  similar 
  specimen, 
  which 
  died 
  twenty-six 
  days 
  afterwards. 
  It 
  was 
  a 
  

   young 
  half 
  grown 
  male. 
  I 
  have 
  compared 
  its 
  skin 
  with 
  the 
  typical 
  

   specimen 
  of 
  A. 
  griscescens, 
  now 
  in 
  the 
  British 
  Museum, 
  and 
  believe 
  

   them 
  to 
  be 
  probably 
  identical. 
  The 
  young 
  animal 
  is, 
  as 
  might 
  be 
  

   expected, 
  rather 
  lighter 
  in 
  color, 
  particularly 
  below, 
  but 
  above 
  exhibits 
  

   the 
  same 
  mixture 
  of 
  black 
  and 
  grayish 
  hairs 
  as 
  in 
  the 
  original. 
  The 
  tail 
  

   is 
  nearly 
  black 
  above, 
  with 
  a 
  light 
  line 
  of 
  grayish 
  hairs 
  below. 
  The 
  

   length 
  of 
  the 
  body 
  is 
  fourteen 
  inches, 
  of 
  the 
  tail 
  sixteen 
  inches. 
  There 
  

   is 
  no 
  rudiment 
  of 
  a 
  thumb 
  apparent. 
  

  

  "It 
  is 
  possible 
  this 
  may 
  be 
  a 
  good 
  species, 
  and 
  still 
  turn 
  up 
  in 
  

   some 
  part 
  of 
  the 
  Central 
  American 
  or 
  Colombian 
  Coast, 
  whence 
  Mr. 
  

   Greey's 
  specimen 
  probably 
  came, 
  but 
  I 
  do 
  not 
  yet 
  consider 
  it 
  sufficiently 
  

   well 
  established." 
  

  

  This 
  specimen, 
  described 
  by 
  Dr. 
  Sclater, 
  I 
  found 
  in 
  the 
  Collection 
  

   of 
  the 
  Paris 
  Museum. 
  

  

  A 
  skull 
  in 
  the 
  Paris 
  Museum 
  stated 
  to 
  have 
  been 
  obtained 
  from 
  

   the 
  Zoological 
  Society 
  of 
  London 
  bears 
  upon 
  it 
  the 
  name 
  "Ateles 
  ( 
  !) 
  

   cinerascens." 
  This 
  is 
  evidently 
  an 
  error 
  as 
  there 
  is 
  no 
  Spider 
  

   Monkey 
  with 
  that 
  appellation. 
  It 
  was 
  most 
  probable 
  that 
  grisescens 
  

   was 
  the 
  word 
  intended 
  to 
  have 
  been 
  written, 
  and 
  it 
  doubtless 
  belonged 
  

   to 
  Sclater's 
  example. 
  The 
  dimensions 
  of 
  this 
  skull 
  are 
  as 
  follows: 
  

   total 
  length, 
  119; 
  occipito-nasal 
  length, 
  99; 
  Hensel, 
  69; 
  zygomatic 
  

   width, 
  62 
  ; 
  intertemporal 
  width, 
  47.5 
  ; 
  breadth 
  of 
  braincase, 
  59 
  ; 
  median 
  

   length 
  of 
  nasals, 
  17; 
  length 
  of 
  upper 
  molar 
  series, 
  25; 
  length 
  of 
  

   mandible, 
  62 
  ; 
  length 
  of 
  lower 
  molar 
  series, 
  29. 
  

  

  As 
  the 
  type 
  of 
  A. 
  cucullatus 
  was 
  without 
  a 
  skull, 
  no 
  comparison 
  

   between 
  it 
  and 
  the 
  one 
  from 
  which 
  the 
  measurements 
  given 
  above 
  

   were 
  taken, 
  could 
  be 
  made.
