  I 
  am 
  in 
  doubt 
  as 
  to 
  the 
  generic 
  position 
  of 
  this 
  species 
  ; 
  but 
  it 
  

   seems 
  clearly 
  to 
  be 
  related 
  to 
  the 
  fossil 
  from 
  South-west 
  Victoria, 
  as 
  

   the 
  mouth 
  is 
  similar 
  in 
  shape 
  and 
  about 
  the 
  same 
  size, 
  with 
  the 
  small 
  

   avicularia 
  in 
  the 
  mouth, 
  and 
  with 
  similar 
  large 
  lateral 
  zocecial 
  

   avicularia. 
  The 
  three 
  or 
  five 
  large 
  pores 
  remind 
  us 
  of 
  Mucronella 
  

   mucronata-, 
  and 
  Eschar 
  a 
  Liver 
  sidgei, 
  "Woods, 
  may 
  belong 
  to 
  either 
  of 
  

   these 
  species.

  In 
  many 
  specimens 
  the 
  large 
  depressed 
  area 
  is 
  absent 
  ; 
  and 
  in 
  

   consequence 
  of 
  the 
  state 
  of 
  fossilization 
  I 
  cannot 
  always 
  see 
  any 
  

   Microporellidan 
  pore. 
  There 
  is 
  often 
  only 
  one 
  suboral 
  avicularium. 
  

  

  I 
  am 
  unable 
  to 
  agree 
  with 
  Mr. 
  Hincks 
  in 
  thinking 
  that 
  Eschara 
  

   lichenoides, 
  Busk, 
  is 
  identical 
  with 
  E. 
  mucronata, 
  MacGill., 
  though 
  

   the 
  figure 
  of 
  the 
  last 
  is 
  so 
  unsatisfactory 
  that 
  I 
  am 
  by 
  no 
  means 
  sure 
  

   what 
  it 
  really 
  represents, 
  and 
  it 
  may 
  be 
  M. 
  coscinopora 
  or 
  violacea. 
  

  

  The 
  size 
  of 
  the 
  aperture 
  should 
  of 
  course 
  be 
  0-06 
  millim. 
  wide, 
  

   not 
  0*6 
  millim. 
  wide 
  as 
  previously 
  printed.
