  -closer 
  connection 
  between 
  the 
  prevalence 
  of 
  game 
  and 
  G. 
  morsitans 
  than 
  with 
  any 
  other 
  

   species. 
  This 
  is 
  a 
  subject, 
  however, 
  which 
  demands 
  more 
  concentrated 
  investigation 
  

   in 
  a 
  limited 
  area, 
  and 
  in 
  no 
  part 
  of 
  West 
  Africa 
  could 
  this 
  be 
  more 
  effectively 
  carried 
  

   out 
  than 
  in 
  the 
  Northern 
  Territories 
  of 
  the 
  Gold 
  Coast, 
  where 
  game 
  is, 
  so 
  far 
  as 
  is 
  

   known, 
  restricted 
  in 
  its 
  distribution 
  ; 
  where 
  densely 
  populated 
  and 
  uninhabited 
  areas 
  

   occur 
  ; 
  where 
  cattle 
  seem 
  to 
  thrive 
  in 
  some 
  parts 
  and 
  not 
  in 
  others 
  ; 
  and 
  where 
  

   G. 
  palpalis 
  and 
  G. 
  tachinoides 
  exist 
  side 
  by 
  side, 
  the 
  former 
  predominating 
  south- 
  

   wards 
  and 
  the 
  latter 
  northwards, 
  the 
  same 
  holding 
  good 
  for 
  G. 
  longipalpis 
  and 
  

   >G. 
  morsitans 
  respectively. 
  

  

  VII. 
  Parasites 
  of 
  Game 
  and 
  other 
  Mammals. 
  

   During 
  my 
  tour 
  in 
  the 
  Gold 
  Coast 
  I 
  made 
  a 
  systematic 
  attempt 
  to 
  collect 
  informa- 
  

   tion 
  as 
  to 
  the 
  various 
  parasites 
  harboured 
  both 
  by 
  domestic 
  animals 
  and 
  game, 
  but 
  

   I 
  shall 
  confine 
  myself 
  here 
  only 
  to 
  those 
  which 
  are 
  directly 
  connected 
  with 
  this 
  work. 
  

  

  Blood-Parasites. 
  

  

  Game. 
  — 
  Blood 
  smears 
  taken 
  from 
  eleven 
  different 
  kinds 
  of 
  game 
  gave 
  negative 
  

   Tesults. 
  

  

  Horses. 
  — 
  According 
  to 
  Mr. 
  Beal, 
  the 
  Veterinary 
  Surgeon, 
  Trypanosoma 
  dimorphon, 
  

   T. 
  pecaudi 
  and 
  T. 
  cazalboui 
  are 
  equally 
  prevalent 
  in 
  horses. 
  

  

  Cattle. 
  — 
  Trypanosoma 
  pecaudi 
  and 
  T. 
  cazalboui 
  have 
  been 
  found 
  in 
  cattle. 
  

  

  Sheep. 
  — 
  The 
  trypanosomes 
  found 
  in 
  sheep 
  are 
  the 
  same 
  as 
  those 
  in 
  cattle. 
  

  

  Dogs. 
  — 
  Only 
  Trypanosoma 
  dimorphon 
  has 
  so 
  far 
  been 
  found 
  in 
  dogs. 
  

  

  internal 
  Parasites. 
  

  

  Apart 
  from 
  " 
  worms," 
  only 
  " 
  bots 
  " 
  are 
  found 
  internally. 
  Bots 
  taken 
  from 
  the 
  

   stomach 
  of 
  horses, 
  which 
  had 
  been 
  post-mortemed 
  by 
  Mr. 
  Beal, 
  were 
  identified 
  at 
  

   Yaba 
  as 
  Gastrophilus 
  equi 
  and 
  others 
  found 
  since 
  that 
  time 
  he 
  is 
  inclined 
  to 
  believe 
  

   are 
  Oestrus 
  pecorum. 
  From 
  the 
  nasal 
  sinuses 
  of 
  a 
  haartebeeste 
  shot 
  by 
  the 
  author 
  

   at 
  Tumu 
  several 
  bots 
  were 
  taken 
  ; 
  these 
  have 
  not 
  yet 
  been 
  identified. 
  

  

  External 
  parasites. 
  

  

  The 
  following 
  arthropod 
  parasites 
  were 
  taken 
  from 
  game 
  shot 
  by 
  the 
  author 
  : 
  — 
  

   Amblyomma 
  splendidum 
  from 
  buffalo 
  ; 
  Hyalomma 
  aegyptium 
  and 
  Boophilus 
  decolor- 
  

   atus 
  from 
  roan 
  antelope 
  ; 
  Amblyomma 
  variegatum 
  from 
  haartebeeste 
  ; 
  Rhipicephalus 
  

   simus 
  and 
  Hyalomma 
  aegyptium 
  from 
  wart-hog; 
  Haemaphysalis 
  aciculifer 
  and 
  

   Rhipicephalus 
  simus 
  from 
  reed-buck; 
  Rhipicephalus 
  simus 
  from 
  oribi; 
  and 
  

   E 
  chesty 
  pus 
  sp. 
  from 
  oribi 
  and 
  two 
  species 
  of 
  duiker. 
  

  

  In 
  conclusion, 
  I 
  wish 
  to 
  take 
  this 
  opportunity 
  of 
  thanking 
  His 
  Excellency 
  Sir

  Gold 
  Coast,

  this 
  investigation
