  Spix's 
  type 
  is, 
  as 
  the 
  measurement 
  shows, 
  a 
  rather 
  large 
  monkey 
  for 
  

   a 
  member 
  of 
  the 
  genus 
  Cebus. 
  In 
  general 
  appearance 
  it 
  is 
  a 
  pale 
  yel- 
  

   lowish 
  animal 
  tinged 
  in 
  places 
  with 
  reddish, 
  or 
  reddish 
  brown, 
  and 
  

   with 
  a 
  reddish 
  tail. 
  It 
  is 
  in 
  only 
  a 
  fair 
  degree 
  of 
  preservation, 
  and 
  has 
  

   lost 
  considerable 
  hair 
  on 
  various 
  parts 
  of 
  the 
  body. 
  The 
  open 
  mouth 
  

   of 
  the 
  specimen 
  shows 
  the 
  teeth 
  which 
  are 
  remarkable 
  for 
  the 
  great 
  

   length 
  of 
  the 
  canines. 
  Spix's 
  figure 
  is 
  a 
  fair 
  representation 
  of 
  the 
  

   species 
  but 
  is 
  too 
  red, 
  at 
  least 
  as 
  the 
  specimen 
  is 
  to-day. 
  It 
  may 
  pos- 
  

   sibly 
  have 
  faded. 
  According 
  to 
  Spix 
  the 
  specimen 
  came 
  from 
  the 
  

   forest 
  bordering 
  the 
  River 
  Tefre 
  near 
  the 
  village 
  of 
  Ega. 
  

  

  The 
  type 
  is, 
  apparently, 
  the 
  only 
  specimen 
  he 
  procured. 
  It 
  does 
  

   not 
  resemble 
  very 
  closely 
  any 
  of 
  the 
  species 
  of 
  Cebus, 
  but 
  perhaps 
  is 
  

   nearer 
  to 
  C. 
  variegatus 
  than 
  any 
  other 
  though 
  much 
  lighter 
  in 
  color. 
  

  

  Gray's 
  type 
  of 
  C. 
  Havescens 
  is 
  quite 
  immature, 
  probably 
  not 
  more 
  

   than 
  three 
  fourths 
  grown, 
  and 
  it 
  would 
  be 
  a 
  very 
  unsatisfactory 
  repre- 
  

   sentative 
  of 
  a 
  species 
  if 
  distinct 
  from 
  all 
  others, 
  which 
  happily 
  it 
  is 
  DOt 
  

   It 
  is 
  doubtless 
  a 
  young 
  individual 
  of 
  C. 
  unicolor 
  Spix, 
  and 
  therefore 
  

   Gray's 
  name 
  must 
  become 
  a 
  synonym.
