  It 
  is 
  not 
  phcedimus. 
  for 
  tlie 
  apical 
  coils 
  of 
  tliat 
  species 
  are 
  

   dark 
  hrown, 
  no 
  white 
  at 
  all;

   with

  Animal 
  is 
  pale 
  throughout, 
  vo 
  spotting 
  on 
  the 
  vmceral 
  

   sac; 
  when 
  first 
  looked 
  at 
  the 
  colouring 
  ot 
  tlie 
  animal 
  recalls 
  

   that 
  of 
  Peltattis 
  pondoensis 
  ;

  of

  dark 
  

   broivn 
  liver 
  and 
  white 
  ypper 
  surface 
  of 
  the 
  apical 
  coils 
  and 
  

   the 
  form 
  of 
  the 
  shell-lobes 
  at 
  once 
  distinguish 
  this 
  species 
  

   from 
  the 
  Pondoland 
  one. 
  The 
  value 
  of 
  drawings 
  over 
  

   description 
  to 
  show 
  differences 
  of 
  this 
  nature 
  is 
  illustrated 
  

   in 
  this 
  instance. 
  The 
  lobe 
  over 
  the 
  mucous 
  pore 
  (tig. 
  2 
  b) 
  

   is 
  moderately 
  large. 
  The 
  right 
  shell-lobe 
  (iig. 
  2) 
  is 
  long 
  

   and 
  broad, 
  the 
  lelt 
  (fig. 
  2) 
  elongate 
  and 
  triangular, 
  on 
  a 
  

   wide 
  base 
  of 
  the 
  mantle-edge. 
  In 
  the 
  drawing 
  it 
  is 
  shown 
  

   drooping 
  over, 
  not 
  in 
  its 
  natural 
  position, 
  turned 
  over 
  the 
  

   edge 
  of 
  the 
  peristome 
  and 
  lying 
  on 
  the 
  surface 
  of 
  the 
  shell. 
  

  

  In 
  the 
  generative 
  organs 
  (PI. 
  XX. 
  fig. 
  1) 
  the 
  penis 
  has 
  a 
  

   long 
  ffagellum, 
  which 
  towards 
  the 
  free 
  end 
  bifurcates 
  into 
  

   two 
  distinct 
  branches. 
  These 
  are 
  to 
  be 
  explained 
  by 
  a 
  

   reference 
  to 
  the 
  figures 
  of 
  spermatophores 
  on 
  pi. 
  iii, 
  fig. 
  1 
  b), 
  

   Avhere 
  the 
  usually 
  single 
  wliip-like 
  end 
  has 
  another 
  and 
  a 
  

   finer 
  one. 
  Experience 
  when 
  dissecting 
  has 
  shown 
  me 
  this 
  

   is 
  very 
  easily 
  broken 
  off". 
  

  

  The 
  epiphallus 
  is 
  very 
  long 
  in 
  this 
  species, 
  the 
  short 
  

   accessory 
  organ 
  being 
  given 
  oft" 
  nearer 
  to 
  the 
  retractor 
  

   muscle 
  than 
  to 
  the 
  vas 
  deferens. 
  The 
  spermatheca 
  is 
  on 
  a 
  

   long 
  stalk", 
  and, 
  being 
  empty, 
  was 
  more 
  elongately 
  pear- 
  

   shaped.
