  Papuina 
  Hedleti, 
  Smith. 
  

  

  Mr. 
  Smith 
  has 
  already 
  mentioned 
  (Ann. 
  Mag. 
  Nat. 
  Hist., 
  1897, 
  

   ser. 
  Ti, 
  vol. 
  XX, 
  p. 
  414) 
  that 
  this 
  species 
  is 
  rather 
  variable 
  in 
  colour, 
  

   and 
  this 
  observation 
  is 
  amply 
  borne 
  out 
  by 
  the 
  series 
  now 
  obtained, 
  

   the 
  specimens 
  ranging 
  from 
  pale 
  ochraceous 
  to 
  buff 
  and 
  dark, 
  almost 
  

   blackish, 
  brown, 
  some 
  of 
  the 
  paler 
  shells 
  having 
  a 
  pale 
  base 
  and 
  

   pinkish 
  peristome, 
  while 
  others 
  have 
  a 
  pale 
  base 
  with 
  dark-brown, 
  

   narrowly 
  margined 
  peristome, 
  and 
  another 
  has 
  the 
  base 
  blackish 
  

   brown 
  and 
  a 
  corresponding 
  dark, 
  broadly 
  margined 
  peristome. 
  All 
  

   dark 
  specimens, 
  however, 
  are 
  characterized 
  by 
  a 
  dark 
  base. 
  

  

  In 
  every 
  case 
  the 
  columella 
  has 
  a 
  more 
  or 
  less 
  prominent 
  whitish 
  

   thickening 
  which 
  in 
  some 
  specimens 
  bears 
  a 
  tooth 
  or 
  tubercle. 
  All 
  

   are 
  encircled 
  with 
  numerous 
  narrow, 
  opaque-white, 
  spiral 
  bands, 
  

   which 
  on 
  the 
  earlier 
  whorls 
  are 
  continuous, 
  but 
  lower 
  down 
  become 
  

   interrupted 
  by 
  the 
  oblique 
  lines 
  of 
  growth, 
  and 
  disappear 
  on 
  the 
  

   penultimate 
  or 
  last 
  whorl, 
  but 
  in 
  one 
  instance 
  reaching 
  right 
  up 
  to 
  

   the 
  peristome, 
  faint 
  traces 
  being 
  also 
  observable 
  on 
  the 
  base 
  in 
  some. 
  

   The 
  narrow 
  band 
  bordering 
  the 
  keel 
  on 
  both 
  sides 
  also 
  varies 
  from 
  

   opaque 
  pale 
  ochraceous 
  to 
  yellow 
  in 
  the 
  paler 
  shells, 
  and 
  dark 
  

   orange 
  in 
  the 
  darker 
  specimens. 
  The 
  species 
  has 
  hitherto 
  been 
  only 
  

   recorded 
  from 
  South- 
  West 
  New 
  Guinea. 
  

  

  Papuina 
  Beauforti, 
  Bavay. 
  

   Helix 
  {Papuina) 
  Beauforti, 
  Bavay, 
  Nova 
  Guinea, 
  1908,

   As 
  already 
  observed 
  by 
  Mons. 
  Bavay, 
  this 
  species 
  is 
  allied 
  to 
  

   euconus, 
  Mlldff., 
  but 
  it 
  has 
  a 
  broader 
  base, 
  more 
  convex 
  whorls, 
  and 
  

   a 
  concave 
  spire, 
  while 
  the 
  spirals 
  on 
  the 
  last 
  whorl 
  and 
  the 
  base 
  (to 
  

   which, 
  by 
  the 
  way, 
  no 
  reference 
  is 
  made) 
  are 
  much 
  finer 
  and 
  closer. 
  

   Mollendorff 
  placed 
  his 
  species 
  in 
  Satsuma 
  [= 
  Oanesella'], 
  but, 
  although 
  

   both 
  this 
  and 
  the 
  new 
  species 
  lack 
  the 
  wrinkled 
  sculpture 
  peculiar 
  

   to 
  most 
  species 
  of 
  Papuina, 
  they 
  possess 
  some 
  features 
  in 
  common 
  

   with 
  the 
  group 
  of 
  P. 
  Hedleyi 
  — 
  which 
  is, 
  moreover, 
  also 
  devoid 
  of 
  

   wrinkles 
  — 
  i.e. 
  the 
  peculiar 
  manner 
  in 
  which 
  the 
  columellar 
  margin 
  

   of 
  the 
  peristome 
  covers 
  the 
  narrow 
  perforation 
  of 
  the 
  umbilicus, 
  

   leaving 
  only 
  a 
  very 
  narrow 
  oblique 
  slit, 
  and 
  the 
  extension 
  of 
  the 
  

   parietal 
  callus 
  beyond 
  the 
  umbilical 
  region. 
  The 
  close, 
  minute 
  

   spirals, 
  the 
  pyramidal 
  form, 
  and 
  the 
  appearance 
  of 
  the 
  nepionic 
  

   whorls 
  still 
  further 
  connect 
  them 
  with 
  this 
  group, 
  and 
  these 
  con- 
  

   siderations 
  appear 
  to 
  me 
  to 
  warrant 
  their 
  inclusion 
  in 
  Papuina. 
  One 
  

   specimen 
  was 
  collected.

  Three 
  specimens, 
  one 
  more 
  elevated 
  in 
  the 
  spire 
  and 
  with 
  wider, 
  

   less 
  covered 
  umbilicus 
  than 
  the 
  type, 
  and 
  without 
  peripheral 
  band.

  Mr. 
  Smith, 
  in 
  describing 
  this 
  species, 
  ventures 
  the 
  opinion 
  that 
  it 
  is 
  

   perhaps 
  only 
  a 
  variety 
  of 
  P. 
  lituus 
  or 
  P. 
  labium. 
  It 
  appears 
  to 
  me, 
  

   however, 
  to 
  be 
  quite 
  entitled 
  to 
  specific 
  rank, 
  being 
  more 
  conical 
  in
