  should 
  be 
  so 
  greatly 
  confused. 
  The 
  writer 
  has 
  examined 
  all 
  the 
  

   types 
  of 
  Cebus 
  that 
  are 
  accessible 
  at 
  the 
  present 
  time, 
  and 
  his 
  

   descriptions 
  have 
  been 
  taken 
  from 
  them 
  as 
  they 
  now 
  appear, 
  some 
  

   much 
  changed 
  from 
  their 
  former 
  state, 
  with 
  the 
  delicate 
  colors 
  gone, 
  

   and 
  occasionally 
  important 
  portions 
  of 
  the 
  fur 
  having 
  disappeared 
  

   also 
  ; 
  but 
  the 
  manner 
  in 
  which 
  the 
  various 
  colors 
  are 
  distributed 
  could 
  

   in 
  some 
  cases 
  still 
  be 
  traced, 
  and 
  an 
  idea 
  of 
  the 
  animal's 
  original 
  

   appearance 
  might 
  thus 
  be 
  obtained. 
  When 
  types 
  were 
  altogether 
  

   missing, 
  and 
  the 
  description 
  first 
  given 
  was 
  insufficient 
  for 
  the 
  recog- 
  

   nition 
  of 
  the 
  species, 
  and 
  there 
  was 
  no 
  other 
  example 
  from 
  the 
  same 
  

   locality 
  to 
  show 
  what 
  the 
  type 
  may 
  have 
  been, 
  little 
  could 
  be 
  accom- 
  

   plished, 
  and 
  the 
  species 
  would 
  have 
  to 
  be 
  dropped 
  altogether 
  as 
  unde- 
  

   terminable, 
  or 
  allowed 
  to 
  stand 
  with 
  the 
  original 
  description 
  as 
  a 
  

   guide, 
  in 
  hopes 
  that 
  some 
  one 
  more 
  fortunate, 
  might 
  in 
  the 
  future 
  be 
  

   able 
  to 
  discover 
  what 
  it 
  really 
  might 
  be. 
  The 
  species 
  that 
  follow 
  are 
  

   believed 
  to 
  be 
  all 
  of 
  the 
  genus 
  Cebus 
  existing 
  to-day 
  that 
  are 
  known, 
  

   twenty-four 
  in 
  all, 
  but 
  the 
  types 
  of 
  some, 
  embraced 
  in 
  the 
  various 
  

   synonyms, 
  no 
  longer 
  existing, 
  the 
  conclusions 
  in 
  such 
  instances 
  have 
  

   been 
  reached 
  through 
  the, 
  often 
  imperfect 
  or 
  too 
  brief, 
  descriptions 
  

   originally 
  published.

  Two 
  species 
  of 
  Cebus 
  are 
  given 
  in 
  the 
  list 
  of 
  Simiae, 
  5. 
  apella 
  

   and 
  S. 
  capucinus. 
  These 
  were 
  described 
  by 
  Linnaeus 
  in 
  a 
  

   work 
  entitled 
  'Museum 
  Regis 
  Adolphi 
  Frederici,' 
  published 
  in 
  

   1754. 
  The 
  original 
  description, 
  slightly

  The 
  two 
  species 
  of 
  Cebus 
  described 
  in 
  the 
  10th 
  edition 
  appear 
  

   again 
  here, 
  with 
  the 
  same 
  descriptions, 
  but 
  in 
  the 
  case 
  of 
  C 
  

   capucinus 
  farther 
  on, 
  Linnaeus 
  unfortunately, 
  gives 
  a 
  more 
  

   lengthy 
  description 
  and 
  in 
  certain 
  parts 
  a 
  very 
  erroneous 
  one, 
  

   i. 
  e. 
  "pectus 
  f 
  errugineus," 
  which 
  in 
  no 
  wise 
  is 
  ever 
  the 
  case 
  in 
  the 
  

   color 
  of 
  the 
  animal 
  he 
  originally 
  described 
  and 
  figured 
  as 
  C. 
  

   capucinus. 
  This 
  error 
  has 
  been 
  the 
  cause 
  of 
  the 
  transference 
  

   of 
  the 
  name 
  C. 
  capucinus 
  to 
  an 
  entirely 
  different 
  animal, 
  the 
  

   one 
  Linnaeus 
  called 
  C. 
  apella, 
  and 
  these 
  two 
  species 
  have 
  had 
  

   the 
  wrong 
  appellation 
  applied 
  to 
  them 
  since 
  that 
  time 
  by 
  all 
  

   Mammalogists, 
  even 
  though 
  some 
  writers 
  had 
  discovered 
  the
