  the

  Tl)e 
  good 
  fio:ures 
  showed 
  it 
  to 
  be 
  the 
  

   nucleus 
  of 
  a 
  Vermetid, 
  and 
  Mr. 
  J. 
  R.

  has 
  recovered 
  

   examples

  The 
  above 
  name 
  is 
  proposed 
  because 
  the 
  species 
  selected 
  as 
  type 
  is 
  

   not 
  congeneric 
  with 
  those 
  recently 
  associated 
  under 
  Bela, 
  and 
  the 
  

   correct 
  generic 
  name 
  of 
  which 
  is 
  Oenopota, 
  Morch. 
  Most 
  recent 
  

   authorities 
  have 
  agreed 
  with 
  this 
  conclusion, 
  but 
  liave 
  not 
  rectified 
  

   tlie 
  error.

  A. 
  Adams 
  (Ann. 
  & 
  Mag. 
  Nat. 
  Hist., 
  ser. 
  in, 
  vol. 
  xi, 
  April, 
  1863, 
  

   p. 
  267) 
  introduced 
  a 
  genus 
  Calceolina, 
  writing, 
  " 
  This 
  little 
  genus 
  

   is 
  established 
  on 
  a 
  shell 
  I 
  found 
  at 
  Tanabe, 
  and 
  whicli 
  I 
  believe 
  to 
  

   be 
  the 
  same 
  as 
  the 
  JVeriti^ia 
  pusilla 
  of 
  C. 
  h. 
  Adams." 
  The 
  genus 
  and 
  

   species 
  were 
  then 
  described, 
  and 
  since 
  the 
  generic 
  name 
  had 
  been 
  

   anticipated 
  by 
  llafinesque 
  almost 
  fifty 
  years 
  before, 
  and 
  the 
  species 
  

   is 
  not 
  that 
  of 
  C. 
  B. 
  Adams, 
  I 
  introduce 
  the 
  new 
  generic 
  name 
  

   Calceolata, 
  while 
  the 
  new 
  specific 
  name 
  will 
  be 
  anomala. 
  

   MiCROTHYCA 
  stands 
  instead 
  of 
  Microtheca. 
  

  

  Two 
  pages 
  earlier 
  A. 
  Adams 
  (op. 
  cit.) 
  ^pro-posed 
  Mtcrothi/ca, 
  and 
  this 
  

   was 
  altered 
  to 
  Microtheca, 
  and 
  has 
  since 
  commonly 
  been 
  so 
  spelt; 
  in 
  

   the 
  latter 
  state 
  it 
  is 
  invalid, 
  so 
  that 
  reversion 
  must 
  be 
  made 
  to 
  the 
  

   first 
  spelling, 
  otherwise 
  a 
  new 
  name 
  would 
  be 
  necessary.

  Dr. 
  Dall 
  has 
  recently 
  published 
  (April 
  5, 
  1918) 
  two 
  extremely 
  

   valuable 
  papers 
  in 
  the 
  Proc. 
  U.S. 
  Nut. 
  Mus., 
  vol. 
  liv, 
  entitled. 
  

   " 
  Notes 
  on 
  Chrysodonms 
  and 
  other 
  Mollusks 
  from 
  the 
  North 
  Pacific 
  

   Ocean" 
  (pp. 
  207-3-J), 
  and 
  "Notes 
  on 
  the 
  nomenclature 
  of 
  the 
  

   Mollusks 
  of 
  the 
  family 
  Tiirritidfe 
  " 
  (pp. 
  313-33). 
  Both 
  are 
  really 
  

   beyond 
  criticism, 
  and 
  the 
  points 
  I 
  here 
  deal 
  with 
  are 
  comparatively 
  

   trivial, 
  but 
  are 
  offered 
  to 
  complete 
  the 
  cases 
  and 
  draw 
  attention 
  to 
  

   such 
  items. 
  

  

  The 
  latter 
  is 
  a 
  most 
  complete 
  list 
  of 
  sectional 
  names, 
  and 
  though 
  

   I 
  have 
  been 
  noting 
  these 
  for 
  some 
  years, 
  I 
  can 
  scarcely 
  make 
  any 
  

   additions 
  save 
  with 
  regard 
  to 
  incomplete 
  references. 
  Dr. 
  Dall's 
  

   complete 
  work 
  will 
  be 
  a 
  most 
  invaluable 
  aid 
  to 
  the 
  student 
  of 
  these 
  

   most 
  puzzling 
  forms, 
  and 
  I 
  anticipate 
  many 
  more 
  sections 
  in 
  

   connexion 
  with 
  the 
  small 
  Indo-Pacific 
  species, 
  the 
  nuclear 
  characters 
  

   showing 
  diverse 
  origin 
  in 
  couchologically 
  simihir 
  shells, 
  the 
  differences 
  

   observed 
  beiu"; 
  radical, 
  such 
  as 
  the 
  contrast 
  being 
  a 
  highly 
  sculptured 
  

   "Sinusigera" 
  and 
  a 
  bulbous 
  one-whorled 
  smooth 
  turn. 
  

  

  Thus, 
  Tomopleura, 
  Casey, 
  is 
  a 
  well-marked 
  and 
  distinct 
  group 
  

   which 
  Dall, 
  in 
  one 
  place, 
  refers 
  to 
  Tmris, 
  s.str., 
  and 
  then 
  to 
  Teres, 
  

   with 
  neither 
  of 
  which 
  can 
  it 
  be 
  confused, 
  while 
  these 
  are 
  very 
  different 
  

   from 
  each 
  other.
