﻿CEBUS

  cauda 
  nigra" 
  ; 
  also, 
  "sub 
  mento 
  vellus 
  breve, 
  densum, 
  atrum, 
  pingue," 
  

   one 
  of 
  the 
  characters 
  of 
  capucinus 
  Auct. 
  The 
  general 
  description 
  

   given 
  in 
  the 
  Mus. 
  Reg. 
  Ad. 
  Fred., 
  exactly 
  covers 
  capucinus 
  Auct., 
  and 
  

   the 
  plate 
  gives 
  most 
  of 
  the 
  characteristic 
  markings, 
  such 
  as 
  the 
  black 
  

   cap 
  on 
  the 
  head 
  extending 
  down 
  the 
  sides 
  of 
  the 
  face 
  and 
  under 
  the 
  

   chin, 
  and 
  the 
  black 
  hands, 
  feet 
  and 
  tail. 
  In 
  both 
  editions 
  of 
  the 
  

   Systema 
  Naturae, 
  1758 
  and 
  1766, 
  the 
  Mus. 
  Reg. 
  Ad. 
  Fred, 
  is 
  the 
  only 
  

   work 
  cited, 
  and 
  the 
  descriptions 
  are 
  too 
  brief 
  to 
  determine 
  the 
  species, 
  

   while 
  that 
  in 
  the 
  work, 
  where 
  the 
  form 
  was 
  first 
  named, 
  is 
  fairly 
  

   comprehensive. 
  

  

  Cebus 
  annellatus 
  Gray, 
  the 
  type 
  of 
  which 
  is 
  before 
  me, 
  appears 
  

   to 
  be 
  nothing 
  but 
  what 
  I 
  call 
  apella 
  Linnaeus, 
  capucinus 
  of 
  Authors, 
  

   in 
  one 
  of 
  its 
  many 
  varietal 
  colorations. 
  The 
  yellowish 
  white 
  of 
  the 
  

   temple 
  extends 
  to 
  the 
  top 
  of 
  the 
  head 
  leaving 
  but 
  a 
  narrow 
  black 
  line 
  

   down 
  the 
  center. 
  The 
  body 
  is 
  pale 
  reddish, 
  the 
  limbs 
  and 
  under 
  parts, 
  

   tail, 
  hands 
  and 
  feet 
  like 
  ordinary 
  apella. 
  Mindful 
  of 
  the 
  immense 
  di- 
  

   versity 
  of 
  color 
  exhibited 
  by 
  this 
  species, 
  which 
  is 
  dependent 
  neither 
  

   upon 
  locality, 
  age 
  nor 
  sex, 
  but 
  is 
  simply 
  individual, 
  I 
  have 
  no 
  hesitation 
  

   in 
  referring 
  Gray's 
  type 
  to 
  the 
  present 
  species 
  and 
  include 
  its 
  name 
  

   among 
  the 
  synonyms. 
  

  

  Cebus 
  olivaceus 
  Schomburgk 
  (1. 
  c). 
  The 
  description 
  given 
  of 
  this 
  

   form, 
  seems 
  nearest 
  to 
  C. 
  apella, 
  but 
  there 
  are 
  discrepancies 
  such 
  as 
  

   "Ausnature 
  der 
  Schultern 
  und 
  Oberarme, 
  die 
  strogelb 
  aussehn," 
  which 
  

   leans 
  more 
  towards 
  C. 
  fatuellus 
  (Linn.), 
  for 
  I 
  do 
  not 
  recall 
  any 
  

   specimen 
  of 
  C. 
  apella 
  at 
  any 
  age 
  with 
  the 
  upper 
  part 
  of 
  arms 
  straw- 
  

   yellow. 
  This 
  part 
  is 
  often 
  very 
  light 
  colored 
  and 
  sometimes 
  in 
  immature 
  

   animals 
  approaches 
  a 
  yellowish 
  tinge, 
  but 
  never 
  so 
  far 
  as 
  I 
  have 
  seen 
  

   a 
  straw-yellow. 
  But 
  as 
  the 
  greater 
  part 
  of 
  Schomburgk's 
  description 
  is 
  

   nearer 
  C. 
  apella 
  (Linn.), 
  than 
  it 
  is 
  to 
  any 
  other 
  species, 
  and 
  C. 
  

   fatuellus 
  (Linn.), 
  is 
  a 
  native 
  of 
  the 
  western 
  part 
  of 
  the 
  continent, 
  

   I 
  have 
  placed 
  it 
  among 
  the 
  synonyms 
  of 
  the 
  former 
  species 
  but 
  with 
  an 
  

   interrogation 
  mark, 
  for 
  I 
  know 
  no 
  other 
  species 
  from 
  the 
  Guianas 
  to 
  

   which 
  it 
  can 
  be 
  referred. 
  

  

  The 
  type 
  of 
  Cebus 
  hypomelas 
  Pucheran, 
  is 
  in 
  the 
  Paris 
  Museum, 
  

   and 
  while 
  the 
  upper 
  parts 
  are 
  Prout's 
  brown, 
  the 
  flanks 
  are 
  redder 
  

   or 
  more 
  russet 
  than 
  is 
  usually 
  seen 
  in 
  typical 
  C. 
  apella, 
  yet 
  mindful 
  of 
  

   how 
  the 
  species 
  varies 
  in 
  coloration, 
  it 
  seems 
  best 
  to 
  refer 
  Pucheran's 
  

   type 
  to 
  the 
  older 
  known 
  form. 
  The 
  type 
  has 
  no 
  history 
  beyond 
  what 
  

   is 
  written 
  on 
  the 
  bottom 
  of 
  the 
  stand 
  "Achete 
  a 
  M. 
  Perdrinelli 
  le 
  8 
  

   fevrier 
  1854, 
  mort 
  a 
  la 
  Menagerie 
  le 
  11 
  fevrier, 
  1854." 
  It 
  therefore 
  

   lived 
  only 
  three 
  days 
  after 
  its 
  purchase. 
  Its 
  patrie 
  is 
  quite 
  unknown.
