  An 
  elegant 
  tornate 
  species, 
  -with 
  produced 
  canal, 
  and 
  spiral 
  ribbing 
  

   somewhat 
  similar 
  to 
  that 
  of 
  PL 
  nivea, 
  Phil., 
  but 
  more 
  regular. 
  

   "White, 
  tinted 
  j-ellowish 
  around 
  the 
  upper 
  double 
  carinsB 
  of 
  each 
  

   whorl 
  ; 
  just 
  below 
  the 
  sutures 
  these 
  carinae 
  are 
  spirally 
  deeply 
  

   punctulate, 
  an 
  item 
  omitted 
  in 
  the 
  original 
  description. 
  These 
  

   additional 
  notes 
  are 
  taken 
  from 
  the 
  specimen 
  noted 
  as 
  from 
  the 
  cable, 
  

   west 
  of 
  Eorabay. 
  The 
  dimensions 
  of 
  this 
  are 
  long. 
  20, 
  hit. 
  6 
  mm. 
  As 
  

   regards 
  the 
  nuclear 
  whorls, 
  the 
  first 
  two 
  are 
  vitreous, 
  globular,, 
  

   smooth, 
  and 
  shining, 
  the 
  two 
  next, 
  also 
  vitreous, 
  but 
  spirally 
  

   nodulous.

  This 
  may, 
  perhaps, 
  stand 
  on 
  its 
  own 
  merits, 
  as 
  distinct 
  from 
  

   violacea^ 
  Hinds, 
  with 
  which 
  several 
  authors 
  have 
  placed 
  it. 
  It 
  differs 
  

   in 
  size, 
  also 
  in 
  less 
  prominent 
  spiral 
  ribbing, 
  the 
  characteristics 
  of 
  

   which, 
  however, 
  are 
  almost 
  identical, 
  and, 
  above 
  all, 
  the 
  chestnut 
  zigzag 
  

   longitudinal 
  markings 
  down 
  tlie 
  whorls, 
  the 
  same 
  colour 
  permeating 
  

   the 
  sutural 
  region 
  in 
  more 
  or 
  less 
  density. 
  My 
  largest 
  examjjle 
  only 
  

   measures 
  17 
  mm. 
  in 
  length, 
  while 
  nivea 
  attains 
  25 
  mm. 
  or 
  more. 
  

   I 
  have 
  lately 
  received 
  characteristic 
  Japanese 
  specimens, 
  collected 
  by 
  

   Hirase. 
  The 
  cliestnut 
  painting 
  is 
  distinct 
  and 
  peculiar, 
  in 
  zigzag 
  

   longitudinal 
  flames 
  on 
  white 
  ground.

  In 
  my 
  description 
  of 
  this 
  species 
  I 
  omitted 
  to 
  mention 
  that 
  

   A. 
  travancorica, 
  Smith, 
  a 
  very 
  fine 
  and 
  large 
  abysmal 
  species, 
  of 
  

   ornate 
  sculpture, 
  had 
  already 
  been 
  recorded 
  from 
  the 
  Eastern 
  tropical 
  

   area, 
  some 
  way 
  south 
  of 
  our

  following 
  

   Cossmann's

  considers 
  Aytcistrosyrinx,

  preoccupied 
  by 
  

   Cochlespira,

  Tryon, 
  however, 
  thinks
