  with 
  an 
  avicularium 
  in 
  the 
  mouth 
  and 
  punctured 
  all 
  over 
  the 
  

   surface, 
  the 
  other 
  as 
  fig. 
  3 
  ; 
  and 
  within 
  the 
  last 
  few 
  days 
  Miss 
  

   Jelly 
  has 
  sent 
  me 
  a 
  specimen 
  of 
  this 
  last, 
  which 
  she 
  found 
  in 
  her 
  

   collection 
  from 
  S.W. 
  Victoria. 
  It 
  is 
  better 
  preserved 
  than 
  the 
  

   others, 
  showing 
  the 
  acute 
  shape 
  of 
  the 
  small 
  avicularia, 
  which 
  point 
  

   downwards 
  ; 
  and 
  there 
  are 
  also 
  ovicells 
  preserved, 
  which 
  are 
  very 
  

   little 
  raised. 
  The 
  shell-structure 
  of 
  the 
  central 
  part 
  of 
  the 
  ovicell 
  

   is 
  much 
  thinner 
  than 
  the 
  front 
  wall 
  of 
  the 
  zocecia 
  ; 
  and 
  this 
  thinner 
  

   part 
  is 
  surrounded 
  by 
  a 
  broad 
  band. 
  

  

  The 
  ovicells 
  of 
  L. 
  foliacea 
  seem 
  seldom 
  to 
  have 
  been 
  found 
  ; 
  and 
  as 
  

   in 
  this 
  case 
  they 
  are 
  less 
  raised 
  than 
  in 
  my 
  Naples 
  specimens, 
  and 
  

   are 
  also 
  surrounded 
  by 
  a 
  broad 
  border, 
  it 
  must 
  be 
  looked 
  upon 
  as 
  a 
  

   distinct 
  variety 
  ; 
  or 
  possibly 
  it 
  will 
  have 
  to 
  be 
  specifically 
  separated.

  The 
  separating 
  lines 
  between 
  the 
  zocecia 
  are 
  much 
  raised 
  ; 
  and 
  as 
  

   the 
  colony 
  is 
  fertile, 
  it 
  has 
  much 
  more 
  the 
  appearance 
  figured 
  by 
  

   MacGillivray 
  than 
  the 
  specimen 
  from 
  S.W. 
  Victoria. 
  The 
  surface 
  

   is 
  coarsely 
  granular 
  ; 
  and 
  the 
  raised 
  ovicell 
  occupies 
  the 
  greater 
  part 
  

   of 
  the 
  front 
  of 
  the 
  zocecium.

  The 
  zoaria 
  from 
  Bairnsdale 
  consist 
  of 
  hollow 
  cylinders 
  about 
  

   3 
  mm. 
  in 
  diameter. 
  In 
  some 
  specimens 
  the 
  zocecia 
  form 
  transverse 
  

   series, 
  in 
  others 
  they 
  are 
  alternate— 
  showing 
  that 
  the 
  fact 
  of 
  the 
  

   zocecia 
  being 
  arranged 
  transversely 
  cannot 
  be 
  made 
  a 
  specific 
  cha- 
  

   racter, 
  much 
  less 
  generic, 
  as 
  was 
  done 
  with 
  Melicerita. 
  It 
  is 
  still 
  a 
  

   character 
  used 
  in 
  classifying 
  the 
  Cyclostomata.
