  In 
  his 
  paper 
  on 
  Cercopithecus, 
  (Lasiopyga), 
  Mr. 
  Pocock 
  sep- 
  

   arates 
  a 
  specimen 
  from 
  the 
  French 
  Congo, 
  as 
  L. 
  n. 
  brazziformis, 
  on 
  

   account 
  of 
  the 
  legs 
  to 
  ankles 
  being 
  a 
  pale 
  grayish 
  green 
  instead 
  of 
  a 
  

   blackish 
  olive. 
  In 
  the 
  series 
  obtained 
  by 
  Mr. 
  Bates 
  on 
  the 
  River 
  Ja, 
  in 
  

   Cameroon, 
  and 
  all 
  of 
  which 
  Mr. 
  Pocock 
  states 
  he 
  could 
  not 
  dis- 
  

   tinguish 
  specifically 
  from 
  his 
  L. 
  neglecta, 
  (L. 
  brazz^e), 
  is 
  an 
  example 
  

   with 
  legs 
  colored 
  precisely 
  like 
  the 
  one 
  from 
  the 
  French 
  Congo. 
  This 
  

   last 
  is 
  not 
  sexed, 
  but 
  the 
  one 
  from 
  Cameroon 
  is 
  marked 
  female. 
  It 
  

   may 
  be 
  possible 
  that 
  the 
  color 
  of 
  the 
  legs 
  may 
  be 
  attributed 
  to 
  sex, 
  but 
  

   the 
  fact 
  that 
  both 
  styles 
  of 
  coloring 
  were 
  found 
  in 
  individuals 
  taken 
  in 
  

   the 
  same 
  place 
  in 
  Cameroon, 
  would 
  indicate 
  that 
  the 
  difference 
  in 
  hue 
  

   in 
  the 
  legs 
  was 
  not 
  a 
  specific 
  character, 
  but 
  must 
  be 
  attributed 
  to 
  some 
  

   other 
  cause, 
  such 
  as 
  age 
  or 
  sex, 
  or 
  possibly 
  to 
  individual 
  variation. 
  I 
  

   have 
  therefore 
  placed 
  brazzceformis 
  among 
  the 
  synonyms 
  of 
  L. 
  brazz.e. 
  

  

  Mr. 
  Pocock 
  described 
  in 
  the 
  Proc. 
  Zool. 
  Soc. 
  Lond., 
  1908, 
  p. 
  158, 
  

   pi. 
  X, 
  fig. 
  2, 
  a 
  young 
  animal 
  without 
  locality 
  or 
  history 
  as 
  C. 
  ezrcc, 
  and 
  

   which 
  differs 
  from 
  L. 
  brazz^e 
  in 
  not 
  having 
  the 
  black 
  on 
  the 
  hinder 
  

   part 
  of 
  the 
  head, 
  and 
  the 
  outer 
  side 
  of 
  the 
  limbs, 
  hands, 
  and 
  feet 
  not 
  

   yet 
  jet 
  black. 
  The 
  specimen 
  is 
  so 
  young, 
  and 
  its 
  pelage 
  so 
  affected 
  by 
  

   captivity 
  (the 
  hair 
  on 
  the 
  loins 
  having 
  all 
  been 
  worn 
  away 
  by 
  the 
  rope 
  

   or 
  chain 
  that 
  held 
  it, 
  and 
  the 
  tail 
  having 
  lost 
  all 
  its 
  hair, 
  except 
  a 
  little 
  

   at 
  the 
  root), 
  that 
  it 
  makes 
  a 
  most 
  unsatisfactory 
  type 
  for 
  a 
  distinct 
  

   form, 
  and 
  it 
  is 
  to 
  be 
  regretted 
  that 
  such 
  specimens 
  should 
  ever 
  be 
  

   selected 
  to 
  be 
  the 
  unique 
  representative 
  of 
  a 
  new 
  species. 
  At 
  present 
  

   it 
  can 
  only 
  be 
  surmised 
  what 
  the 
  full 
  grown 
  animal 
  would 
  look 
  like, 
  but 
  

   probably 
  it 
  might 
  be 
  recognizable 
  from 
  L. 
  brazzcc 
  by 
  having 
  the 
  head
