  Blaine 
  on 
  the 
  Korrlgum. 
  

  

  This 
  table 
  shows 
  that 
  the 
  several 
  races 
  of 
  korrigum 
  

   separate 
  themselves 
  into 
  two 
  groups, 
  viz. 
  the 
  Western 
  races, 
  

   inhabiting 
  more 
  or 
  less 
  arid 
  desert-regions 
  {horrigum, 
  purpu- 
  

   resccns^ 
  and 
  titmg), 
  and 
  the 
  Eastern 
  races, 
  inhabiting 
  mostly 
  

   f(n-tile 
  well-watered 
  regions 
  {topi, 
  iiganda^, 
  and 
  eurus). 
  Tiie 
  

   skulls 
  of" 
  the 
  Western 
  races 
  can 
  be 
  distinguished 
  by 
  their 
  

   concave 
  profiles, 
  narrower 
  muzzles, 
  and 
  longer, 
  more 
  re- 
  

   curved, 
  and 
  laterally 
  compressed 
  bonis 
  ; 
  those 
  of 
  the 
  

   Eastern 
  races 
  by 
  their 
  wider 
  skulls, 
  with 
  straighter 
  profiles, 
  

   longer 
  and 
  wider 
  muzzles 
  with 
  longer 
  nasal 
  bones, 
  and 
  by 
  

   their 
  shorter, 
  more 
  upright, 
  and 
  cylindrical 
  horns. 
  

  

  The 
  characteiistic 
  purple 
  bloom, 
  which 
  is 
  absent 
  in 
  korri- 
  

   gum, 
  becomes 
  first 
  a|)parent 
  in 
  the 
  N. 
  Nigerian 
  race 
  purpu- 
  

   rescens, 
  and 
  intensifies 
  until 
  it 
  readies 
  its 
  highest 
  development 
  

   in 
  the 
  East 
  coast 
  topi, 
  wliile 
  the 
  black 
  eye-band 
  follows 
  an 
  

   almost 
  similar 
  course, 
  being 
  fully 
  developed 
  in 
  the 
  South- 
  

   eastern 
  race 
  eurus. 
  

  

  1 
  have 
  included 
  the 
  measurements 
  of 
  a 
  Sassaby 
  skull 
  in 
  

   this 
  table, 
  as 
  it 
  is 
  interesting 
  for 
  comparison. 
  There 
  can 
  be 
  

   no 
  doubt 
  that 
  this 
  antelope 
  is 
  closely 
  related 
  to 
  the 
  Korrigum, 
  

   Q^lie 
  skull 
  is 
  very 
  nearly 
  identical, 
  though 
  rather 
  wider 
  in 
  

   proportion 
  across 
  the 
  orbits 
  and 
  contracted 
  across 
  the 
  forehead. 
  

   The 
  tympanic 
  bullae 
  are 
  rounder 
  and 
  not 
  so 
  prominent 
  and 
  

   conically 
  ridged 
  as 
  in 
  korrigum, 
  and 
  the 
  basi-cranial 
  region 
  

   is 
  shorter. 
  

  

  Ill 
  bodily 
  size 
  this 
  antelope 
  is 
  identical 
  with 
  korrigum, 
  as 
  

   also 
  in 
  colour 
  and 
  distribution 
  of 
  the 
  markings, 
  differing 
  

   only 
  where 
  the 
  greyish 
  patches 
  on 
  the 
  quarters 
  spread 
  along 
  

   the 
  flanks 
  towards 
  the 
  shoulders, 
  and 
  being 
  lighter 
  on 
  the 
  

   inside 
  of 
  the 
  thighs, 
  while 
  the 
  legs 
  from 
  knees 
  and 
  hocks 
  

   downwards 
  to 
  hoofs 
  are 
  a 
  dark 
  tan. 
  

  

  In 
  addition 
  to 
  these 
  races 
  of 
  the 
  Korrigum 
  Mr. 
  Lydekker 
  

   has 
  described 
  selousi^ 
  from 
  the 
  Guas'ngisliu 
  PLiteau 
  in 
  

   British 
  East 
  Africa, 
  a 
  large 
  form 
  distinguished 
  by 
  having 
  a 
  

   tan-coloured 
  aiea 
  round 
  the 
  eyes 
  and 
  muzzle, 
  and 
  jonesi^, 
  a 
  

   ligiit-coloured 
  desert-race 
  from 
  N.W. 
  Kordofan. 
  Herr 
  Ernst 
  

   Schwarz 
  has 
  described 
  koha 
  lyra 
  \ 
  from 
  a 
  skull 
  from 
  the 
  

   Upj)er 
  Sliari 
  region, 
  south 
  of 
  Lake 
  Chad, 
  which 
  resembles 
  

   tiang 
  in 
  being 
  narrow, 
  but 
  has 
  thinner 
  liorns, 
  with 
  their 
  ends 
  

   niaikedly 
  curved 
  upwards 
  and 
  inwards;
