  Typographical

  necessary. 
  

  

  Shell 
  minute, 
  rimate, 
  subcylindrical, 
  elliptical, 
  thin, 
  trans- 
  

   lucent, 
  shining, 
  very 
  pale 
  brown; 
  spire 
  elongate-turbinate, 
  

   with 
  greatest 
  width 
  at 
  the 
  fourth 
  whorl 
  ; 
  sutures 
  rather 
  

   deeply 
  impressed, 
  apex 
  very 
  obtuse 
  ; 
  whorls 
  5^-, 
  very 
  convex, 
  

   closely 
  transversely 
  striate, 
  excepting 
  the 
  first 
  1^, 
  which 
  are 
  

   smooth, 
  the 
  last 
  compressed 
  round 
  the 
  umbilical 
  region 
  ; 
  

   aperture 
  nearly 
  erect, 
  rounded, 
  nearly 
  £ 
  the 
  height 
  of 
  the 
  

   shell. 
  Peristome 
  slightly 
  thickened 
  and 
  reflexed, 
  more 
  so 
  at 
  

   the 
  columella! 
  - 
  margin, 
  scarcely 
  paler 
  than 
  the 
  rest 
  of 
  the 
  

   shell, 
  with 
  labrum 
  slightly 
  straightened 
  about 
  the 
  middle 
  and 
  

   much 
  receding 
  towards 
  the 
  base 
  ; 
  columella 
  arcuate. 
  The 
  

   only 
  tooth, 
  conspicuous, 
  white, 
  rounded, 
  and 
  remote, 
  is 
  

   situate 
  inside, 
  about 
  midway 
  between 
  the 
  last 
  suture 
  and 
  the 
  

   base 
  and 
  about 
  half 
  a 
  turn 
  from 
  the 
  labrum.

  Hab. 
  Pretoria 
  (Farquhar

  Major 
  Connolly 
  

   has 
  since 
  supplied 
  me 
  with 
  many 
  specimens, 
  quite 
  agreeing 
  

   with 
  the 
  type, 
  from 
  the 
  same 
  locality. 
  

  

  The 
  following 
  are 
  the 
  dimensions 
  of 
  the 
  largest 
  and 
  

   smallest 
  adult 
  specimens 
  measured 
  :

  Largest 
  : 
  height 
  151, 
  width 
  0*80. 
  

  

  Smallest: 
  „ 
  1*32, 
  „ 
  075. 
  

  

  This 
  is 
  the 
  smallest 
  of 
  the 
  South-African 
  group 
  examined 
  

   by 
  me, 
  and 
  is 
  of 
  a 
  paler 
  colour 
  than 
  most. 
  As 
  compared 
  

   with 
  P. 
  perple.va, 
  which 
  seems 
  to 
  be 
  its 
  nearest 
  ally, 
  it 
  is 
  

   smaller, 
  smoother, 
  paler, 
  and 
  less 
  cylindrical, 
  is 
  only 
  rimate 
  

   instead 
  of 
  umbilicate, 
  has 
  the 
  peristome 
  less 
  reflexed, 
  and 
  is 
  

   destitute 
  of 
  the 
  postcolumellar 
  and 
  parietal 
  plaits. 
  As 
  com- 
  

   pared 
  with 
  dysorata, 
  of 
  which 
  intradentata 
  appears 
  in 
  the 
  

   Survey 
  as 
  a 
  variety, 
  it 
  is 
  smaller, 
  more 
  slender, 
  paler, 
  less 
  

   cylindrical, 
  more 
  loosely 
  coiled, 
  with 
  more 
  ventricose 
  whorls 
  

   and 
  deeper 
  sutures, 
  and 
  is 
  rimate 
  instead 
  of 
  umbilicate 
  ; 
  the 
  

   aperture 
  is 
  smaller 
  and 
  rounder, 
  receding 
  more 
  at 
  the 
  base, 
  

   and 
  is 
  furnished 
  with 
  a 
  tooth 
  in 
  the 
  gullet, 
  not 
  found 
  in 
  

   dysorata. 
  

  

  I 
  am 
  indebted 
  to 
  Mr. 
  Ponsonby 
  for 
  making 
  a 
  careful 
  

   comparison 
  between 
  Mr. 
  Sykes's 
  type 
  of 
  dysorata 
  and 
  the 
  

   type 
  of 
  intradentata 
  in 
  the 
  British 
  Museum, 
  when 
  he 
  was 
  

   able 
  to 
  confirm 
  most 
  of 
  the 
  details 
  given 
  above.
