   The

  with

  Bowerbank's 
  

   specimens.

  Fine 
  dry 
  examples 
  showing 
  the 
  cabbage-like 
  growth 
  characteristic 
  

   of 
  Hj'att's 
  genus. 
  Also 
  specimens 
  with 
  single 
  stem 
  (showing, 
  how- 
  

   ever, 
  traces 
  of 
  being 
  composed 
  of 
  two 
  or 
  more 
  united 
  axes) 
  and 
  

   simply 
  flabellar, 
  with 
  more 
  or 
  less 
  prominent 
  longitudinal 
  ridges 
  on 
  

   one 
  side, 
  sometimes 
  forming 
  secondary 
  flabellate 
  expansions. 
  The 
  

   specimens, 
  being 
  still 
  invested 
  with 
  dried 
  sarcode, 
  have 
  an 
  umber- 
  

   brown 
  colour 
  and 
  a 
  stiffness, 
  which 
  contrasts 
  strongly 
  with 
  the 
  

   very 
  pale 
  colour 
  and 
  the 
  flexibility 
  of 
  washed-out 
  specimens. 
  

  

  I 
  cannot 
  agree 
  with 
  Prof. 
  Ehlers 
  in 
  placing 
  this 
  sponge, 
  with 
  its 
  

   close 
  network, 
  under 
  Cacospomjia, 
  which 
  is 
  distinguished 
  by 
  the 
  

   loose 
  wide 
  meshes 
  formed 
  by 
  the 
  fibres.

  Cabbage-like 
  heads 
  formed 
  of 
  flabelliform 
  expansions, 
  which 
  fold 
  

   round 
  at 
  their 
  lateral 
  extremities, 
  which 
  then 
  may, 
  or 
  may 
  not, 
  

   unite 
  with 
  similar 
  fronds 
  which 
  arise 
  parallel 
  to 
  each 
  other 
  from 
  

   the 
  multi])le- 
  stalked 
  base 
  or 
  from 
  the 
  surfaces 
  of 
  other 
  fronds. 
  The 
  

   surface 
  of 
  the 
  skeleton 
  is 
  even, 
  without 
  projecting 
  ridges, 
  but 
  

   honeycombed 
  with 
  small 
  longitudinal, 
  coimected 
  by 
  short 
  hori- 
  

   zontal, 
  demi-canals, 
  between 
  which 
  intervene 
  small, 
  usually 
  lon- 
  

   gitudinally 
  elongate 
  ridges, 
  which 
  all 
  lie 
  on 
  one 
  level. 
  The 
  fibres 
  

   show 
  very 
  distinct 
  lamination 
  of 
  the 
  ceratinous 
  material 
  ; 
  both 
  pri- 
  

   mary 
  and 
  secondary 
  fibres 
  are 
  sand-cored, 
  but 
  the 
  sand 
  is 
  often 
  

   wanting 
  over 
  certain 
  areas 
  of 
  the 
  skeleton. 
  Represented
