  Figs. 
  9-14. 
  

  

  The 
  shells 
  here 
  noted 
  were 
  collected 
  by 
  Mr. 
  Pratt 
  on 
  the 
  Island 
  of 
  

   Wiak 
  and 
  a 
  smaller 
  unnamed 
  island 
  to 
  the 
  south-east 
  of 
  it. 
  

  

  1. 
  Xesta 
  attlica, 
  Pfr. 
  Wiak 
  I. 
  

  

  A 
  number 
  of 
  examples 
  of 
  this 
  species 
  were 
  obtained, 
  most 
  of 
  them 
  

   being 
  the 
  usual 
  colour 
  varieties, 
  but 
  two 
  are 
  new 
  to 
  me; 
  one 
  has 
  the 
  

   apical 
  whorls 
  white, 
  whilst 
  the 
  lower 
  whorls 
  are 
  covered 
  with 
  a 
  very 
  

   light 
  uniform 
  greenish-yellow 
  periostracura 
  ; 
  the 
  other 
  shows 
  various 
  

   shades 
  of 
  brown 
  from 
  reddish 
  to 
  a 
  dark 
  smoky 
  brown 
  ; 
  both 
  varieties 
  

   have 
  the 
  usual 
  darker-coloured 
  spiral 
  band 
  and 
  are 
  not 
  polished, 
  

   but 
  exhibit 
  a 
  duller 
  surface 
  than 
  is 
  usual 
  in 
  this 
  protean 
  species. 
  

  

  2. 
  Xesta 
  fraudulenta, 
  Smith. 
  Wiak 
  I. 
  

  

  In 
  addition 
  to 
  the 
  typical 
  form 
  one 
  or 
  two 
  specimens 
  were 
  collected 
  

   that 
  have 
  a 
  narrow 
  spiral 
  band 
  of 
  darker 
  colour 
  situate 
  just 
  above 
  the 
  

   periphery 
  of 
  the 
  last 
  whorl 
  and 
  continued 
  upwards 
  towards 
  the 
  spire. 
  

  

  3. 
  Xesta 
  poucKr-r,4NiCA, 
  Sarasin. 
  S.E. 
  of 
  Wiak 
  I. 
  

  

  Some 
  specimens 
  are 
  of 
  a 
  uniform 
  whitish 
  coloration 
  ; 
  others 
  have 
  

   a 
  narrow 
  reddisli-browu 
  band 
  at 
  the 
  suture, 
  which 
  is 
  continued 
  to 
  

   about 
  the 
  first 
  half 
  of 
  the 
  last 
  whorl. 
  

  

  4. 
  Chloiutis 
  circumuata, 
  Fer. 
  Wiak 
  I. 
  

   5. 
  CuLORrris 
  (Albersia) 
  zondlata, 
  Fer. 
  Wiak 
  I. 
  

   6. 
  Papcina 
  hero, 
  Smith. 
  S.E. 
  of 
  Wiak 
  I. 
  

  

  Very 
  large 
  examples 
  of 
  this 
  handsome 
  species; 
  the 
  type 
  is 
  smaller, 
  

   but 
  not 
  so 
  small 
  as 
  some 
  specimens 
  that 
  were 
  collected 
  on 
  a 
  former 
  

   expedition 
  by 
  Mr. 
  Pratt 
  at 
  Muswar 
  L, 
  Geelvink 
  Bay; 
  the 
  species 
  

   evidently 
  varies 
  greatly 
  in 
  size. 
  

  

  7. 
  Papuina 
  trochiformis, 
  Preston. 
  Wiak 
  I. 
  

  

  Two 
  specimens, 
  both 
  of 
  which 
  have 
  a 
  somewhat 
  higher 
  spire 
  than 
  

   the 
  ty[)e, 
  bat 
  agree 
  well 
  with 
  it 
  in 
  other 
  respects. 
  

  

  8. 
  Papuina 
  subcostata, 
  n.sp. 
  PI. 
  Ill, 
  Figs. 
  12-14. 
  

  

  Shell 
  depressed 
  trochoid, 
  moderately 
  solid, 
  openly 
  umbilicated 
  to 
  

   a 
  width 
  of 
  about 
  4 
  mm., 
  light 
  brown 
  with 
  a 
  rather 
  broad 
  band 
  of 
  

   darker 
  brown 
  encircling 
  the 
  last 
  whorl, 
  situated 
  just 
  above 
  the 
  middle 
  

   and 
  continued 
  upwards 
  for 
  a 
  short 
  distance 
  at 
  the 
  suture 
  of 
  the
