  8. 
  Pupa 
  griqualandica, 
  M. 
  & 
  P. 
  

  

  This 
  species 
  must 
  be 
  closely 
  akin 
  to 
  P. 
  bisulcata, 
  Jick., 
  

   from 
  Abyssinia, 
  judging 
  alone 
  from 
  description 
  and 
  figure, 
  

   for 
  I 
  have 
  not 
  been 
  able 
  to 
  examine 
  the 
  type 
  or 
  authenticated 
  

   specimens 
  of 
  Jickeli's 
  species. 
  Mr. 
  Ponsonby 
  has, 
  however, 
  

   very 
  kindly 
  examined 
  for 
  me 
  the 
  specimens 
  in 
  the 
  British 
  

   Museum 
  bearing 
  that 
  name, 
  in 
  conjunction 
  with 
  specimens 
  

   of 
  griqualandica, 
  and, 
  while 
  finding 
  them 
  " 
  very 
  similar," 
  

   pronounced 
  them 
  to 
  be 
  " 
  at 
  once 
  separable," 
  basing 
  the 
  

   separation 
  apparently 
  mainly 
  upon 
  the 
  presence 
  of 
  " 
  a 
  large 
  

   prominent 
  tooth 
  on 
  the 
  outer 
  lip" 
  of 
  bisulcata. 
  This 
  tooth 
  or 
  

   plait, 
  if 
  not 
  so 
  large, 
  is 
  also 
  present 
  in 
  griqualandica, 
  though, 
  

   perhaps 
  through 
  being 
  in 
  shadow, 
  is 
  not 
  so 
  conspicuous 
  in 
  

   the 
  figures 
  chosen 
  by 
  Melvill 
  and 
  Ponsonby 
  to 
  illustrate 
  their 
  

   specit-s 
  as 
  in 
  Jickeli's 
  figure. 
  No 
  mention 
  is 
  made 
  in 
  Melvill 
  

   and 
  Ponsonby's 
  description 
  of 
  the 
  two 
  sulci 
  on 
  the 
  outer 
  lip 
  

   (corresponding 
  with 
  the 
  labral 
  plaits) 
  to 
  be 
  discerned 
  in 
  

   griqualandica 
  as 
  represented 
  in 
  the 
  figure 
  of 
  bisulcata. 
  On 
  

   the 
  other 
  hand, 
  Jickeli 
  does 
  not 
  record 
  the 
  presence 
  of 
  the 
  

   sixth, 
  minute, 
  internal 
  basal 
  plait 
  " 
  visible 
  in 
  some 
  specimens," 
  

   which 
  appears 
  to 
  me 
  to 
  be 
  a 
  constant 
  character 
  of 
  griqua- 
  

   landica, 
  though 
  it 
  is 
  easily 
  overlooked 
  owing 
  to 
  its 
  extreme 
  

   smallness 
  and 
  internal 
  position. 
  The 
  dimensions 
  given 
  by 
  

   Jickeli 
  represent 
  a 
  considerably 
  larger 
  and 
  comparatively 
  

   narrower 
  shell 
  than 
  griqualandica, 
  but, 
  as 
  they 
  do 
  not 
  corre- 
  

   spond 
  with 
  the 
  proportions 
  of 
  his 
  figure, 
  one 
  or 
  other 
  must 
  

   be 
  wrong 
  — 
  so 
  neither 
  is 
  reliable. 
  If 
  his 
  figure 
  actually 
  repre- 
  

   sents 
  a 
  shell 
  of 
  If 
  mm. 
  in 
  height, 
  its 
  width 
  is 
  1'27 
  instead 
  of 
  

   1 
  mm. 
  as 
  he 
  states. 
  

  

  The 
  dimensions 
  of 
  the 
  shells 
  figured 
  in 
  Melvill 
  and 
  Pon- 
  

   sonby's 
  paper 
  are 
  as 
  follows 
  :

  The 
  average 
  of 
  twenty-one 
  specimens 
  measured 
  by 
  me 
  is 
  : 
  — 
  

   Height 
  1*53, 
  width 
  0*87 
  mm., 
  the 
  largest 
  being 
  height 
  1*6, 
  

   width 
  0'99 
  mm.
