  There 
  seems 
  little, 
  if 
  any, 
  reason 
  to 
  doubt 
  the 
  justice 
  of 
  

   Bcettger's 
  discrimination 
  in 
  placing 
  P. 
  ovampoensis, 
  M. 
  & 
  P., 
  

   in 
  the 
  synonymy 
  of 
  this 
  species, 
  as 
  Ancey's 
  description 
  

   conveys 
  a 
  faithful 
  image 
  of 
  the 
  shell 
  known 
  to 
  South-African 
  

   collectors 
  as 
  P. 
  ovampoensis 
  ; 
  but 
  it 
  must 
  not 
  be 
  lost 
  sight 
  of 
  

   that 
  1£ 
  mm., 
  Ancey's 
  width 
  dimension, 
  seems 
  excessive, 
  1mm. 
  

   being 
  the 
  greatest 
  width 
  that 
  I 
  have 
  observed 
  with 
  a 
  height 
  

   corresponding 
  to 
  that 
  of 
  Ancey's 
  type, 
  though 
  in 
  one 
  very 
  

   large 
  specimen 
  in 
  my 
  collection 
  from 
  Johannesburg 
  (McBean) 
  , 
  

   whose 
  height 
  is 
  2*5 
  mm., 
  the 
  width 
  almost 
  equals 
  Ancey's 
  

   measurement, 
  being 
  I'll 
  mm. 
  

  

  The 
  figure 
  chosen 
  by 
  Melv. 
  & 
  Pons, 
  to 
  represent 
  their 
  

   species 
  in 
  the 
  Survey 
  is 
  that 
  of 
  the 
  lirate 
  var. 
  from 
  Rusten- 
  

   berg 
  (McBean), 
  which 
  shows 
  more 
  sculpture 
  than 
  the 
  normal 
  

   form, 
  but 
  agrees 
  in 
  other 
  respects. 
  The 
  shell 
  figured 
  

   measures 
  2'25 
  mm. 
  high 
  and 
  1 
  mm. 
  wide.

  Pupa 
  dysorata, 
  M. 
  & 
  P. 
  

  

  The 
  emended 
  description 
  given 
  in 
  the 
  Survey 
  has 
  

   become 
  somewhat 
  involved, 
  owing 
  apparently 
  to 
  two 
  causes, 
  

   viz., 
  firstly, 
  to 
  the 
  authors 
  having 
  included 
  intradenlata 
  as 
  a 
  

   var. 
  of 
  this 
  species 
  (with 
  which 
  1 
  cannot 
  agree) 
  and 
  their 
  

   desire 
  to 
  differentiate 
  the 
  typical 
  form, 
  in 
  its 
  description, 
  

   from 
  its 
  supposed 
  var. 
  ; 
  and, 
  secondly, 
  to 
  their 
  having 
  mis- 
  

   understood 
  the 
  position 
  of 
  the 
  "deep-seated 
  postlabial* 
  tooth 
  " 
  

   of 
  intradentata, 
  treating 
  it 
  as 
  a 
  columellar 
  process 
  instead 
  of 
  

   one 
  situate 
  " 
  in 
  the 
  gullet." 
  In 
  addition 
  to 
  this, 
  my 
  measure- 
  

   ment 
  of 
  the 
  type, 
  kindly 
  lent 
  to 
  me 
  by 
  Mr. 
  E. 
  R. 
  Sykes, 
  is 
  

  

  * 
  Perhaps 
  the 
  common 
  expression 
  " 
  labial," 
  used 
  to 
  express 
  pertaining 
  

   to 
  any 
  part 
  of 
  the 
  peristome 
  or 
  lip, 
  is 
  confusing, 
  and 
  lubral 
  would 
  be 
  

   better 
  when 
  the 
  position 
  wished 
  to 
  be 
  indicated 
  pertains 
  to 
  the 
  labrum,
