  I 
  might 
  here 
  note 
  that 
  Mangelia 
  was 
  invented 
  by 
  Leach 
  and 
  

   accepted 
  by 
  llisso, 
  and 
  it 
  is 
  a 
  pure 
  coincidence 
  that 
  it 
  sliould 
  look 
  

   like 
  a 
  name 
  intended 
  to 
  honour 
  Mangili, 
  with 
  whom, 
  as 
  far 
  as 
  I 
  have 
  

   been 
  able 
  to 
  trace, 
  it 
  lias 
  absolutely 
  no 
  connexion. 
  Through 
  

   inattention 
  to 
  this 
  detail 
  some 
  of 
  our 
  most 
  conscientious 
  writers 
  have 
  

   spelt 
  it 
  Mangilia. 
  

  

  MuiucoDRUPA,

  A 
  certain 
  peculiar 
  shell 
  has 
  long 
  been 
  known 
  as 
  Ricinula 
  (or 
  

   Sistrum) 
  cancellata, 
  Quoy 
  & 
  Gaiuuird. 
  The 
  generic 
  name 
  was 
  

   inapplicable, 
  and 
  I 
  now 
  find 
  the 
  specific 
  one 
  also 
  doubly 
  invalid, 
  

   being 
  anticipated 
  as 
  well 
  as 
  preoccupied. 
  Firstly, 
  Drupa, 
  Bolten, 
  is 
  

   earlier 
  than 
  Ricinula 
  or 
  Sistrum, 
  as 
  well 
  as 
  Ricinella, 
  all 
  based 
  ou 
  

   the 
  pame 
  group. 
  The 
  shell 
  under 
  consideration 
  was 
  obviously 
  

   not 
  congeneric 
  with 
  the 
  members 
  of 
  that 
  genus. 
  Lumped 
  in, 
  

   however, 
  was 
  a 
  series 
  of 
  smaller 
  shells 
  whose 
  generic 
  name 
  appears 
  

   to 
  be 
  Morula, 
  and 
  it 
  was 
  likewise 
  discordant 
  with 
  these. 
  Shells 
  more 
  

   like, 
  also 
  included, 
  liave 
  been 
  separated 
  by 
  Martens 
  as 
  Semiricimila. 
  

   I 
  noted 
  this 
  name 
  used 
  subgenerically 
  in 
  the 
  Wissensch. 
  Ergeb. 
  

   Deutsch. 
  Tiefsee 
  Exped., 
  Valdivia, 
  1903, 
  vol. 
  vii, 
  pp. 
  95 
  and 
  137, 
  

   witliout 
  indication 
  of 
  novelty, 
  so 
  that 
  it 
  may 
  liave 
  been 
  previously 
  

   proposed, 
  but 
  the 
  name 
  does 
  not 
  appear 
  in 
  the 
  Zoological 
  liecord 
  so 
  

   far 
  as 
  I 
  have 
  seen. 
  I 
  therefore 
  name 
  muricina, 
  Blainville, 
  as 
  

   type, 
  and 
  for 
  the 
  shell 
  named 
  Purpura 
  fenestrata, 
  Blainville, 
  1832 
  

   = 
  cancellata, 
  Quoy 
  & 
  Gaimard, 
  1833, 
  not 
  of 
  Bolten, 
  1798, 
  I 
  add 
  

   Muricodrupa. 
  

  

  In 
  arriving 
  at 
  this 
  result 
  the 
  following 
  facts 
  came 
  to 
  light. 
  In 
  

   January, 
  1832, 
  Duclos 
  published 
  a 
  preliminaiy 
  note 
  (Ann. 
  Sci. 
  Nat., 
  

   torn. 
  XXV, 
  pp. 
  90-5) 
  on 
  Purpuroid 
  shells, 
  following 
  it 
  up 
  with 
  a 
  

   further 
  item 
  in 
  May 
  {op. 
  cit., 
  tom. 
  xxvi, 
  pp. 
  103-12), 
  describing 
  some 
  

   new 
  species, 
  and 
  declaring 
  his 
  intention 
  of 
  monogi'aphing 
  tlie 
  

   group 
  with 
  illustrations. 
  He 
  quoted 
  (p. 
  109) 
  the 
  publication 
  of 
  

   Valenciennes' 
  species, 
  P. 
  speciosa, 
  which 
  he 
  described 
  as 
  P. 
  centri- 
  

   quadra. 
  After 
  June, 
  but 
  before 
  August, 
  Blainville 
  ]>uhlished 
  a 
  

   complete 
  monograph, 
  and 
  therein 
  named 
  species 
  figured 
  by 
  Quoy 
  & 
  

   Gaimard 
  in 
  the 
  Atlas 
  to 
  the 
  Voyage 
  of 
  t\\Q 
  Antrolabe 
  under 
  vernacular 
  

   names, 
  the 
  text 
  to 
  thelatter 
  not 
  appearing 
  until 
  1833. 
  The 
  chronology 
  

   reads 
  thus: 
  Ante 
  May, 
  1832, 
  Valenciennes; 
  May, 
  1832, 
  Duclos; 
  

   joos^ 
  June,

  Blainville;
