  These 
  varietal 
  names 
  seem 
  scarcely 
  worth 
  perpetuating, 
  as 
  

   all 
  intermediate 
  forms, 
  as 
  well 
  as 
  other 
  forms 
  with 
  attributes 
  

   of 
  equal 
  varietal 
  value, 
  exist.

  2.3. 
  Pupa 
  {Fauxulus) 
  glanvilleana 
  (Ancey). 
  

  

  As 
  Mr. 
  Ancey 
  described 
  this 
  shell 
  very 
  carefully 
  and 
  with 
  

   close 
  attention 
  to 
  detail 
  in 
  order 
  that 
  it 
  might 
  be 
  recognized 
  

   from 
  description 
  alone 
  without 
  the 
  help 
  of 
  a 
  figure, 
  it 
  may 
  

   be 
  taken 
  for 
  granted 
  that 
  no 
  important 
  feature 
  was 
  omitted 
  

   from 
  his 
  diagnosis. 
  It 
  therefore 
  appears 
  to 
  me 
  that 
  Melvill 
  

   and 
  Ponsonby 
  erred 
  in 
  choosing 
  the 
  figure 
  of 
  my 
  shell, 
  found 
  

   at 
  Dargle, 
  Natal, 
  to 
  illustrate 
  Ancey's 
  species 
  in 
  their 
  Survey, 
  

   for 
  that 
  shell 
  does 
  not 
  by 
  any 
  means 
  closely 
  agree 
  with 
  

   Ancey's 
  description, 
  being 
  shorter 
  and 
  wider 
  than 
  the 
  typical 
  

   glanvilleana, 
  and 
  possessing 
  two 
  plaits 
  on 
  the 
  base 
  of 
  the 
  

   peristome 
  not 
  mentioned 
  in 
  Ancey's 
  description, 
  besides 
  

   showing 
  other 
  discrepancies. 
  I 
  cannot 
  but 
  doubt 
  if 
  the 
  two 
  

   forms 
  belong 
  to 
  one 
  species, 
  but 
  in 
  our 
  present 
  ignorance 
  as 
  

   to 
  what 
  Ancey's 
  shell 
  really 
  is 
  through 
  no 
  figure 
  having 
  been 
  

   published 
  with 
  his 
  description, 
  and 
  the 
  type 
  not 
  being 
  avail- 
  

   able 
  for 
  reference, 
  it 
  is 
  impossible 
  to 
  estimate 
  exactly 
  the 
  

   extent 
  of 
  the 
  divergence, 
  so 
  I 
  have 
  deemed 
  it 
  best 
  tentatively 
  

   to 
  treat 
  the 
  Dargle 
  shell 
  as 
  a 
  variety 
  of 
  glanvilleana, 
  with 
  

   which 
  it 
  seems 
  to 
  have 
  much 
  in 
  common. 
  

  

  * 
  If 
  B. 
  B. 
  Woodward's 
  arrangement 
  be 
  followed, 
  Papilla 
  becomes 
  the 
  

   subgen. 
  Janimia 
  (s. 
  s.).
