  ON 
  THE

  STOLICZKARIA. 
  

  

  and 
  in 
  time 
  for 
  publication, 
  sections 
  of 
  it 
  were 
  made 
  ; 
  and 
  it 
  then 
  

   became 
  evident 
  that, 
  had 
  I 
  attacked 
  this 
  specimen 
  first 
  of 
  all, 
  many 
  

   of 
  the 
  very 
  considerable 
  difficulties 
  which 
  attended 
  the 
  investigation 
  

   of 
  the 
  whole 
  group 
  would 
  have 
  been 
  lessened. 
  This 
  large 
  sphe- 
  

   roidal 
  specimen 
  turned 
  out 
  to 
  be 
  one 
  of 
  the 
  Syringosphaeridae 
  ; 
  but 
  

   its 
  structures 
  did 
  not 
  come 
  within 
  the 
  generic 
  idea 
  of 
  Syringosphceria. 
  

   Its 
  structure 
  was 
  remarkably 
  simple, 
  and 
  presented 
  many 
  micro- 
  

   scopic 
  beauties 
  of 
  detail. 
  

  

  The 
  form 
  was 
  placed 
  in 
  the 
  new 
  genus 
  StoliczJcaria. 
  

  

  Some 
  time 
  after 
  the 
  book 
  to 
  which 
  I 
  have 
  already 
  referred 
  was 
  

   published, 
  doubts 
  were 
  entertained 
  whether 
  the 
  Karakoram 
  stones 
  

   were 
  separable 
  from 
  that 
  group 
  of 
  great 
  spherical 
  and 
  spheroidal 
  

   Foraminifera 
  embracing 
  the 
  genera 
  Parleria 
  and 
  Loftusia, 
  which 
  was 
  

   so 
  ably 
  described 
  by 
  Dr. 
  Carpenter 
  and 
  Mr. 
  Brady 
  in 
  the 
  Phil. 
  

   Trans.*

  The 
  shape 
  of 
  many 
  of 
  the 
  specimens 
  of 
  the 
  

   Syringosphaeridae 
  was 
  noticed 
  to 
  be 
  the 
  same 
  as 
  that 
  of 
  ParJceria 
  ; 
  

   and 
  the 
  similarity 
  of 
  the 
  external 
  ornamentation 
  was 
  in 
  some 
  in- 
  

   stances 
  very 
  great, 
  to 
  the 
  naked 
  eye. 
  

  

  Although 
  the 
  distinctness 
  of 
  the 
  Indian 
  and 
  English 
  forms 
  was 
  

   always 
  evident 
  to 
  me, 
  and 
  the 
  non-arenaceous 
  nature 
  of 
  the 
  inner 
  

   parts 
  of 
  the 
  Syringosphaeridae 
  was 
  without 
  doubt, 
  I 
  felt 
  the 
  necessity 
  

   of 
  very 
  carefully 
  reconsidering 
  my 
  work 
  and 
  decisions, 
  especially 
  

   as 
  specimens 
  of 
  ParJceria 
  have 
  been 
  lent 
  me 
  by 
  Prof. 
  H. 
  G. 
  Seeley, 
  

   F.R.S., 
  and 
  Dr. 
  Millar, 
  F.G.S., 
  the 
  fossilization 
  of 
  which 
  is 
  mainly 
  

   calcareous, 
  and 
  as 
  in 
  some 
  of 
  the 
  doubtful 
  fossils 
  interspaces 
  exist. 
  

  

  The 
  following 
  are 
  the 
  diagnoses 
  of 
  the 
  order 
  Syringosphaeridae, 
  and 
  

   of 
  the 
  genera 
  SyringospJiceria 
  and 
  StoliczJcaria. 
  

  

  Order 
  SYRINGOSPH^RID^.f 
  

  

  Body 
  free, 
  spherical 
  or 
  spheroidal 
  in 
  shape, 
  consisting 
  of 
  numbers 
  

   of 
  limited 
  more 
  or 
  less 
  conical 
  radiating 
  congeries 
  of 
  minute, 
  

   continuous, 
  long, 
  bifurcating 
  and 
  inosculating 
  tubes 
  ; 
  also 
  of 
  an 
  

   interradial 
  close 
  or 
  open 
  tube-reticulation 
  arising 
  from 
  and 
  sur- 
  

   rounding 
  the 
  radial 
  congeries. 
  Tubes 
  opening 
  at 
  the 
  surface 
  on 
  

   eminences 
  and 
  in 
  pores, 
  and 
  ramifying 
  over 
  it. 
  Tubes 
  minute, 
  

   consisting 
  of 
  a 
  wall 
  of 
  granular 
  and 
  granulo-spiculate 
  carbonate 
  of 
  

   lime. 
  Coenenchyma 
  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 
  reticu- 
  

   lation 
  in 
  the 
  poreless 
  kinds, 
  necessitate 
  the 
  division 
  of 
  the 
  order 
  into 
  

   two 
  genera. 
  

  

  Genus 
  Syringospeleria. 
  

  

  Body 
  large, 
  symmetrical, 
  nearly 
  spherical 
  or 
  oblately 
  spheroidal, 
  

   covered 
  with 
  large 
  compound 
  wart-like 
  prominences 
  with 
  inter- 
  

   mediate 
  verrucosities, 
  or 
  with 
  compound 
  monticules 
  having
