  Karachi. 
  Angrias 
  Bank 
  and 
  Malabar 
  Coast 
  (Captain 
  Tindall), 
  

   5 
  fathoms. 
  

  

  This 
  is 
  a 
  plentiful 
  species, 
  and 
  appears 
  to 
  be 
  more 
  " 
  inconstant" 
  

   in 
  colour 
  than 
  form. 
  The 
  hue 
  varies 
  from 
  pale 
  straw 
  colour 
  and 
  

   almost 
  white 
  to 
  chocolate-brown. 
  Sometimes 
  the 
  tubercles, 
  spirally 
  

   arranged 
  below 
  the 
  sutures, 
  are 
  shining 
  white, 
  the 
  rest 
  of 
  the 
  shell 
  

   being 
  darker, 
  but 
  this 
  is 
  a 
  rare 
  variety. 
  So 
  nearly 
  akin 
  is 
  this 
  

   species 
  to 
  certain 
  forms 
  of 
  pyramidula, 
  lleeve, 
  that 
  I 
  expect 
  they 
  will 
  

   be 
  united 
  some 
  day, 
  if 
  not 
  immediately.

  fathoms,

  past 
  Charbar,

  to 
  

   Gwadur. 
  

  

  A 
  handsome 
  species, 
  at 
  one 
  time 
  rather 
  confounded 
  with 
  haijnhami, 
  

   Sm. 
  It 
  is 
  still 
  very 
  abundant 
  where 
  found, 
  and 
  we 
  have 
  seen 
  many 
  

   specimens 
  without 
  much 
  variety. 
  The 
  dark-brown 
  blotches 
  at 
  the 
  

   interstices 
  are 
  very 
  conspicuous: 
  the 
  trivial 
  name 
  was 
  imposed 
  in 
  

   recognition 
  of 
  tliis. 
  The 
  canal 
  is 
  somewhat 
  produced, 
  form 
  more 
  

   attenuate 
  proportionately 
  than 
  most 
  of 
  its 
  congeners. 
  It 
  is 
  mentioned 
  

   by 
  Hidalgo 
  as 
  occurring 
  at 
  the 
  Island 
  of 
  Cebu, 
  Philippines.

  A 
  small 
  nodulous 
  species, 
  of 
  the 
  same 
  character 
  as 
  vico?isfans, 
  Sm., 
  

   prumdum,

  but 
  with 
  the 
  spiral 
  nodules 
  much 
  

   fewer 
  and 
  larger 
  in 
  proportion. 
  It 
  is 
  of 
  very 
  rare 
  occurrence.

   10

  The 
  type 
  of 
  lucida 
  is 
  in 
  the 
  Indian 
  Museum, 
  Calcutta, 
  and 
  we, 
  

   therefore, 
  have 
  not 
  had 
  an 
  opportunity 
  for 
  comparing 
  it 
  with 
  disjecta, 
  

   but 
  judging 
  from 
  the 
  good 
  figure, 
  which 
  is 
  drawn 
  on 
  a 
  considerably 
  

   magnified 
  scale, 
  there 
  can 
  be 
  little 
  doubt 
  that 
  these 
  are 
  one 
  and 
  the 
  

   selfsame 
  species. 
  We 
  have 
  figured 
  the 
  actual 
  type 
  of 
  disjecta 
  from 
  

   the 
  National 
  Collection. 
  Mr. 
  Smith 
  lays 
  stress 
  upon 
  the 
  upper 
  ribs 
  

   in 
  this 
  species 
  being 
  always 
  nodulous, 
  and 
  thus 
  being 
  capable 
  of 
  

   being 
  distinguished 
  from 
  the 
  very 
  neai'ly 
  allied 
  persica 
  at 
  sight. 
  To 
  

   my 
  mind, 
  nevertheless, 
  these 
  species 
  are 
  almost 
  too 
  near, 
  and 
  mainly
