ginal  halten.  Eine  solche  vorzunehmen  wagen  wir  aber  nicht,  da  uns 
von  Syringosphaeria  keine  Abbildung  vorliegt  und  die  Ausdrucksweise  des 
Verfassers  so  ist,  dass  Missverständnisse  ohne  Vergleich  einer  guten  bild-

Order  Syringosphaeridae. 
Body  free,  spherical  or  spheroidal  in  shape,  consisting  of  numbers  of 
limited  more  or  less  conical  radiating  congeries  of  minute,  continous,  long, 
bifurcating  and  inosculating  tubes;  also  of  an  interradial  close  or  open 
tube  reticulation  arising  from  and  surrounding  the  radial  congeries.  Tubes 
opening  at  the  surface  on  eminences  and  in  pores,  and  ramifying  over  it. 
Tubes  minute,  consisting  of  a  wall  of  granulär  and  granulo-spiculate  car- 
bonate  of  lime.    Conenchym  absent. 
The  presence  of  pores  on  the  surface  of  some  forms  of  the  Order, 
and  their  absence  in  others,  and  the  nature  of  the  interradial  reticulation 
in  the  poreless  kinds,  necessitate  the  division  of  the  order  into  two  genera. 
Genus  Syringosphaeria. 
Body  large,  symmetrical,  nearly  spherical  or  oblately  spheroidal, 
covered  with  large  Compound  wart  like  prominences  with  intermediate 
verrucosities,  or  with  Compound  monticules  having  rounded  summits,  with 
solitary  eminences  between  them,  or  with  close  broadly  rounded  tubercles, 
or  with  minute  granulations.  Rounded  or  oblique  or  linear  depressions 
occur  on  the  surface,  usually  between  the  eminences,  but  sometimes  upon 
them,  they  are  shallow  and  are  bounded  by  tubes  opening  on  it  from 
the  internal  radial  series,  and  also  from  the  interradial  tube  reticulation, 
also  masses  of  tubes  running  over  it,  converying  on  the  eminences,  and 
more  or  less  reticulate  elsewhere. 
Radial  congeries  of  tubes  numerous  and  defined;  and  the  interradial 
tubulation  is  open  or  close  and  varicose. 
Genus  StoliczTcaria. 
Body  very  large,  symmetrical,  oblately  sphaeroidal,  covered  with  a 
great  number  of  minute  distinct  granulations ,  which  are  circular  at  the 
base,  short  and  rather  flat  where  free,  and  which  are  separated  by  an 
amount  of  surface  about  equal  to  their  breadth.  No  pores  exist.  Tube 
openings  occur  on  granulations;  and  tubes,  with  or  without  openings, 
converge  to  their  surface  and  cover  the  intermediate  surface.  The  tubes 
opening  unto  the  centre  of  the  surface  of  the  granulations  and  termi- 
nations  of  the  very  numerous  radial  series,  and  are  small ;  and  the  others, 
which  are  larger,  belong  to  the  closely  packed  varicose  and  much  con- 
torted  interradial  series.  The  body  within  consists  of  a  vast  number  of 
small,  not  very  conical,  but  rather  straight,  radial  series,  whose  rather 
distant  tubes  give  off  minute  offshoots  to  the  surrounding  convoluted  and 
varicose  large  tubes  of  the  close  interradial  series.  No  coenenchyma  can 
be  discovered. 
Wegen  der  Gleichheit  der  Form  und  des  Vorhandenseins  eines  Systems 
radialer  Röhren  liegt  ein  Vergleich  mit  ParJceria  nahe.  Der  Verfasser 
legt  jedoch  auf  die  mehr  labyrinthische,  nicht  röhrenartige  Structur  der
