  A 
  number 
  of 
  specimens 
  of 
  this 
  species 
  from 
  Bushire 
  were 
  

   collected 
  and 
  presented 
  to 
  the 
  British 
  Museum 
  by 
  Mr. 
  E. 
  

   Lort 
  Phillips. 
  

  

  Although 
  this 
  species 
  bears 
  a 
  general 
  resemblance 
  to 
  

   several 
  others, 
  it 
  does 
  not 
  appear 
  to 
  present 
  particular 
  affinities 
  

   with 
  any 
  one 
  yet 
  made 
  known. 
  The 
  large 
  size 
  of 
  the 
  tail, 
  

   together 
  with 
  the 
  prominence 
  and 
  almost 
  denticulate 
  arma- 
  

   ture 
  of 
  its 
  keels, 
  not 
  to 
  mention 
  the 
  long 
  hairs 
  which 
  adorn 
  

   it, 
  are 
  perhaps 
  the 
  most 
  noticeable 
  of 
  its 
  features. 
  In 
  the 
  

   form 
  of 
  these 
  keels 
  may 
  be 
  seen 
  an 
  approximation 
  to 
  the 
  high 
  

   compressed 
  keels 
  which 
  characterize 
  those 
  Buthidaj 
  belonging 
  

   to 
  the 
  so-called 
  genus 
  Androctonus.

   the

  synonyms 
  appertaining 
  to

  liosoma 
  of

   berg 
  ; 
  but 
  scarcely 
  rightly 
  I 
  think. 
  For, 
  in 
  addition 
  to 
  some 
  

   Arabian 
  and 
  several 
  East-African 
  specimens 
  of 
  a 
  species 
  of 
  

   Scorpion 
  which 
  are 
  undoubtedly 
  referable 
  to 
  B. 
  liosoma.
