  transverse

  which 
  suggest 
  a

  of 
  the 
  

   same 
  corresponding 
  to 
  that 
  of

  the 
  first 
  order 
  are 
  always 
  arranged 
  in 
  pairs. 
  Their 
  base 
  is 
  some- 
  

   what 
  swollen 
  and 
  also 
  articulates 
  with 
  the 
  main 
  branch. 
  The 
  

   branchlets 
  of 
  the 
  first 
  order 
  are 
  long 
  and 
  slender. 
  They 
  bear 
  

   a 
  whorl 
  of 
  four 
  or 
  more 
  shorter 
  branchlets 
  of 
  the 
  second 
  order 
  

   and 
  each 
  of 
  these 
  again 
  four 
  (or 
  more) 
  short 
  bulbous 
  termi- 
  

   nal 
  branchlets 
  in 
  the 
  specimen 
  figured. 
  In 
  others 
  these 
  are 
  again- 
  

   seen 
  to 
  grow 
  out 
  to 
  branchlets 
  of 
  the 
  length 
  of 
  those 
  of 
  the 
  

   preceding 
  order. 
  No 
  traces 
  of 
  fructification 
  could 
  be 
  found.

  is 
  clearly 
  algal 
  and 
  there 
  are 
  a 
  

   number 
  of 
  recent 
  genera, 
  especially 
  among 
  the 
  Florideae, 
  with 
  

   which 
  it 
  could 
  be 
  readily 
  compared 
  in 
  this 
  respect. 
  Its 
  branching 
  

   is 
  verticillate 
  in 
  the 
  distal 
  parts 
  and 
  therefore 
  invites 
  comparison 
  

   rather 
  with 
  forms 
  other 
  than 
  Callithamnion 
  which 
  is 
  typically 
  

   represented 
  by 
  bifurcating 
  forms. 
  The 
  mode 
  of 
  branching 
  and 
  

   general 
  structure 
  is 
  so 
  mudi 
  like 
  that 
  of 
  the 
  preceding 
  genus, 
  

   Primicorallina, 
  that 
  Callithamnopsis 
  could 
  be 
  considered 
  as 
  a 
  closely 
  

   related 
  form 
  lacking 
  the 
  incrustation 
  of 
  carbonate 
  of 
  lime.
