  The 
  annelids, 
  or 
  typical 
  worms, 
  are 
  soft-bodied, 
  marine, 
  fresh- 
  

   water 
  or 
  terrestrial 
  animals, 
  whose 
  remains 
  can 
  seldom 
  be 
  preserved 
  

   in 
  a 
  fossil 
  state. 
  It 
  is 
  only 
  the 
  tube-building 
  order 
  (Tubicola) 
  that 
  

   leaves 
  any 
  satisfactory 
  remains. 
  In 
  these 
  the 
  tube 
  is 
  either 
  a 
  cal- 
  

   careous 
  secretion 
  of 
  the 
  animal 
  or 
  is 
  composed 
  of 
  agglutinated 
  sand 
  

   and 
  other 
  foreign 
  particles, 
  being, 
  in 
  each 
  case, 
  wholly 
  external. 
  

   Worm 
  burrows 
  are 
  often 
  preserved 
  by 
  sand 
  or 
  mud 
  infiltration, 
  a 
  

   cast 
  of 
  the 
  burrow 
  appearing 
  in 
  the 
  strata.

  Class 
  BRYOZOA 
  Ehrenberg 
  

  

  The 
  Bryozoa, 
  or 
  Polyzoa, 
  are 
  marine 
  or 
  fresh-water 
  invertebrates, 
  

   almost 
  always 
  occurring 
  in 
  colonies 
  or 
  zoaria 
  which 
  increase 
  by 
  

   gemmation. 
  Each 
  jjooid 
  'of 
  the 
  colony 
  is 
  inclosed 
  in 
  a 
  membranace- 
  

   ous, 
  or 
  calcareous, 
  double-walled 
  sac, 
  the 
  zooccmm, 
  into 
  which 
  it 
  can 
  

   withdraw. 
  The 
  animal 
  possesses 
  a 
  mouth, 
  an 
  aHmentary 
  canal 
  and 
  

   an 
  anal 
  opening, 
  and, 
  in 
  addition 
  to 
  these, 
  a 
  fringe 
  of 
  respiratory
