  PITHECUS 
  

  

  described 
  as 
  brown, 
  washed 
  over 
  the 
  outer 
  side 
  of 
  the 
  fore-limbs, 
  and 
  

   more 
  especially 
  between 
  the 
  shoulders 
  and 
  back 
  of 
  the 
  neck 
  with 
  

   yellowish, 
  which 
  appears 
  in 
  certain 
  lights 
  as 
  pale 
  golden, 
  passing 
  on 
  the 
  

   upper 
  surface 
  of 
  the 
  head 
  into 
  a 
  pale 
  yellowish 
  brown. 
  The 
  general 
  

   brownish 
  tint 
  is 
  darkest 
  on 
  the 
  flanks, 
  where 
  it 
  has 
  a 
  fuliginous 
  tinge, 
  

   and 
  down 
  the 
  front 
  margin 
  of 
  the 
  fore-limbs, 
  over 
  the 
  outer 
  surface 
  

   of 
  the 
  thighs, 
  the 
  dorsi 
  of 
  the 
  feet 
  and 
  on 
  the 
  tail. 
  The 
  inside 
  of 
  

   the 
  limbs 
  and 
  the 
  under 
  surface 
  generally 
  are 
  much 
  paler 
  than 
  the 
  

   upper 
  parts, 
  and 
  have 
  a 
  yellowish 
  tint, 
  inclining 
  to 
  gray. 
  Behind 
  the 
  

   angle 
  of 
  the 
  mouth, 
  and 
  below 
  and 
  behind 
  the 
  ears 
  and 
  on 
  the 
  chin, 
  

   the 
  hair 
  is 
  rather 
  long 
  and 
  nearly 
  of 
  the 
  same 
  colour 
  as 
  the 
  under 
  sur- 
  

   face, 
  but 
  slightly 
  tipped 
  with 
  blackish. 
  There 
  is 
  a 
  moderately 
  dense 
  

   line 
  of 
  rather 
  long 
  super-orbital 
  hairs 
  with 
  a 
  pencil 
  of 
  similar 
  hairs 
  

   extending 
  backwards 
  from 
  the 
  external 
  orbital 
  angle 
  of 
  the 
  frontals. 
  

   The 
  hair 
  generally 
  is 
  wavy, 
  and 
  on 
  the 
  shoulders 
  and 
  between 
  them 
  

   above 
  and 
  on 
  the 
  sides 
  of 
  the 
  chest 
  it 
  is 
  much 
  longer 
  than 
  on 
  the 
  hind 
  

   part 
  of 
  the 
  body, 
  with 
  the 
  exception 
  of 
  the 
  dark 
  hairs 
  on 
  the 
  lower 
  part 
  

   of 
  the 
  flanks, 
  which 
  are 
  also 
  rather 
  long. 
  The 
  hair 
  on 
  the 
  vertex 
  

   radiates 
  from 
  a 
  point 
  of 
  about 
  one 
  inch 
  above 
  the 
  level 
  of 
  the 
  super- 
  

   orbital 
  ridge, 
  and 
  a 
  few 
  of 
  the 
  front 
  hairs 
  are 
  directed 
  forwards, 
  but 
  

   the 
  mass 
  outwards 
  and 
  slightly 
  backwards, 
  which 
  is 
  also 
  the 
  direction 
  

   of 
  the 
  hairs 
  to 
  the 
  radiating 
  point. 
  There 
  are 
  a 
  few 
  long, 
  black 
  super- 
  

   ciliary 
  hairs, 
  also 
  others 
  on 
  the 
  upper 
  lip 
  and 
  skin. 
  The 
  callosities 
  are 
  

   closely 
  surrounded 
  by 
  the 
  fur. 
  The 
  length 
  of 
  the 
  animal 
  along 
  the 
  

   curve 
  of 
  the 
  head 
  and 
  back 
  is 
  26.75 
  inches, 
  the 
  tail 
  measuring 
  9^4 
  

   inches." 
  

  

  The 
  type 
  of 
  Macacus 
  problematicus 
  Gray, 
  in 
  the 
  British 
  Museum 
  

   is 
  a 
  moderately 
  sized 
  brown 
  monkey 
  without 
  any 
  special 
  character- 
  

   istics 
  to 
  distinguish 
  it 
  from 
  many 
  others. 
  It 
  is 
  of 
  one 
  uniform 
  tint 
  

   over 
  the 
  whole 
  exterior 
  portion 
  of 
  the 
  body 
  and 
  limbs, 
  hands 
  and 
  feet, 
  

   a 
  sepia 
  color 
  becoming 
  yellowish 
  gray 
  on 
  the 
  under 
  parts 
  and 
  inner 
  

   side 
  of 
  limbs, 
  tail 
  brown, 
  paler 
  than 
  body, 
  some 
  stiff 
  black 
  hairs 
  on 
  

   the 
  forehead 
  over 
  the 
  eyes. 
  The 
  type 
  was 
  purchased 
  from 
  the 
  

   Zoological 
  Society, 
  was 
  an 
  immature 
  individual 
  and 
  had 
  lived 
  most 
  

   of 
  its 
  life 
  in 
  captivity. 
  It 
  is 
  practically 
  impossible 
  to 
  refer 
  this 
  type 
  

   with 
  certainty 
  to 
  any 
  recognized 
  species, 
  and 
  there 
  is 
  little 
  to 
  be 
  said 
  in 
  

   defense 
  of 
  a 
  habit 
  of 
  describing 
  individuals 
  from 
  Zoological 
  Gardens, 
  

   that 
  are 
  immature, 
  have 
  passed 
  most 
  of 
  their 
  lives 
  in 
  captivity, 
  and 
  

   in 
  the 
  majority 
  of 
  cases 
  with 
  no 
  ascertained 
  locality. 
  The 
  best 
  thing 
  

   to 
  do 
  with 
  all 
  such 
  specimens 
  is 
  to 
  declare 
  them 
  undeterminable, 
  and 
  

   strike 
  them 
  out 
  of 
  our 
  list. 
  Such 
  specimens 
  as 
  this 
  type 
  of 
  M.
