  From 
  the 
  dredging 
  in 
  the 
  Gulf 
  of 
  Oman 
  come 
  the 
  narrow 
  forms 
  

   named 
  brevicula, 
  which, 
  I 
  have 
  no 
  doubt, 
  are 
  identical 
  with 
  those 
  

   called 
  diadema 
  from

  The 
  type 
  is 
  now 
  refigured, 
  as 
  the 
  first 
  did 
  not 
  give 
  details 
  

   correctly. 
  I 
  cannot 
  now 
  find 
  any 
  Bushire 
  specimens, 
  and 
  think 
  most 
  

   likely 
  they 
  belonged 
  to 
  M. 
  gemma, 
  A. 
  Ad. 
  If 
  this 
  be 
  so, 
  the 
  type 
  

   is 
  unique, 
  for 
  the 
  other 
  example 
  that 
  was 
  found 
  in 
  Bombay 
  shell-sand 
  

   at 
  the 
  same 
  time, 
  was 
  soon 
  mislaid, 
  and 
  never 
  reappeared.

  The 
  type 
  of 
  this 
  species, 
  now 
  in 
  the 
  Britisli 
  Museum, 
  is 
  well 
  

   figured, 
  and 
  exhibits 
  the 
  penultimate 
  whorl 
  with 
  two, 
  the 
  body-whorl 
  

   with 
  three 
  spiral 
  beaded 
  rows, 
  followed 
  by 
  a 
  strong 
  keel. 
  With 
  it 
  

   occurred 
  what 
  at 
  the 
  time 
  I 
  considered 
  the 
  same 
  species, 
  with 
  only 
  

   two 
  beaded 
  rows 
  on 
  the 
  last 
  whorl, 
  and 
  these 
  agree, 
  as 
  Mr. 
  Hedley 
  

   has 
  pointed 
  out,^
