  the 
  exact 
  counterpart 
  of 
  the 
  one 
  now 
  under 
  consideration. 
  The 
  label 
  

   bears 
  the 
  original 
  inscription, 
  '■' 
  H. 
  euchroes, 
  var.," 
  which 
  was 
  after- 
  

   wards 
  deleted, 
  and 
  lenta 
  substituted. 
  At 
  first 
  I 
  was 
  inclined 
  to 
  

   consider 
  my 
  shell 
  to 
  be 
  Pfeiiier's 
  euchroes, 
  but 
  in 
  spite 
  of 
  the 
  fact 
  that 
  

   it 
  is 
  of 
  larger 
  size 
  — 
  measuring, 
  diam. 
  maj. 
  35, 
  min. 
  28 
  mm.; 
  alt. 
  

   38 
  mm. 
  — 
  and 
  has, 
  moreover, 
  the 
  spire 
  relatively 
  higher 
  than 
  lenta, 
  the 
  

   balance 
  of 
  evidence 
  appears 
  to 
  me 
  in 
  favour 
  of 
  its 
  being 
  co-specific 
  

   with 
  the 
  latter 
  species. 
  PfeiiSer, 
  in 
  his 
  original 
  description 
  (Malak. 
  

   Blatter, 
  1854, 
  vol. 
  i, 
  p. 
  57), 
  quotes 
  the 
  figure 
  of 
  H. 
  pileus, 
  var., 
  in 
  

   Conch. 
  Cab., 
  Helix, 
  Abth. 
  i, 
  pi. 
  xl, 
  fig. 
  5, 
  which 
  also 
  has 
  a 
  higher 
  

   spire, 
  a 
  circumstance 
  adding 
  further 
  weight 
  to 
  my 
  conclusion. 
  

  

  The 
  exact 
  habitat 
  of 
  this 
  species 
  has 
  hitherto 
  remained 
  unknown, 
  

   the 
  Moluccas 
  having 
  been 
  doubtfully 
  indicated 
  as 
  the 
  original 
  locality 
  

   (Pfeiffer, 
  Mon. 
  Helic. 
  Yiv., 
  vol. 
  iv, 
  p. 
  257). 
  

  

  Papuina 
  khodochila, 
  n.sp. 
  Figs. 
  1-3. 
  

   Shell 
  sub-covered 
  perforate, 
  trochoidal, 
  ochraceous 
  brown, 
  becoming 
  

   paler 
  behind 
  the 
  peristome, 
  especially 
  on 
  the 
  base, 
  ornamented 
  with 
  

   a 
  very 
  narrow 
  dark-brown 
  supra-peripheral 
  band 
  visible 
  on 
  the 
  last 
  

   three 
  whorls, 
  finely 
  striated, 
  almost 
  ribbed 
  near 
  the 
  mouth, 
  and 
  

   showing 
  traces 
  of 
  excessively 
  fine 
  spirals 
  above, 
  very 
  minutely 
  and 
  

   closely 
  granulated 
  on 
  the 
  earlier 
  whorls, 
  the 
  granules 
  becoming 
  

   sparser 
  and 
  a 
  little 
  coarser 
  on 
  the 
  later 
  whorls, 
  while 
  on 
  the 
  base 
  

   they 
  are 
  elongated 
  in 
  the 
  direction 
  of 
  the 
  lines 
  of 
  growth 
  and 
  disposed 
  

   in 
  concentric 
  rows. 
  Spire 
  conical, 
  apex 
  prominent, 
  suture 
  shallow, 
  

   linear. 
  Whorls 
  5f 
  , 
  the 
  nepionic 
  convex, 
  the 
  later 
  ones 
  almost 
  flat, 
  

   except 
  the 
  last, 
  which 
  becomes 
  slightly 
  convex 
  and 
  dilated 
  towards 
  

   the 
  mouth, 
  is 
  convex 
  below, 
  becoming 
  tumid 
  towards 
  the 
  mouth 
  near 
  

   the 
  periphery, 
  slightly 
  and 
  slowly 
  descending 
  in 
  front, 
  with 
  an 
  acute 
  

  

  keel 
  slightly 
  pinched 
  on 
  the 
  upper 
  side, 
  and 
  slightly 
  exserted 
  as 
  far 
  

   as 
  the 
  second 
  whorl. 
  Aperture 
  obovate, 
  a 
  little 
  oblique, 
  margins 
  

   distant, 
  united 
  by 
  a 
  slight 
  callus 
  on 
  the 
  parietal 
  wall 
  ; 
  peristome 
  rosy, 
  

   a 
  little 
  thickened, 
  expanded 
  and 
  reflexed, 
  upper 
  margin 
  arched, 
  

   receding, 
  outer 
  rounded, 
  basal 
  slightly 
  curved, 
  columellar 
  strongly 
  

   reflexed, 
  ascending 
  obliquely 
  forward, 
  dilated 
  and 
  partly 
  covering 
  the 
  

   narrow 
  umbilicus. 
  Diam. 
  maj. 
  25,

  20'5

  mm. 
  

  

  Type 
  in 
  my 
  collection. 
  

  

  Represented 
  by 
  a 
  single 
  specimen. 
  No 
  nearly 
  related 
  species 
  from 
  

   New 
  Guinea 
  is 
  known, 
  but 
  in 
  shape 
  it 
  somewhat 
  resembles 
  the 
  

   variety 
  pyramidata 
  of 
  P. 
  pileolus, 
  Mts., 
  from 
  Batchian 
  ; 
  that 
  species, 
  

   however, 
  while 
  being 
  also 
  minutely 
  granulated, 
  possesses 
  several 
  well- 
  

   marked 
  differentiating 
  characters, 
  and 
  is 
  always 
  more 
  or 
  less 
  ornamented 
  

   with 
  whitish 
  opaque 
  flammulations 
  on 
  a 
  dark-brown 
  ground.
