  at 
  47 
  fathoms 
  100 
  miles 
  west 
  of 
  Bombay. 
  

   Small 
  examples 
  near 
  the 
  month 
  of 
  the 
  Iliver 
  Indus, 
  Karachi. 
  

  

  This 
  species 
  has 
  likewise 
  been 
  received 
  from 
  Andaman 
  Isles 
  

   (Booley),' 
  whence 
  indeed 
  the 
  original 
  type 
  came. 
  It 
  is 
  also 
  

   reported 
  from 
  Erythraean 
  waters. 
  We 
  have 
  figured 
  the 
  type, 
  

   representing 
  a 
  much 
  broader 
  shell 
  than 
  is 
  the 
  case 
  with 
  its 
  congeners, 
  

   tayloriana, 
  live., 
  and 
  theoreta, 
  Mel 
  v. 
  The 
  examples 
  I 
  received 
  from 
  

   the 
  late 
  Mr. 
  G. 
  Booley, 
  just 
  mentioned, 
  are 
  pale 
  in 
  colour, 
  freckled 
  

   with 
  pale 
  brown, 
  and 
  echinately 
  noduled.

   Montfort, 
  1810). 
  

  

  Mr. 
  Iredale 
  assures 
  me 
  it 
  is 
  antagonistic 
  to 
  the 
  laws 
  of 
  priority 
  to 
  

   continue 
  using 
  the 
  name 
  " 
  Clavus 
  " 
  subgenerically, 
  it 
  having 
  been 
  

   published 
  by 
  Montfort 
  twenty-eight 
  years 
  earlier 
  for 
  a 
  different 
  

   group 
  than 
  the 
  accepted 
  generic 
  '■'■ 
  Brillia 
  ", 
  Gray, 
  1838. 
  Accordingly, 
  

   a 
  new 
  cognomen 
  being 
  necessary, 
  I 
  venture 
  to 
  propose 
  Tylotia, 
  which, 
  

   being 
  derived 
  from 
  ti1\os, 
  a 
  nail 
  or 
  club, 
  has 
  tlie 
  same 
  meaning 
  as 
  

   Clavus. 
  The 
  type 
  appears 
  to 
  be 
  cMiicularis,

  Originally 
  described 
  from 
  the 
  Philippines, 
  the 
  present 
  record 
  shows 
  

   considerable 
  extension 
  of 
  range 
  westward. 
  It 
  has 
  not 
  occurred 
  yet 
  

   further 
  north. 
  

  

  Mr. 
  C. 
  Hedley 
  ' 
  uses 
  Gmelin's 
  name 
  ; 
  but 
  Iredale^ 
  does 
  not 
  agree 
  

   with 
  this, 
  and 
  writes 
  exhaustive 
  reasons 
  in 
  favour 
  of 
  Bolten's 
  name 
  

   being 
  employed. 
  I 
  am 
  very 
  grateful 
  to 
  !Mr. 
  Iredale 
  for 
  the 
  advice 
  

   he. 
  has 
  given 
  me 
  on 
  this 
  subject. 
  This 
  species 
  I 
  consider 
  the 
  type 
  of 
  

   the 
  section.

  This 
  species 
  might, 
  perhaps, 
  be 
  occasionally 
  confused 
  with 
  sacra, 
  

   lleeve 
  ; 
  the 
  author, 
  in 
  comparing 
  the 
  two, 
  mentions 
  the 
  violet

  crassa,
