  account 
  of 
  having 
  thus 
  altered 
  his 
  original 
  description, 
  a 
  custom 
  not 
  

   unusual 
  with 
  Linnaeus, 
  and 
  the 
  fact 
  that 
  the 
  12th 
  edition 
  of 
  the 
  Sys- 
  

   tema 
  Naturae 
  is 
  the 
  only 
  one 
  consulted 
  and 
  cited 
  by 
  many 
  naturalists, 
  

   that 
  confusion 
  has 
  arisen 
  with 
  the 
  name 
  of 
  this 
  species 
  and 
  the 
  wrong 
  

   one 
  attributed 
  to 
  it, 
  a 
  name 
  Linnaeus 
  only 
  applied 
  to 
  the 
  animal 
  

   generally 
  known 
  to-day 
  as 
  Cebus 
  hypoleucus, 
  but 
  which 
  in 
  the 
  future 
  

   must 
  be 
  called 
  Cebus 
  capucinus. 
  The 
  original 
  description 
  like 
  all 
  

   given 
  by 
  Linnaeus 
  is 
  brief, 
  but 
  emphasizes 
  the 
  characters 
  of 
  the 
  Monkey 
  

   afterwards 
  called 
  hypoleucus, 
  and 
  if 
  this 
  is 
  not 
  considered 
  sufficient 
  

   evidence, 
  the 
  plates 
  exhibit 
  unmistakably, 
  that 
  Humboldt's 
  species 
  

   was 
  the 
  one 
  Linnaeus 
  originally 
  called 
  capucinus. 
  The 
  subject 
  is 
  fully 
  

   discussed 
  in 
  a 
  paper 
  by 
  the 
  writer 
  published 
  in 
  the 
  Bulletin 
  of 
  the 
  

   American 
  Museum 
  of 
  Natural 
  History 
  for 
  1909. 
  

  

  Schlegel 
  has 
  added 
  to 
  the 
  confusion 
  connected 
  with 
  these 
  animals 
  

   by 
  separating 
  the 
  species 
  from 
  the 
  Guianas, 
  C. 
  apella 
  into 
  two, 
  to 
  

   one 
  of 
  which 
  he 
  gives 
  the 
  name, 
  capucinus, 
  although 
  he 
  was 
  fully 
  

   aware 
  that 
  it 
  was 
  a 
  black 
  and 
  white 
  monkey 
  which 
  was 
  so 
  designated 
  

   by 
  Linnaeus. 
  

  

  C. 
  capucinus 
  Tschudi, 
  Faun. 
  Peruan., 
  p. 
  42, 
  is 
  difficult 
  to 
  charac- 
  

   terize 
  from 
  his 
  short 
  and 
  unsatisfactory 
  description. 
  It 
  is 
  not 
  C. 
  

   capucinus 
  (Linn.), 
  for 
  that 
  species 
  is 
  never 
  "dunkelbraun" 
  or 
  "rotlich 
  

   braun" 
  on 
  any 
  part 
  of 
  its 
  body 
  at 
  any 
  age, 
  and 
  "die 
  Kehle, 
  die 
  Brust, 
  

   der 
  Bauch 
  und 
  die 
  innere 
  Seite 
  der 
  Extremitaten 
  sind 
  weisslich 
  gelb" 
  

   does 
  not 
  describe 
  C. 
  apella 
  (Linn.), 
  very 
  well, 
  nor 
  will 
  it 
  answer 
  for 
  

   any 
  stage 
  of 
  C. 
  fatuellus 
  (Linn.). 
  Besides, 
  the 
  latter 
  species 
  is 
  not 
  

   actually 
  known 
  to 
  be 
  found 
  in 
  Peru, 
  nor 
  is 
  the 
  description 
  suitable 
  for 
  

   C. 
  flavus 
  E. 
  Geoff., 
  from 
  Bolivia. 
  It 
  would 
  seem 
  therefore 
  that 
  C. 
  

   capucinus 
  Tschudi 
  (nee 
  Linn.), 
  must 
  be 
  relegated 
  to 
  the 
  list 
  of 
  unde- 
  

   terminable 
  species 
  of 
  the 
  genus 
  Cebus. 
  

  

  From 
  an 
  examination 
  of 
  the 
  series 
  of 
  C. 
  imitator 
  Thos., 
  from 
  

   Boquete, 
  in 
  the 
  British 
  Museum, 
  it 
  would 
  hardly 
  seem 
  that 
  the 
  speci- 
  

   mens 
  possessed 
  sufficient 
  characters 
  to 
  warrant 
  their 
  separation 
  from 
  

   the 
  typical 
  form. 
  Four 
  females, 
  all 
  there 
  are 
  of 
  this 
  sex, 
  have 
  the 
  hair 
  

   on 
  the 
  forepart 
  of 
  the 
  head 
  much 
  longer 
  than 
  the 
  rest 
  forming 
  a 
  sort 
  

   of 
  bushy 
  tuft, 
  and 
  this 
  is 
  not 
  confined 
  to 
  any 
  particular 
  season 
  of 
  the 
  

   year. 
  The 
  examples 
  were 
  procured 
  at 
  a 
  rather 
  high 
  elevation, 
  4,000 
  

   to 
  4,500 
  feet, 
  and 
  long 
  hair 
  and 
  thick 
  fur 
  would 
  naturally 
  constitute 
  

   the 
  coats 
  of 
  animals 
  living 
  at 
  that 
  height 
  ; 
  but 
  if 
  a 
  low 
  temperature 
  was 
  

   the 
  cause 
  of 
  the 
  existence 
  of 
  these 
  tufts 
  the 
  males 
  should 
  also 
  possess 
  

   them, 
  but 
  they 
  do 
  not 
  and 
  are 
  quite 
  indistinguishable 
  from 
  other 
  mem- 
  

   bers 
  of 
  C. 
  capucinus 
  throughout 
  its 
  range.
