  Specimens 
  of 
  an 
  Acmcea 
  from 
  Bombay 
  have 
  recently 
  been 
  presented 
  

   to 
  the 
  British 
  Museum 
  hj 
  Major 
  A. 
  J. 
  Peile, 
  R.A., 
  and 
  as 
  the 
  genus 
  

   lias 
  not 
  been 
  until 
  recently^ 
  recorded 
  as 
  inhabiting 
  the 
  shores 
  of 
  

   India, 
  it 
  seemed 
  desirable 
  to 
  give 
  an 
  account 
  of 
  the 
  present 
  species. 
  

   Its 
  existence 
  at 
  Bombay, 
  however, 
  has 
  been 
  known 
  to 
  me 
  since 
  the 
  

   year 
  1882, 
  when 
  the 
  late 
  Dr. 
  W. 
  T. 
  Blanford 
  gave 
  to 
  the 
  Museum 
  

   a 
  dozen 
  examples. 
  These, 
  however, 
  were 
  only 
  about 
  half 
  the 
  size 
  of 
  

   those 
  received 
  from 
  Major 
  Peile. 
  

  

  The 
  shores 
  of 
  Bombay 
  are 
  not 
  very 
  prolific 
  in 
  limpet-like 
  forms 
  

   such 
  as 
  Patella, 
  AcmcBa, 
  etc. 
  Messrs. 
  Melvill 
  & 
  Abercrombie- 
  enumerate 
  

   the 
  following: 
  — 
  

  

  1. 
  Fissurella 
  Bomhayana, 
  Sow. 
  = 
  lima, 
  Sow. 
  

  

  2. 
  Emarg 
  inula 
  elongata, 
  Phil. 
  

  

  3. 
  E. 
  radiata, 
  Gould. 
  

  

  4. 
  Senium 
  tmgiiis 
  (Linn.). 
  

  

  5. 
  Patella 
  aster. 
  Reeve. 
  

  

  6. 
  Clypidina 
  notata 
  (Linn.). 
  

  

  N'o. 
  2. 
  Emargimda 
  elongata. 
  Philippi 
  never 
  published 
  a 
  species 
  

   under 
  this 
  name, 
  but 
  he 
  quoted^ 
  the 
  Mediterranean 
  shell 
  described 
  by 
  

   (Josta 
  with 
  that 
  appellation. 
  This 
  is 
  quite 
  distinct 
  from 
  the 
  shell 
  

   figured 
  by 
  A. 
  Adams 
  & 
  Sowerby 
  as 
  '■'■ 
  E. 
  elongata, 
  Philippi".'* 
  

  

  The 
  specimens 
  from 
  Bombay 
  thus 
  identified 
  have 
  kindly 
  been 
  sent 
  to 
  

   me 
  for 
  examination 
  by 
  Mr. 
  J. 
  C. 
  Melvill, 
  who 
  borrowed 
  them 
  from 
  the 
  

   Manchester 
  Museum, 
  where 
  they 
  were 
  placed 
  by 
  Mr. 
  Abercrombie, 
  by 
  

   whom 
  they 
  were 
  collected. 
  A 
  careful 
  study 
  of 
  them 
  proves 
  that 
  they 
  

   are 
  neither 
  the 
  elongata 
  of 
  Costa 
  nor 
  of 
  the 
  Thesaurus, 
  but 
  are 
  certainly 
  

   identical 
  with 
  E. 
  dilecta, 
  A. 
  Ad., 
  originally 
  said 
  to 
  be 
  from 
  King 
  

   George's 
  Sound, 
  South 
  Australia. 
  In 
  the 
  Museum 
  there 
  are 
  several 
  

   specimens 
  collected 
  at 
  Bombay 
  by 
  Mrs. 
  Deakin, 
  by 
  whom 
  they 
  were 
  

   presented. 
  

  

  The 
  '■'■ 
  E. 
  elongata, 
  Philippi" 
  of 
  the 
  Abercrombie 
  & 
  Melvill 
  list 
  

   must 
  therefore 
  be 
  regarded 
  as 
  a 
  mere 
  nomen 
  nudum. 
  

  

  No. 
  3. 
  The 
  Emarginula 
  ( 
  Clypidinai) 
  radiata 
  was 
  described 
  by 
  Gould 
  

   from 
  Sydney 
  Harbour, 
  and 
  was 
  supposed 
  by 
  Tenison- 
  Woods 
  to 
  be 
  the 
  

   same 
  species 
  as 
  E. 
  amtralis, 
  Lamk. 
  As 
  Lamarck 
  never 
  described 
  an 
  

   E. 
  au&tralis, 
  possibly 
  the 
  species 
  characterized 
  under 
  that 
  name 
  by 
  

   Quoy 
  & 
  Gaimard 
  was 
  referred 
  to. 
  

  

  I 
  have 
  not 
  seen 
  any 
  specimens 
  from 
  Bombay, 
  so 
  cannot 
  confirm 
  the
