  I 
  am 
  not 
  quite 
  satistied 
  about 
  the 
  identification 
  of 
  this 
  species, 
  

   which 
  occurred 
  in 
  Mr. 
  Townsend's 
  earliest 
  gatherings 
  at 
  Karachi, 
  but 
  

   has 
  not 
  been 
  met 
  with 
  since. 
  It 
  may 
  be

   lleeve

  not

   "

  it

  also

  This 
  large 
  and 
  conspicuous 
  species 
  is 
  rare 
  in 
  its 
  only 
  known 
  locality, 
  

   and 
  has 
  not 
  yet 
  been 
  found 
  excepting 
  in 
  rather 
  worn 
  condition. 
  It 
  

   is 
  44 
  to 
  45 
  mm. 
  in 
  length 
  by 
  16 
  in 
  breadth. 
  It 
  seems 
  undoubtedly 
  

   a 
  member 
  of 
  the 
  sub-genus 
  Tylotia.

  Some 
  of 
  our 
  examples 
  exceed 
  the 
  specimen 
  figured 
  by

  and 
  

   others 
  possess 
  a 
  darkish 
  slate-coloured 
  fascia 
  around 
  the 
  centre 
  of 
  the 
  

   body-whorl, 
  but 
  otherwise 
  the 
  species 
  does 
  not 
  vary 
  much. 
  Till 
  

   recently 
  the 
  locality 
  was 
  unknown. 
  A 
  fine 
  example 
  I 
  possess, 
  which 
  

   was 
  received

  There 
  is

  the 
  two 
  or 
  three 
  examples 
  

   recorded 
  from 
  the

  They 
  were 
  not 
  very

  of 
  this
