  The 
  rejection 
  of 
  Clionella, 
  Gray, 
  1847, 
  in 
  favour 
  of 
  MeJatoma, 
  

   Swainson, 
  1840, 
  seems 
  to 
  need 
  reconsideration, 
  judging 
  from 
  

   Swainson's 
  ligure, 
  since 
  the 
  South 
  African 
  Clionella 
  has 
  a 
  short 
  

   canal 
  quite 
  unlike 
  the 
  long 
  canal 
  indicated 
  by 
  Swainson. 
  I 
  purpose 
  

   tracing 
  Swainson's 
  type, 
  and 
  in 
  the 
  meantime 
  counsel 
  the 
  retention 
  

   of 
  the 
  certain 
  name 
  Clionella. 
  

  

  Zafra 
  certainly 
  does 
  not 
  seem 
  referable 
  to 
  this 
  family, 
  but 
  I 
  suggest 
  

   we 
  are 
  confusing 
  several 
  "families" 
  through 
  the 
  influence 
  of 
  the 
  

   posterior 
  canal. 
  For 
  instance, 
  from 
  the 
  figure, 
  Scliepman's 
  

   Baphnellopsis 
  is 
  a 
  close 
  relation 
  to 
  the 
  groups 
  Dall 
  separated 
  as 
  

   Maculotriton, 
  etc., 
  the 
  canal 
  in 
  this 
  case 
  being 
  the 
  one 
  seen 
  in 
  the 
  

   Bursa 
  family, 
  and 
  not 
  of 
  Turrid 
  significance. 
  

  

  CoLiCHTPTUS, 
  gen. 
  nov. 
  for 
  Buccinum 
  fasiforme, 
  Broderip. 
  

  

  When 
  this 
  paper 
  was 
  read 
  I 
  had 
  written 
  Colicryptus 
  for 
  Bticcimim 
  

   fusiforme, 
  Broderip. 
  Since 
  then 
  I 
  received 
  Dall's 
  "Notes 
  on 
  

   Chrpsodomus 
  " 
  , 
  in 
  which 
  I 
  see 
  he 
  still 
  retains 
  Bjyptos, 
  Jeffreys, 
  and 
  

   says, 
  ^^ 
  Fusus 
  fenestratns, 
  Turton 
  {-\- 
  fusiforme, 
  Broderip, 
  + 
  Broderipii, 
  

   Jeffreys) 
  probably 
  belongs 
  to 
  this 
  genus." 
  Dall 
  thus 
  confirms 
  

   Dautzenberg 
  & 
  Fischer's 
  usage, 
  who 
  claim 
  priority 
  for 
  the 
  first 
  

   named, 
  indicating 
  also 
  the 
  latter 
  lias 
  been 
  anticipated 
  by 
  Kiener, 
  

   1834. 
  Their 
  statement 
  is, 
  however, 
  incorrect, 
  since 
  Broderip's 
  name 
  

   dates 
  from 
  1830, 
  not 
  1835, 
  as 
  given 
  by 
  those 
  authorities. 
  Fusus 
  

   fusiforme 
  has 
  not 
  much 
  likeness 
  to 
  the 
  other 
  members 
  of 
  the 
  group, 
  

   and 
  1 
  reject 
  Kryplos 
  as 
  preoccupied 
  by 
  Cryptus, 
  a 
  logical 
  conclusion 
  

   under 
  the 
  International 
  Bules 
  for 
  Nomenclature. 
  I 
  also 
  introduce 
  

   the 
  new 
  name 
  

  

  SiPHONOHBis 
  MARSHALLi 
  for 
  Fusus 
  atfetiuatus, 
  Jeffreys, 
  

   which 
  is 
  preoccupied 
  by 
  Fusus 
  alfenuaius, 
  Bhilippi 
  (Palseonto- 
  

   graphica, 
  Bd. 
  i, 
  pt. 
  ii, 
  March, 
  1847, 
  p. 
  72), 
  while 
  1 
  suggest 
  that 
  

   Marshall's 
  Fusus 
  cotisijnilis 
  is 
  founded 
  on 
  a 
  specimen 
  distorted 
  by 
  

   fracture. 
  

  

  I 
  am 
  quite 
  unable 
  to 
  understand 
  the 
  reason 
  of 
  Ball's 
  rejection 
  of 
  

   Nepfunea, 
  Bolten, 
  in 
  favour 
  of 
  Chrysodonius, 
  Swainson, 
  for 
  these 
  

   whelks, 
  seeing 
  that 
  the 
  former 
  is 
  absolutely 
  valid 
  and 
  has 
  been 
  

   current 
  for 
  many 
  years 
  without 
  question. 
  

  

  It 
  is 
  strange 
  to 
  find 
  so 
  doughty 
  a 
  champion 
  of 
  Boltenian 
  names 
  

   and 
  stalwart 
  a 
  protagonist 
  of 
  selection 
  of 
  type 
  by 
  elimination 
  calmly 
  

   throwing 
  over 
  both 
  with 
  the 
  callous 
  remark 
  (p. 
  214), 
  " 
  The 
  name 
  

   Neptnnea, 
  Bolten, 
  was 
  given 
  to 
  a 
  heterogeneous 
  collection 
  now 
  

   divided 
  into 
  eight 
  or 
  more 
  genera 
  of 
  several 
  distinct 
  families." 
  

  

  CoMINELLA 
  AND 
  EuTHEIA 
  DISCUSSED. 
  

  

  I 
  had 
  drawn 
  up 
  some 
  notes 
  on 
  the 
  species 
  classed 
  under 
  Cominella 
  

   and 
  Euthria, 
  when 
  the 
  Rev. 
  Dr. 
  A. 
  H. 
  Cooke 
  informed 
  me 
  he 
  

   was 
  engaged 
  upon 
  the 
  examination 
  of 
  the 
  radulse 
  of 
  these 
  groups. 
  

   I 
  therefore 
  withheld 
  my 
  notes 
  until 
  his 
  work 
  was 
  completed. 
  It 
  is 
  

   worthy 
  of 
  emphasis 
  that 
  his 
  results 
  coincide 
  more 
  or 
  less 
  with 
  my 
  

   own 
  conclusions 
  based 
  on 
  shell 
  characters, 
  proving 
  once 
  more 
  the 
  

   concordance 
  of 
  external 
  and 
  internal 
  features.
