  The

  exhibits 
  signs 
  of 
  incipient 
  formation 
  of 
  a 
  cup, 
  

   and 
  thus 
  shows 
  Esper

  the

  approximately

  Bowerbank's 
  description 
  of 
  the 
  vents 
  is 
  unsatisfactory. 
  

  

  The 
  skeleton 
  contains 
  much 
  less 
  sand 
  than 
  Bowerbank's 
  specimen, 
  

   but 
  agrees 
  with 
  it 
  in 
  the 
  general 
  characters 
  of 
  the 
  skeleton, 
  the 
  

   differences 
  being 
  to 
  some 
  extent 
  due 
  to 
  age. 
  As 
  stated 
  in 
  the 
  

   Report 
  on 
  the 
  Australian 
  collections, 
  this 
  species 
  agrees 
  essentially 
  

   with 
  the 
  characters 
  of 
  Carterispongia. 
  The 
  colour 
  (in 
  spirit) 
  is 
  

   greyish 
  brown 
  outside", 
  dirty

  This 
  species 
  varies 
  in 
  outward 
  form 
  from 
  contort 
  flabellate, 
  with 
  

   single 
  thick 
  stem, 
  to 
  compound, 
  multicaulate, 
  anastomosing, 
  with 
  

   thin 
  stems, 
  the 
  terminal 
  fronds 
  narrower 
  or 
  broader 
  flabelliforfti. 
  

   In 
  much-washed 
  specimens 
  the 
  surface 
  has 
  an 
  eroded 
  appearance, 
  

   from 
  the

  the 
  canal-s5"stem,
