﻿76 
  COLLECTIONS 
  FROM 
  MELANESIA. 
  

  

  Messrs. 
  Adams 
  described 
  these 
  spots 
  as 
  being 
  " 
  round 
  '' 
  in 
  the 
  

   specimen 
  they 
  examined 
  ; 
  in 
  those 
  before 
  me 
  they 
  are 
  rather 
  

   angular, 
  being 
  the 
  zigzag 
  turn 
  of 
  the 
  longitudinal 
  lines. 
  A 
  third 
  

   variety 
  has 
  a 
  pale 
  band 
  round 
  the 
  middle 
  of 
  the 
  last 
  volution 
  which 
  

   falls 
  at 
  the 
  lower 
  part 
  of 
  the 
  upper 
  ones, 
  the 
  upper 
  portion 
  being 
  

   pinkish 
  or 
  closely 
  lincolatcd 
  with 
  pink. 
  The 
  lower 
  half 
  of 
  the 
  body- 
  

   whorl 
  has 
  a 
  broad 
  pinkish 
  band 
  beneath 
  the 
  cent 
  ralwhite 
  one, 
  which 
  

   is 
  succeeded 
  by 
  a 
  narrower 
  plain 
  zone, 
  which 
  in 
  turn 
  is 
  followed 
  by 
  

   another 
  fine 
  pink 
  one. 
  

  

  A 
  fourth 
  form, 
  with 
  the 
  exception 
  of 
  the 
  upper 
  part 
  of 
  the 
  spire 
  

   and 
  the 
  umbilical 
  region, 
  is 
  of 
  a 
  uniform 
  greyish 
  violet. 
  

  

  The 
  largest 
  specimen 
  is 
  twelve 
  millim. 
  long, 
  and 
  consists 
  of 
  

   eight 
  whorls. 
  The 
  spiral 
  sulcation 
  and 
  ridging 
  is 
  much 
  more 
  deve- 
  

   loped 
  in 
  some 
  specimens 
  than 
  others. 
  In 
  the 
  largest 
  there 
  is 
  quite 
  

   a 
  strong 
  keel 
  near 
  the 
  base 
  of 
  the 
  upper 
  whorls, 
  which 
  gradually 
  

   diminishes 
  upon 
  the 
  last. 
  In 
  others 
  the 
  whorls 
  are 
  almost 
  smooth, 
  

   with 
  the 
  exception 
  of 
  the 
  base 
  of 
  the 
  last, 
  which 
  invariably 
  presents 
  

   a 
  few 
  sulci 
  circumscribing 
  the 
  narrow 
  umbilicus. 
  The 
  presence 
  of 
  

   the 
  latter 
  peculiarity 
  and 
  the 
  very 
  slight 
  difference 
  in 
  the 
  columella 
  

   do 
  not 
  appear 
  to 
  me 
  sufficient 
  characters 
  to 
  separate 
  this 
  species 
  

   generically 
  from 
  Banlcivia. 
  The 
  general 
  form 
  of 
  the 
  shell, 
  its 
  

   texture, 
  and 
  the 
  style 
  and 
  variation 
  of 
  painting 
  are 
  the 
  same. 
  Other 
  

   points 
  of 
  resemblance 
  are 
  the 
  thickening 
  or 
  margination 
  of 
  the 
  whorls 
  

   at 
  the 
  suture, 
  the 
  striation 
  or 
  sulcation 
  of 
  the 
  base 
  of 
  the 
  last, 
  the 
  

   non-pearly 
  aperture, 
  and 
  finally 
  their 
  geogi'aphical 
  distribution. 
  

  

  A 
  second 
  species 
  (?) 
  of 
  the 
  section 
  Le'wpiinia 
  has 
  been 
  briefly 
  

   described 
  by 
  A. 
  Adams 
  (P. 
  Z. 
  S. 
  1863, 
  p. 
  507) 
  from 
  Port 
  Essington, 
  

   under 
  the 
  name 
  of 
  L. 
  cingulata. 
  It 
  presents 
  similar 
  variations 
  in 
  

   colouring 
  as 
  in 
  the 
  other 
  species, 
  and, 
  indeed, 
  might 
  even 
  be 
  con- 
  

   sidered 
  another 
  form 
  of 
  it 
  with 
  the 
  carinations 
  and 
  lirae 
  more 
  pro- 
  

   nounced.
