  Mr. 
  II. 
  C. 
  Burnup 
  on 
  South- 
  African 
  

  

  as 
  the 
  uppermost 
  of 
  four 
  i( 
  palatal 
  " 
  processes 
  is 
  much 
  in 
  the 
  

   same 
  position 
  as 
  that 
  which 
  I 
  consider 
  a 
  second, 
  or 
  lower, 
  

   parietal 
  plait. 
  Although, 
  since 
  (in 
  the 
  varieties 
  at 
  any 
  rate) 
  

   the 
  process 
  in 
  question 
  arises 
  on 
  its 
  one 
  side 
  high 
  on 
  the 
  

   callus 
  on 
  the 
  body-whorl, 
  and 
  on 
  its 
  other 
  side 
  on 
  the 
  lobe 
  

   of 
  the 
  labrum, 
  it 
  is 
  conceivable 
  that 
  one 
  student 
  might 
  con- 
  

   sider 
  it 
  a 
  parietal, 
  while 
  another 
  treated 
  it 
  as 
  a 
  labral 
  plait 
  ; 
  

   yet 
  I 
  think 
  there 
  can 
  be 
  no 
  doubt 
  that 
  it 
  is 
  (in 
  the 
  varieties) 
  

   at 
  least 
  the 
  homologue 
  of 
  the 
  second 
  parietal 
  plait 
  to 
  be 
  found 
  

   in 
  all 
  other 
  members 
  of 
  Ancey's 
  section 
  Anisoloma. 
  

  

  The 
  var. 
  tomlini, 
  then, 
  should 
  be 
  easily 
  distinguished 
  from 
  

   the 
  type 
  by 
  this 
  plait 
  being 
  less 
  strongly 
  developed, 
  and 
  by 
  

   the 
  presence 
  of 
  a 
  narrow 
  perforation 
  and 
  a 
  basal 
  plait, 
  absent 
  

   from 
  the 
  type. 
  

  

  24. 
  Pupa 
  (Fauxulus) 
  mcbeaniana 
  (M, 
  & 
  P.). 
  

   (PI. 
  X. 
  fig. 
  8.) 
  

  

  This 
  striking 
  shell, 
  larger 
  than 
  the 
  preceding 
  species 
  and 
  

   its 
  varieties, 
  may 
  be 
  horn-coloured, 
  greyish-brown, 
  or 
  mil 
  It 
  - 
  

   unite. 
  Normally 
  this 
  species 
  has 
  nine 
  peristomatal 
  processes, 
  

   viz. 
  two 
  parietal, 
  two 
  columellar, 
  one 
  basal, 
  and 
  four 
  labral, 
  of 
  

   which 
  last 
  named 
  the 
  lowest 
  is 
  large, 
  the 
  central 
  small, 
  and 
  

   above 
  this, 
  in 
  the 
  sinus 
  of 
  the 
  labrum, 
  are 
  two, 
  very 
  small 
  

   and 
  close 
  together. 
  In 
  the 
  type, 
  which 
  is 
  not 
  available 
  to 
  

   me 
  for 
  examination, 
  these 
  two 
  small 
  plaits 
  may 
  be 
  merged 
  

   into 
  one 
  broad 
  plait, 
  as 
  in 
  the 
  case 
  of 
  a 
  shell 
  from 
  Inhluzani 
  

   Mountain, 
  in 
  my 
  collection 
  ; 
  for 
  the 
  authors 
  do 
  not 
  refer 
  to 
  

   a 
  pair, 
  nor 
  does 
  the 
  original 
  figure 
  show 
  it. 
  One 
  shell 
  in 
  

   my 
  collection, 
  also 
  from 
  Inhluzani, 
  bears 
  an 
  additional 
  plait 
  

   at 
  the 
  base 
  of 
  the 
  columella 
  ; 
  but 
  as 
  it 
  is 
  only 
  one 
  example 
  

   in 
  many, 
  and 
  is 
  otherwise 
  normal, 
  it 
  must 
  only 
  be 
  looked 
  

   upon 
  as 
  a 
  sport. 
  

  

  As 
  the 
  original 
  figure 
  is 
  very 
  deficient 
  in 
  the 
  detail 
  of 
  the 
  

   peristomatal 
  processes, 
  a 
  new 
  figure, 
  drawn 
  from 
  a 
  shell 
  in 
  

   my 
  collection, 
  collected 
  at 
  Dargle, 
  is 
  published 
  herewith. 
  

  

  The 
  dimensions 
  of 
  the 
  figured 
  specimen 
  are 
  as 
  follows 
  : 
  — 
  

  

  Height 
  4-5, 
  width 
  2*58 
  mm. 
  

  

  25. 
  Pupa 
  (Fauxulus) 
  piamphorodon 
  (Benson). 
  

  

  This 
  species 
  seems 
  very 
  variable 
  as 
  to 
  size, 
  the 
  type 
  mea- 
  

   suring 
  9 
  mm. 
  high 
  and 
  4 
  wide, 
  while 
  the 
  only 
  specimen 
  that 
  

   1 
  have 
  measured 
  accurately 
  is 
  7*5 
  mm. 
  high 
  and 
  3*75 
  wide.
