  The 
  present 
  communication 
  must 
  be 
  considered 
  a 
  continuation 
  of 
  

   my 
  papers 
  on 
  South-west 
  Victorian 
  Chilostomatous 
  Bryozoa 
  (Quart. 
  

   Journ. 
  Geol. 
  Soc. 
  vol. 
  xxxvii. 
  p. 
  309) 
  and 
  " 
  On 
  Chilostomatous 
  

   Bryozoa 
  from 
  Mount 
  Gambier 
  " 
  (Quart. 
  Journ. 
  Geol. 
  Soc. 
  xxxviii. 
  

   p. 
  257). 
  The 
  collection 
  was 
  lent 
  me 
  by 
  Mr. 
  J. 
  R. 
  Y. 
  Goldstein, 
  who, 
  

   I 
  presume, 
  collected 
  them 
  himself 
  from 
  Bairnsdale 
  ; 
  and 
  it 
  contains 
  

   several 
  very 
  interesting 
  specimens, 
  though, 
  in 
  consequence 
  of 
  the 
  

   other 
  two 
  collections 
  of 
  the 
  same 
  age 
  being 
  first 
  described, 
  the 
  

   number 
  of 
  species 
  not 
  previously 
  known 
  fossil 
  from 
  Australia 
  is 
  

   only 
  14 
  out 
  of 
  a 
  total 
  of 
  42. 
  

  

  There 
  are 
  several 
  species 
  now 
  found 
  in 
  the 
  Escliara-lorvn 
  which 
  

   are 
  known 
  in 
  other 
  places 
  incr 
  listing 
  ; 
  and 
  I 
  must 
  point 
  out 
  that 
  

   the 
  number 
  of 
  incrusting 
  species 
  in 
  this 
  collection 
  is 
  very 
  small, 
  

   though 
  possibly 
  this 
  may 
  depend 
  to 
  a 
  certain 
  extent 
  on 
  the 
  circum- 
  

   stances 
  under 
  which 
  they 
  were 
  collected. 
  Those 
  who 
  have 
  followed 
  

   these 
  three 
  papers 
  on 
  the 
  Australian 
  Bryozoa 
  will 
  have 
  noticed 
  in 
  

   how 
  many 
  cases 
  the 
  same 
  species 
  is 
  now 
  known 
  in 
  different 
  modes 
  

   of 
  growth 
  : 
  sometimes, 
  as 
  in 
  Membranipora 
  macrostoma, 
  Oribrilina 
  

   terminate,, 
  Mncronella 
  mucronata, 
  Porina 
  coronata, 
  Porina 
  larvalis, 
  

   Lepralia 
  foliacea, 
  Microporella 
  elevata, 
  and 
  Smittia 
  reticulata, 
  the 
  

   same 
  species 
  is 
  found 
  in 
  these 
  fossil 
  beds 
  in 
  more 
  than 
  one 
  form 
  ; 
  in 
  

   other 
  cases 
  we 
  find 
  species 
  only 
  previously 
  known 
  with 
  different 
  

   colonial 
  growth 
  — 
  for 
  instance, 
  Membranipora 
  cylindriformis 
  (?), 
  M. 
  

   appendiculata, 
  Stecjanoporella 
  perforata, 
  Oribrilina 
  monoceros, 
  Porina 
  

   larvalis, 
  Smittia 
  seriata, 
  Schizoporella 
  auriculata, 
  Smittia 
  anceps, 
  and 
  

   Mucronella 
  nitida 
  ; 
  while 
  the 
  two 
  stages 
  of 
  living 
  forms 
  are 
  known 
  

   •in 
  Steganoporella 
  inagnilabris, 
  Lepralia 
  foliacea, 
  Porella 
  concinna, 
  

   and 
  Smittia 
  reticulata. 
  We 
  have 
  also 
  seen 
  a 
  Catenicella 
  in 
  a 
  new 
  

   and 
  interesting 
  form, 
  besides 
  Crisia 
  without 
  joints. 
  

  

  If 
  the 
  old 
  classification 
  had 
  not 
  previously 
  been 
  discarded, 
  the 
  

   present 
  collections 
  would 
  by 
  themselves 
  have 
  shown 
  the 
  necessity 
  

   of 
  using 
  zocecial 
  before 
  zoarial 
  characters. 
  

  

  We 
  have 
  now 
  from 
  the 
  three 
  localities 
  127 
  determined 
  species 
  of 
  

   Chilostomata, 
  of 
  which 
  52 
  are 
  known 
  living 
  and 
  41 
  fossil 
  ; 
  14 
  are 
  

   considered 
  identical 
  with 
  European 
  Miocene 
  species, 
  17 
  with 
  

   Pliocene, 
  and 
  4 
  are 
  thought 
  to 
  be 
  identical 
  with 
  Cretaceous 
  species. 
  

  

  Having 
  completed 
  the 
  description 
  of 
  the 
  Chilostomata, 
  I 
  propose 
  

   next 
  to 
  deal 
  with 
  the 
  Cyclostomata 
  from 
  the 
  three 
  localities 
  in 
  one 
  

   communication.
