  Color. 
  Entirely 
  black 
  except 
  the 
  under 
  side 
  of 
  the 
  tail 
  which 
  is 
  

   tinted 
  with 
  yellowish 
  brown, 
  the 
  basal 
  portion 
  of 
  the 
  hairs 
  being 
  of 
  

   that 
  color, 
  as 
  is 
  also 
  the 
  basal 
  part 
  of 
  the 
  hairs 
  on 
  arms 
  and 
  legs. 
  

   Intermixed 
  with 
  the

  hairs 
  are 
  long 
  gray, 
  or 
  silvery, 
  or 
  golden 
  

   hairs, 
  not 
  sufficiently 
  numerous 
  to 
  give 
  a 
  tint 
  to 
  the 
  black 
  color, 
  this 
  

   being 
  produced 
  only 
  where 
  the 
  basal 
  part 
  of 
  the 
  hairs 
  are 
  yellow 
  or 
  

   golden, 
  which 
  is 
  most 
  apparent 
  on 
  the 
  limbs,

  part 
  

   of

  The 
  type 
  specimen 
  has 
  the 
  appearance 
  of 
  a 
  black 
  monkey, 
  with 
  a 
  

   moderate 
  number 
  of 
  golden 
  brown 
  and 
  silvery 
  hairs 
  intermingled. 
  In 
  

   some 
  lights 
  these 
  are 
  hardly 
  perceptible, 
  but 
  in 
  strong 
  lights 
  they 
  are 
  

   conspicuous. 
  It 
  is 
  a 
  rather 
  small 
  animal 
  about 
  the 
  size 
  of 
  A. 
  cucul- 
  

   latus. 
  It 
  certainly 
  is 
  a 
  peculiar 
  looking 
  example, 
  but 
  its 
  real 
  claim 
  to 
  

   specific 
  distinctness 
  can 
  only 
  be 
  satisfactorily 
  proved 
  by 
  the 
  acquisition 
  

   of 
  more 
  specimens. 
  It 
  is 
  nearest 
  in 
  its 
  state 
  of 
  coloration 
  to 
  A. 
  

   cucullatus 
  and 
  it 
  is 
  possible 
  they 
  may 
  eventually 
  prove 
  to 
  be 
  the 
  

   same, 
  but 
  placed 
  side 
  by 
  side 
  this 
  example 
  is 
  much 
  blacker. 
  Dr. 
  

   Sclater, 
  writing 
  about 
  this 
  animal 
  in 
  1871 
  (1. 
  c.) 
  says 
  "Dr. 
  Gray 
  

   founded 
  this 
  species 
  of 
  Ateles 
  ( 
  !) 
  upon 
  a 
  specimen 
  that 
  was 
  living 
  

   in 
  our 
  Gardens 
  in 
  1864. 
  It 
  was 
  brought 
  home 
  by 
  Mr. 
  E. 
  Greey, 
  F. 
  Z. 
  S. 
  

   (who 
  was 
  at 
  that 
  time 
  an 
  officer 
  in 
  the 
  West 
  Indian 
  Mail 
  Company's 
  

   Steamship 
  Shannon-, 
  on 
  the 
  29th 
  Oct., 
  1864). 
  Referring 
  to 
  Mr. 
  

   Greey's 
  letters, 
  I 
  regret 
  to 
  find 
  that 
  he 
  did 
  not 
  know 
  the 
  exact 
  locality 
  

   of 
  it, 
  but 
  only 
  states 
  that 
  it 
  was 
  obtained 
  by 
  him 
  at 
  St. 
  Thomas's, 
  and 
  

   had 
  already 
  been 
  three 
  years 
  in 
  captivity, 
  so 
  that 
  it 
  was 
  quite 
  adult. 
  

  

  "In 
  1889 
  (Oct. 
  12) 
  we 
  purchased 
  of 
  a 
  London 
  dealer
