  Remarks. 
  — 
  This 
  example 
  from 
  the 
  Blue 
  Nile 
  is 
  a 
  slight 
  

   variety 
  of 
  P. 
  exitialis. 
  The 
  granulation 
  of 
  the 
  under 
  surface 
  

   of 
  the 
  humerus 
  of 
  the 
  palp 
  is 
  very 
  weak, 
  except 
  at 
  the 
  edges. 
  

   Four 
  complete 
  keels 
  and 
  a 
  short 
  inner 
  keel 
  are 
  present 
  on 
  

   the 
  dorsal 
  surface 
  of 
  the 
  hand, 
  and 
  the 
  tubercles 
  are 
  confluent 
  

   in 
  places, 
  but 
  not 
  nearly 
  to 
  the 
  same 
  extent 
  as 
  in 
  the 
  variety, 
  

   which 
  I 
  describe 
  below 
  under 
  the 
  name 
  sudanicus. 
  

  

  In 
  his 
  account 
  of 
  P. 
  exitialis, 
  Mr. 
  Pocock 
  says 
  that 
  there 
  

   is 
  a 
  single 
  dry 
  specimen 
  from 
  ISchoa 
  in 
  the 
  British 
  Museum 
  

   collection. 
  There 
  are 
  present, 
  however, 
  in 
  the 
  collection, 
  

   three 
  dry 
  examples 
  (co-types) 
  of 
  this 
  species, 
  all 
  of 
  which 
  

   were 
  collected 
  by 
  Sir 
  W. 
  C. 
  Harris 
  at 
  Schoa. 
  Four 
  com- 
  

   plete 
  keels 
  are 
  distinctly 
  visible 
  on 
  the 
  hand 
  of 
  one 
  of 
  these 
  

   specimens, 
  and 
  traces 
  of 
  these 
  keels 
  can 
  be 
  seen 
  in 
  the 
  other 
  

   two 
  and 
  in 
  the 
  variety 
  from 
  Gebel 
  Mel.

  This 
  variety 
  may 
  be 
  compared 
  with 
  the 
  typical 
  form 
  of 
  

   the 
  species 
  (from 
  Schoa) 
  as 
  follows 
  : 
  — 
  Dorsal 
  surface 
  of 
  

   the 
  hand 
  much 
  smoother, 
  nearly 
  the 
  entire 
  surface 
  of 
  the 
  

   lobe 
  being 
  furnished 
  with 
  low 
  anastomosing 
  ridges 
  instead 
  

   of 
  isolated 
  tubercles 
  (these 
  ridges 
  are 
  smaller 
  and 
  narrower 
  

   than 
  those 
  of 
  P 
  . 
  yregvryi, 
  and 
  they 
  are 
  finely, 
  but 
  distinctly, 
  

   punctured 
  as 
  in 
  that 
  species) 
  ; 
  the 
  keels 
  on 
  the 
  under 
  surface 
  

   of 
  the 
  hand 
  are 
  more 
  sparsely 
  and 
  weakly 
  granular 
  than 
  

   in 
  the 
  typical 
  form. 
  Proximal 
  half 
  of 
  the 
  under 
  side 
  

   of 
  the 
  humerus 
  granular 
  as 
  in 
  the 
  typical 
  form. 
  Tarsal 
  

   lobes 
  of 
  posterior 
  legs 
  with 
  three 
  spines, 
  which 
  are 
  arranged 
  

   in 
  the 
  same 
  way 
  as 
  in 
  the 
  typical 
  P. 
  exitialis; 
  the 
  total 
  

   number 
  of 
  spines 
  on 
  the 
  anterior 
  side 
  of 
  the 
  tarsus 
  is 
  four, 
  

   and 
  the 
  total 
  number 
  on 
  the 
  posterior 
  side 
  six 
  or 
  seven. 
  

   Pectinal 
  teeth 
  twenty-one 
  or 
  twenty-two 
  in 
  number. 
  Last 
  

   abdominal 
  sternite 
  without 
  any 
  trace 
  of 
  keels.
