  Sir 
  Harry 
  Johnston 
  writing 
  to 
  Dr. 
  Sclater 
  about 
  the 
  specimen 
  of 
  

   this 
  Monkey 
  from 
  Lake 
  Tanganyika 
  (1. 
  c.) 
  states 
  that, 
  "this 
  is 
  the 
  

   history 
  of 
  the 
  Black 
  Monkey. 
  He 
  was 
  brought 
  from 
  the 
  country 
  of 
  

   Barundi, 
  at 
  the 
  north 
  end 
  of 
  Tanganyika, 
  by 
  Rumaliza, 
  the 
  Arab 
  who 
  

   has 
  been 
  fighting 
  recently 
  with 
  the 
  Belgians. 
  Rumaliza 
  gave 
  it 
  at 
  

   Ujiji 
  to 
  Mr. 
  Swann, 
  then 
  in 
  the 
  service 
  of 
  the 
  London 
  Missionary 
  

   Society. 
  Mr. 
  Swann 
  brought 
  him 
  down 
  to 
  the 
  south 
  end 
  of 
  Tangan- 
  

   yika 
  and 
  gave 
  him 
  to 
  the 
  Mission 
  Station. 
  The 
  Missionary 
  in 
  charge 
  

   of 
  the 
  station 
  subsequently 
  hearing 
  that 
  I 
  was 
  collecting 
  all 
  sorts 
  of 
  

   beasts 
  sent 
  him 
  to 
  me. 
  I 
  got 
  him 
  fetched 
  down 
  from 
  Tanganyika 
  to 
  

   Zomba, 
  and 
  thence 
  as 
  you 
  know 
  to 
  England. 
  He 
  is 
  undoubtedly 
  a 
  

   native 
  of 
  the 
  country 
  at 
  the 
  north 
  end 
  of 
  Lake 
  Tanganyika; 
  in 
  other 
  

   words, 
  of 
  the 
  north 
  eastern 
  border 
  of 
  the 
  great 
  forest 
  region 
  of 
  West 
  

   Africa. 
  Even 
  there 
  he 
  would 
  seem 
  to 
  have 
  been 
  rare, 
  since 
  he 
  was 
  

   given 
  by 
  the 
  natives 
  to 
  Rumaliza 
  as 
  a 
  curiosity." 
  

  

  A 
  whitish 
  monkey 
  from 
  Molinga, 
  Lake 
  Mweru, 
  in 
  the 
  London 
  

   Zoological 
  Gardens 
  was 
  named 
  by 
  Mr. 
  Pocock 
  (1. 
  c.) 
  jamrachi. 
  This 
  

   is 
  undoubtedly 
  an 
  albino, 
  and 
  its 
  locality 
  indicates 
  that 
  it 
  would 
  belong 
  

   to 
  the 
  eastern 
  race 
  of 
  C. 
  albigena, 
  and 
  the 
  name 
  therefore 
  becomes 
  

   a 
  synonym 
  of 
  C. 
  a. 
  johnstoni. 
  Specimens 
  of 
  C. 
  albigena 
  and 
  the 
  

   present 
  race 
  are 
  rather 
  scarce 
  in 
  collections, 
  and 
  it 
  is 
  unusual 
  among 
  

   the 
  Primates 
  to 
  find 
  any 
  species 
  so 
  prone 
  to 
  albinism 
  as 
  this 
  one
