  Hirst 
  on 
  Scorpions 
  and 
  Sulifugce 
  

  

  a 
  variety 
  of 
  the 
  latter. 
  I 
  think 
  that 
  it 
  is 
  undoubtedly 
  more 
  

   closely 
  allied 
  to 
  B. 
  emini 
  than 
  to 
  B. 
  minax, 
  but 
  that 
  it 
  should 
  

   be 
  regarded 
  as 
  a 
  distinct 
  species 
  and 
  not 
  merely 
  as 
  a 
  variety. 
  

   The 
  male 
  can 
  be 
  readily 
  distinguished 
  from 
  that 
  of 
  B. 
  emini 
  

   by 
  its 
  much 
  narrower 
  hand, 
  which 
  is 
  only 
  slightly 
  broader 
  

   than 
  the 
  brachium, 
  and 
  longer 
  and 
  more 
  slender 
  fingers 
  ; 
  

   moreover, 
  the 
  movable 
  finger 
  has 
  only 
  a 
  very 
  slight 
  low 
  

   lobation, 
  and 
  the 
  immovable 
  finger 
  is 
  without 
  any 
  definite 
  

   lobe. 
  The 
  hand 
  and 
  fingers, 
  indeed, 
  are 
  very 
  similar 
  in 
  

   shape 
  in 
  both 
  sexes 
  in 
  B. 
  polystictus 
  and 
  resemble 
  closely 
  

   those 
  of 
  the 
  female 
  of 
  B. 
  emini. 
  In 
  the 
  male 
  of 
  B. 
  emini, 
  

   however, 
  the 
  hand 
  is 
  very 
  much 
  broader 
  than 
  the 
  brachium, 
  

   and 
  the 
  fingers 
  are 
  very 
  different 
  in 
  shape 
  to 
  those 
  of 
  the 
  

   female; 
  they 
  are 
  shorter 
  and 
  stouter, 
  and 
  both 
  the 
  movable 
  

   one 
  and 
  the 
  immovable 
  one 
  in 
  the 
  adult 
  are 
  furnished 
  

   with 
  very 
  distinct 
  lobes, 
  that 
  of 
  the 
  immovable 
  finger 
  being 
  

   especially 
  strong. 
  In 
  addition 
  to 
  the 
  specimens 
  of 
  B. 
  poly- 
  

   stictus 
  determined 
  by 
  Mr. 
  Pocock, 
  I 
  have 
  examined 
  sixteen 
  

   males 
  and 
  forty-three 
  females 
  and 
  young 
  from 
  Berbera, 
  and 
  

   eleven 
  males 
  and 
  twenty-two 
  females 
  from 
  the

   Mountains 
  behind 
  Berbera;

  specimens

  Remarks. 
  — 
  This 
  scorpion 
  was 
  described 
  from 
  specimens 
  

   obtained 
  at 
  Duroor 
  and 
  Suakin. 
  As 
  pointed 
  out 
  by 
  

   Mr. 
  Pocock, 
  it 
  can 
  be 
  distinguished 
  from 
  Parabuthus 
  liosoma 
  

   [typical 
  form] 
  by 
  the 
  greater 
  slenderness 
  of 
  the 
  tail 
  and 
  by 
  

   the 
  presence 
  of 
  a 
  basal 
  tubercle 
  on 
  the 
  fingers 
  of 
  tlie 
  hand, 
  

   &c. 
  It 
  must 
  be 
  noted, 
  however, 
  that 
  the 
  width 
  of 
  the 
  tail 
  

   varies 
  somewhat 
  even 
  in 
  specimens 
  from 
  the 
  same 
  locality.
