 
  as 
  such. 
  To 
  avoid 
  this 
  

   confusion, 
  the 
  name 
  albulus 
  is 
  here 
  restricted 
  to 
  Kerr's 
  concept 
  of 
  the 
  

   species 
  capucinus. 
  Hence, 
  albulus 
  is 
  either 
  a 
  synonym 
  of 
  C. 
  apella 
  

   or 
  unidentifiable. 
  

  

  The 
  assumption 
  that 
  both 
  the 
  sai 
  d, 
  gorge 
  blanche 
  and 
  Simia 
  hypo- 
  

   leuca 
  Humboldt 
  are 
  black 
  (capucinus) 
  rather 
  than 
  brown 
  (albifrons) 
  

   monkeys 
  led 
  Allen 
  (1895, 
  p. 
  186) 
  to 
  consider 
  albulus 
  an 
  earlier 
  name 
  

   for 
  hypoleucus. 
  Pusch 
  (1941, 
  p. 
  191) 
  identified 
  one 
  black 
  white- 
  

   fronted 
  Cebus 
  from 
  Cartagena, 
  and 
  others 
  without 
  locality 
  data, 
  as 
  

   C. 
  capucinus 
  albulus. 
  This 
  is 
  untenable 
  as 
  albulus 
  is 
  not 
  only 
  un- 
  

   identifiable 
  as 
  a 
  true 
  capucinus 
  but 
  its 
  habitat 
  was 
  originally 
  stated 
  

   to 
  be 
  Brazil. 
  Furthermore, 
  Cartagena 
  is 
  within 
  the 
  range 
  Pusch 
  had 
  

   already 
  assigned 
  to 
  the 
  typical 
  race 
  of 
  C. 
  capucinus. 
  

  

  Cercopithecus 
  flavus 
  Goldfuss 
  (Vergleichende 
  Naturbeschreibung 
  

   Saugethiere, 
  Abt. 
  1, 
  p. 
  74, 
  1809). 
  The 
  name 
  was 
  exhumed 
  by 
  Pusch 
  

   (1941, 
  p. 
  210) 
  as 
  representing 
  a 
  valid 
  subspecies 
  of 
  the 
  later 
  described 
  

   albifrons 
  Humboldt. 
  Pusch 
  added 
  barbatus 
  Geoffroy, 
  Brissonii 
  

   Lesson, 
  and 
  "flavescens 
  Reichenbach" 
  to 
  the 
  synonymy 
  of 
  flavus, 
  

   which 
  he 
  described 
  as 
  a 
  uniformly 
  pale 
  monkey 
  but 
  with 
  cap 
  and 
  

   back 
  of 
  head 
  brown. 
  Pusch 
  had 
  only 
  a 
  skull 
  of 
  a 
  menagerie 
  specimen 
  

   of 
  imknown 
  origin 
  on 
  which 
  to 
  base 
  identification, 
  diagnosis, 
  distri- 
  

   bution 
  (Guiana), 
  and 
  synonymy. 
  Goldfuss' 
  publication 
  was 
  not 
  

   available, 
  but 
  Dr. 
  Remington 
  Kellogg 
  kindly 
  provided 
  the 
  writer 
  

   with 
  a 
  copy 
  of 
  the 
  original 
  page 
  containing 
  the 
  description 
  of 
  Cer- 
  

   copithecus 
  flavus. 
  Here 
  flavus 
  is 
  shown 
  as 
  an 
  emended 
  form 
  of 
  the 
  

   name 
  for 
  "Der 
  Gelbe 
  Halbaffe. 
  Simia 
  flavia 
  v. 
  Schreb. 
  suppl. 
  

   t.Sl.B." 
  Goldfuss' 
  entire 
  description 
  is 
  derived 
  from 
  the 
  colored 
  

   plate 
  cited 
  (seefiavia 
  Schreber, 
  above). 
  

  

  Simia 
  albifrons 
  Humboldt 
  (1812, 
  pp. 
  324-356). 
  The 
  name 
  here 
  

   adopted 
  as 
  the 
  earliest 
  valid 
  one 
  for 
  the 
  brown 
  pale-fronted 
  "un- 
  

   tufted" 
  Cebus. 
  No 
  specimen 
  absolutely 
  identifiable 
  with 
  albifrons 
  

   has 
  ever 
  been 
  recorded. 
  This 
  may 
  be 
  attributable 
  to 
  the 
  absence 
  of 
  

   topotypes 
  in 
  any 
  museum 
  collection, 
  to 
  some 
  vagaries 
  in 
  the 
  original 
  

   description, 
  and 
  to 
  the 
  nature 
  of 
  the 
  individual, 
  an 
  animal 
  reared 
  as 
  

   a 
  pet, 
  on 
  which 
  are 
  based 
  the 
  main 
  elements 
  of 
  the 
  original 
  descrip- 
  

   tion. 
  Nevertheless, 
  the 
  original 
  description 
  and 
  comparisons 
  empha-
