  conclusious, 
  based 
  on 
  published 
  accounts, 
  need 
  reconsideration, 
  as 
  

   for 
  instance 
  "two 
  (species) 
  at 
  least 
  of 
  which 
  are 
  also 
  found 
  in 
  

   Australian 
  waters". 
  This 
  refers 
  to 
  Neozelanic 
  species 
  and 
  the 
  two 
  

   cited 
  '■'■ 
  costata, 
  Qiioy, 
  Imeolata, 
  Lam." 
  are 
  not 
  truly 
  Neozelanic. 
  

   I 
  determined 
  a 
  dead 
  shell 
  as 
  referable 
  to 
  the 
  first 
  named, 
  but 
  I 
  am 
  

   sure 
  now 
  that 
  was 
  a 
  mistake. 
  Neither 
  does 
  the 
  genus 
  occur 
  at 
  the 
  

   Kermadecs 
  as 
  given 
  by 
  Suter. 
  It 
  is 
  remarkable 
  that 
  one 
  of 
  the 
  

   radulae 
  figured 
  by 
  Dr. 
  Cooke 
  (ex 
  Gwatkin 
  coll.) 
  should 
  have 
  been 
  

   named 
  as 
  '■'costata., 
  Quoy 
  : 
  New 
  Zealand", 
  and 
  I 
  cannot 
  recognize 
  to 
  

   what 
  it 
  really 
  belonged. 
  The 
  genus 
  name 
  Cominella 
  was 
  proposed 
  

   by 
  Gray 
  in 
  1850 
  (Fig. 
  Moll. 
  Anim., 
  vol. 
  Tv, 
  p. 
  72), 
  the 
  species 
  

   attached 
  being 
  testndinea, 
  maculosa, 
  etc., 
  and 
  the 
  first-named 
  figured. 
  

   I_]iere 
  designate 
  that,as 
  type. 
  As 
  shown 
  by 
  Dr. 
  Cooke, 
  tlie 
  radulae 
  of 
  

   the 
  Austro-Neozelunic 
  species 
  are 
  similar 
  in 
  type 
  and 
  consequently 
  

   shell 
  characters 
  have 
  to 
  be 
  considered. 
  The 
  costata-lurida 
  group 
  

   show 
  a 
  constant 
  shell 
  formation 
  very 
  different 
  from 
  adspersa, 
  maculosa, 
  

   and 
  virgata. 
  These 
  last 
  three 
  diff'er 
  among 
  themselves, 
  and 
  a 
  more 
  

   detailed 
  examination 
  will 
  probably 
  result 
  in 
  their 
  separation. 
  At 
  

   the 
  present 
  time 
  I 
  propose 
  to 
  deal 
  with 
  tlie 
  South 
  African" 
  Cow«m^//«", 
  

   which 
  are 
  readily 
  separable 
  by 
  shell 
  characters 
  and 
  whose 
  radulse 
  are 
  

   remarkably 
  difl'erent. 
  The 
  exact 
  names 
  of 
  these 
  species 
  will 
  be 
  

   dealt 
  with 
  later, 
  but 
  I 
  introduce 
  Afrocominella 
  for 
  elongata, 
  Dunker, 
  

   and 
  tigrina, 
  Kiener, 
  designating 
  the 
  former 
  as 
  type, 
  and 
  propose 
  

   Burnupena 
  for 
  the 
  peculiarly 
  distinct 
  group, 
  delalandii, 
  Kiener, 
  

   lagenaria, 
  Lam., 
  limbosa, 
  Lam., 
  and 
  p)oycata, 
  Gmelin, 
  designating 
  the 
  

   last 
  named 
  as 
  type, 
  while 
  pointing 
  out 
  that 
  the 
  species 
  name 
  is 
  

   preoccupied 
  and 
  that 
  it 
  should 
  be 
  cincta, 
  Bolten 
  (Mus. 
  Bolten, 
  1798, 
  

   p. 
  113), 
  proposed 
  for 
  Martini, 
  4, 
  t. 
  126, 
  figs. 
  1213-14. 
  So 
  that 
  the 
  

   type 
  name 
  stands 
  JBurnupena 
  cincta 
  (Bolten). 
  

  

  With 
  regard 
  to 
  the 
  radula 
  of 
  Euthria, 
  Dr. 
  Cooke 
  has 
  shown 
  that 
  

   diverse 
  groups 
  have 
  been 
  confounded 
  under 
  this 
  name, 
  a 
  fact 
  

   communicated 
  to 
  me 
  by 
  Professor 
  Gwatkin 
  many 
  years 
  ago. 
  Cooke 
  

   places 
  the 
  Neozelanic 
  li7iea, 
  Martyn, 
  with 
  the 
  European 
  cornea, 
  L., 
  

   the 
  type 
  of 
  the 
  genus 
  : 
  the 
  radula 
  is 
  somewhat 
  different 
  and 
  the 
  shell 
  

   decidedly 
  so, 
  that 
  I 
  revive 
  for 
  it 
  the 
  genus 
  name 
  Evarne, 
  proposed 
  by 
  

   H. 
  & 
  A. 
  Adams, 
  but 
  afterwards 
  ignored. 
  The 
  otlier 
  Neozelanic 
  

   species 
  cannot 
  be 
  classed 
  with 
  linea, 
  so 
  I 
  introduce 
  the 
  name 
  Euthrena 
  

   for 
  them, 
  naming 
  vittata, 
  Quoy 
  & 
  Gaimurd, 
  as 
  type. 
  

  

  The 
  extraordinary 
  radula 
  presented 
  by 
  ferrea, 
  Reeve, 
  from 
  Japan, 
  

   proves 
  at 
  once 
  that 
  this 
  species 
  is 
  no 
  relatloii 
  to 
  either 
  the 
  European 
  

   Euthria 
  or 
  the 
  Southern 
  so-called 
  Euthria. 
  In 
  order 
  to 
  attract 
  

   attention 
  I 
  propose 
  Ja])euthria 
  for 
  Reeve's 
  species 
  alone. 
  Cooke 
  

   shows 
  by 
  means 
  of 
  the 
  radulfe 
  that 
  the 
  Magellanic 
  species 
  of 
  Euthria 
  

   belong 
  in 
  reality 
  to 
  Cominella, 
  a 
  fact 
  I 
  pointed 
  out 
  to 
  Messrs. 
  

   E. 
  A. 
  Smith 
  and 
  H. 
  B. 
  Preston 
  some 
  years 
  ago 
  from 
  consideration 
  of 
  

   conchological 
  features 
  alone. 
  

  

  Syntagma, 
  nom. 
  nov. 
  for 
  Bonovania,

  &

  In 
  an 
  essay 
  on 
  Crustacea 
  in 
  Brewster's 
  Edinburgh 
  Encyclopedia, 
  

   vol. 
  vii, 
  1814, 
  Leach 
  proposed 
  the 
  generic 
  names 
  Bonovania 
  (p. 
  435),
