  The 
  conclusion 
  of 
  the 
  diagnosis 
  of 
  this 
  species 
  is 
  as 
  fol- 
  

   lows 
  : 
  — 
  "An 
  forsitan 
  masculum 
  tantum 
  Buthi 
  hottentottre 
  

   (Fabr.), 
  cum 
  qua 
  specie 
  magnam 
  similitudinem 
  habet 
  ; 
  sed 
  

   in 
  permullis 
  multorum 
  locorum 
  hujus 
  speciei 
  exemplis 
  a 
  me 
  

   visis 
  nullum 
  digiti 
  mobilis 
  palporum 
  lobo 
  illo 
  exstructum 
  

   est." 
  

  

  Possessing 
  but 
  one 
  male 
  specimen 
  wherewith 
  to 
  test 
  the 
  

   constancy 
  of 
  this 
  character, 
  Dr. 
  Karsch 
  was 
  left 
  in 
  doubt 
  

   as 
  to 
  the 
  validity 
  of 
  the 
  species 
  described. 
  An 
  examination, 
  

   however, 
  of 
  the 
  specimens 
  of 
  Buthus 
  contained 
  in 
  the 
  British 
  

   Museum 
  has 
  shown 
  that 
  B. 
  Martensii 
  is 
  distinct 
  from 
  B. 
  

   hottentotta 
  and 
  that 
  the 
  two 
  may 
  be 
  readily 
  separated 
  by 
  the 
  

   following 
  features 
  :
