  Mr. 
  H. 
  C. 
  Bumup 
  on 
  South- 
  African 
  

  

  I 
  am 
  particularly 
  indebted 
  to 
  Mr. 
  Ponsonby 
  for 
  the 
  patient 
  

   care 
  with 
  which 
  he, 
  during 
  a 
  recent 
  visit 
  to 
  South 
  Africa, 
  

   discussed 
  the 
  Survey 
  with 
  me, 
  and 
  encouraged 
  me 
  to 
  publish 
  

   the 
  emendments 
  and 
  additions 
  to 
  be 
  found 
  in 
  the 
  present 
  

   revision. 
  

  

  Although 
  Mr. 
  Woodward's 
  arguments 
  in 
  favour 
  of 
  the 
  

   supercession 
  of 
  (he 
  name 
  Pupa, 
  Diap., 
  by 
  Jaminia, 
  Risso 
  *, 
  

   seem 
  to 
  me 
  quite 
  convincing, 
  I 
  have 
  in 
  the 
  following 
  

   notes 
  and 
  descriptions, 
  for 
  the 
  sake 
  of 
  convenience 
  in 
  

   reference, 
  adhered 
  as 
  far 
  as 
  possible 
  to 
  Melvill 
  and 
  Ponsonby's 
  

   nomenclature. 
  

  

  1. 
  Pupa 
  crawfordiana 
  (M. 
  & 
  P.). 
  

   (PI. 
  X. 
  figs. 
  1, 
  2.) 
  

  

  Melvill 
  and 
  Ponsonby 
  say 
  of 
  this 
  species: 
  "Allied 
  to 
  

   P. 
  layardi, 
  Bens." 
  ; 
  but 
  it 
  is 
  easily 
  distinguishable 
  by 
  its 
  

   stouter 
  form, 
  less 
  ventricose 
  whorls, 
  shallower 
  sutures, 
  more 
  

   regularly 
  conical 
  spire, 
  less 
  mammillated 
  apex, 
  rather 
  

   smoother 
  surface, 
  less 
  effuse 
  peristome, 
  and 
  by 
  the 
  absence 
  of 
  

   the 
  seventh, 
  minute, 
  plait 
  to 
  be 
  seen, 
  in 
  P. 
  layardi, 
  at 
  the 
  

   junction 
  of 
  the 
  parietal 
  wall 
  with 
  the 
  columella. 
  The 
  arrange- 
  

   ment 
  of 
  the 
  other 
  peristomatal 
  processes 
  is 
  practically 
  iden- 
  

   tical 
  in 
  both 
  species. 
  

  

  The 
  original 
  figure 
  is 
  defective 
  in 
  form 
  and 
  deficient 
  in 
  

   detail, 
  so 
  I 
  herewith 
  offer 
  new 
  figures 
  drawn 
  from 
  the 
  co-type 
  

   in 
  Mr. 
  Ponsonby's 
  collection, 
  kindly 
  lent 
  to 
  me 
  for 
  the 
  

   purpose. 
  Mr. 
  Ponsonby 
  has 
  compared 
  my 
  figures 
  with 
  the 
  

   type 
  in 
  the 
  British 
  Museum, 
  and 
  finds 
  that 
  they 
  correspond 
  

   accurately, 
  except 
  that 
  the 
  callus 
  in 
  the 
  type 
  is 
  not 
  chipped 
  

   as 
  in 
  the 
  co-type, 
  so 
  verifying 
  that 
  part 
  of 
  the 
  original 
  

   description 
  recording 
  the 
  peristome 
  as 
  continuous. 
  Of 
  the 
  

   co-type 
  it 
  would 
  be 
  more 
  accurate 
  to 
  say 
  that 
  the 
  ends 
  of 
  the 
  

   peristome 
  converge 
  and 
  are 
  connected 
  by 
  a 
  callus. 
  A 
  com- 
  

   parison 
  of 
  fig. 
  2 
  with 
  fig. 
  4 
  well 
  illustrates 
  the 
  difference 
  in 
  

   profuseness 
  of 
  peristome.
