  Bryozoiim 
  solid, 
  ramose 
  ; 
  branches 
  frequent 
  and 
  not 
  widely 
  

   diverging 
  ; 
  diameter 
  from 
  1.5 
  to 
  2 
  mm. 
  Cell-tubes 
  polygonal, 
  

   arising 
  from 
  the 
  center 
  of 
  the 
  branch 
  and 
  gradually 
  diverging 
  

   till 
  within 
  half 
  a 
  millimetre 
  of 
  the 
  surface 
  when 
  they 
  turn 
  

   abruptly 
  outward 
  ; 
  at 
  the 
  point 
  of 
  turning, 
  the 
  cell-walls, 
  

   previously 
  thin, 
  become 
  thickened. 
  Xo 
  transverse 
  septa 
  are 
  

   visible 
  till 
  near 
  the 
  surface, 
  where 
  they 
  are 
  numerous 
  and 
  dist- 
  

   ant 
  from 
  each 
  other 
  about 
  the 
  width 
  of 
  the 
  cell- 
  tubes. 
  Cell 
  

   apertures 
  variable 
  in 
  size, 
  the 
  larger 
  ones 
  being 
  about 
  .16 
  mm. 
  

   in 
  diameter, 
  irregularly 
  arranged 
  and 
  having 
  short, 
  stout 
  spin- 
  

   ules 
  at 
  the 
  angles. 
  

  

  This 
  species 
  is 
  readily 
  distinguished 
  by 
  its 
  solid 
  aspect, 
  

   minute 
  cells 
  which 
  are 
  variable 
  in 
  size, 
  and 
  the 
  compara- 
  

   tively 
  strong 
  spinules 
  which 
  disguise 
  the 
  cell-apertures 
  and 
  

   give 
  a 
  uniform 
  asperate 
  aspect 
  to 
  the 
  surface. 
  Sometimes 
  the 
  

   cell-margins 
  are 
  worn 
  flat 
  and 
  the 
  cells 
  appear 
  oval. 
  It 
  differs 
  

   from 
  T. 
  ecliinata 
  in 
  its 
  more 
  robust 
  aspect, 
  and 
  the 
  smaller 
  

   and 
  less 
  elongate 
  cells. 
  

  

  CALLOPOEA 
  Hall. 
  

  

  I 
  continue 
  the 
  use 
  of 
  the 
  name 
  Callopoea. 
  which 
  is 
  claimed 
  

   by 
  some 
  authors 
  to 
  be 
  identical 
  with 
  Fistulipoea 
  of 
  McCoy, 
  

   for 
  the 
  reason 
  that 
  the 
  author 
  of 
  the 
  latter 
  genus 
  (British 
  

   Palceozoic 
  Fossils, 
  p. 
  11) 
  says 
  that 
  •* 
  this 
  genus 
  was 
  proposed 
  

   to 
  include 
  the 
  Mdnon 
  criorosum 
  (Gold.) 
  of 
  the 
  Eifel, 
  &c, 
  

   and 
  some 
  new 
  species." 
  The 
  JIanon 
  criorosum 
  of 
  Goldfuss 
  

   is 
  recognized 
  by 
  European 
  palaeontologists 
  as 
  a 
  specimen 
  of 
  

   Helioiites 
  inter 
  stincta 
  . 
  Again, 
  in 
  describing 
  F. 
  decipiens. 
  

   the 
  author 
  says 
  : 
  "So 
  exactly 
  does 
  this 
  resemble 
  the 
  Palceo- 
  

   poro. 
  inter 
  -stincta," 
  etc. 
  The 
  figures 
  of 
  F. 
  decipiens 
  scarcely 
  

   resemble 
  Callopoea 
  in 
  its 
  ordinary 
  forms. 
  See 
  Descriptions 
  

   of 
  Lower 
  Helderberg 
  Corals 
  and 
  Bryozoa 
  for 
  further 
  obser- 
  

   vations 
  on 
  these 
  genera.
