  now 
  engaged 
  upon 
  t)ie 
  Australian 
  forms, 
  and 
  later 
  I 
  hope 
  to 
  develop 
  

   some 
  points 
  that 
  have 
  cropped 
  up 
  in 
  this 
  connexion.

   note

  a

  Otitoma

  The 
  

   " 
  cyclophora 
  " 
  group 
  needed 
  a 
  name, 
  but 
  clandestina 
  might 
  have 
  

   been 
  called 
  years 
  ago 
  by 
  Melvill 
  " 
  a 
  typical 
  Clathurella". 
  

  

  Gabkielona, 
  gen.

  I 
  introduce 
  this 
  name 
  for 
  Phasianella 
  nepeanensis. 
  Gatliff 
  & 
  Gahriel 
  

   (I'roc. 
  lloy. 
  Soc. 
  Victoria, 
  n.s., 
  vol. 
  xxi, 
  August, 
  1908, 
  p. 
  306, 
  pi. 
  xxi, 
  

   figs. 
  9-10), 
  Flinders, 
  Western 
  Pcjrt, 
  Victoria. 
  The 
  describers 
  were 
  

   dubious 
  as 
  to 
  the 
  generic 
  location, 
  and 
  I 
  some 
  time 
  ago 
  sorted 
  out 
  

   a 
  shell 
  undoubtedly 
  congeneric, 
  from 
  Lord 
  Howe 
  Island. 
  I 
  was 
  

   fortunate 
  enough 
  to 
  recover 
  live 
  sj)ecimens 
  showing 
  the 
  opercular 
  

   characters. 
  Peculiarly 
  enough 
  the 
  operculum 
  is 
  shelly, 
  though 
  of 
  

   quite 
  a 
  dilferent 
  nature 
  to 
  that 
  of 
  Phasianella, 
  while 
  tlie 
  animal 
  has 
  

   been 
  large 
  and 
  leaves 
  a 
  dead 
  fringe 
  round 
  the 
  mouth. 
  I 
  will 
  return 
  

   to 
  this 
  point 
  at 
  a 
  later 
  opportunity, 
  but 
  here 
  propose 
  the 
  above 
  

   name 
  since 
  the 
  further 
  account 
  may 
  be 
  much 
  delayed. 
  I 
  have 
  just 
  

   received, 
  through 
  the 
  generosity 
  of 
  Dr. 
  W. 
  G. 
  Torr, 
  a 
  parcel 
  of 
  

   shell-sand 
  from 
  Port 
  Lincoln, 
  South 
  Australia, 
  from 
  which 
  I 
  have 
  

   sepai'uted 
  a 
  specimen, 
  apparently 
  nepeanensis, 
  G. 
  & 
  G. 
  While 
  the 
  

   genus 
  may 
  be 
  classed 
  for 
  the 
  present 
  in 
  the 
  family 
  Phasianellidaj, 
  

   I 
  do 
  not 
  think 
  it 
  has 
  really 
  any 
  close 
  relationship 
  with 
  Phasianella. 
  

   The 
  Lord 
  Howe 
  shells 
  are 
  sub-littoral 
  in 
  habit, 
  so 
  that 
  the 
  Australian 
  

   shell 
  may 
  be 
  sought 
  for 
  in 
  shallow-water 
  dredgings. 
  The 
  occurrence 
  

   of 
  the 
  dead 
  shell 
  in 
  shell-sand 
  from 
  South 
  Australia 
  indicates 
  a 
  sub- 
  

   littoral 
  habit 
  there. 
  The 
  recovery 
  of 
  live 
  specimens 
  and 
  examination 
  

   of 
  the 
  radula 
  will 
  assist 
  in 
  classifying 
  it, 
  and 
  a 
  Naticoid 
  affinity 
  

   suggests 
  itself 
  to 
  me 
  judging 
  from 
  the 
  shell 
  characters 
  and 
  the 
  

   operculum 
  and 
  dead 
  animal 
  of 
  the 
  Lord 
  Howe 
  species. 
  

  

  The 
  genus 
  is 
  named 
  in 
  honour 
  of 
  Mr. 
  C. 
  J. 
  Gabriel, 
  whose 
  energy 
  

   in 
  connexion 
  with 
  the 
  Victorian 
  Mollusca 
  is 
  well 
  known 
  and 
  

   appreciated, 
  and 
  whose 
  assistance 
  to 
  myself 
  in 
  many 
  ways 
  I 
  wish 
  to 
  

   commemorate. 
  

  

  Oebitestella, 
  gen. 
  nov. 
  

  

  I 
  propose 
  this 
  name 
  and 
  designate 
  as 
  type 
  Ci/clostrema 
  hastowi, 
  

   Gatlitf 
  (Proc. 
  Hoy. 
  Soc. 
  Vict., 
  N.s., 
  vol. 
  xix, 
  1906, 
  p. 
  3, 
  jd. 
  ii, 
  figs. 
  8-10, 
  

   Victoria). 
  I 
  also 
  indicate 
  it 
  as 
  representative 
  of 
  a 
  new 
  family 
  

   Orbitestellidse, 
  which 
  is 
  composed 
  of 
  a 
  series 
  of 
  minute 
  marine 
  

   molluscs 
  with 
  the 
  following 
  characters 
  : 
  Shell 
  thin, 
  pellucid, 
  dis- 
  

   coidal, 
  dextral, 
  of 
  few 
  whorls 
  and 
  of 
  peculiar 
  sculpture 
  : 
  widely 
  

   umbilicate, 
  columella 
  vertical, 
  aperture 
  never 
  variced, 
  irregular 
  in 
  

   shape, 
  edges 
  thin. 
  

  

  I 
  had 
  hoped 
  to 
  describe 
  the 
  group, 
  giving 
  figures, 
  but 
  at 
  present 
  

   this 
  is 
  impossible. 
  I 
  have 
  species 
  from 
  various 
  parts 
  of 
  New
