  Each

  is 
  supported 
  on 
  the 
  fascicles 
  of 
  the 
  

   inferior 
  lamella, 
  serving 
  as 
  pillars; 
  it 
  is 
  formed 
  of 
  distinct 
  subcolonies 
  

   in 
  the 
  form 
  of 
  Actinopora

  of

  joined 
  

   together. 
  Each 
  of 
  the 
  subcolonies 
  has 
  a 
  distinct 
  origin 
  and 
  arises 
  

   from 
  a 
  tube 
  of 
  a 
  fascicle 
  of 
  the 
  inferior 
  lamella. 
  

  

  The 
  section 
  figured 
  by 
  D'Orbigny

  incomplete, 
  for 
  it 
  does 
  not 
  

   cut 
  the 
  basal 
  portion 
  of 
  a 
  subcolony 
  and 
  therefore 
  does 
  not 
  show- 
  

   exactly 
  the 
  formation 
  of 
  the 
  zoarium. 
  A 
  section 
  properly 
  made 
  shows 
  

   that 
  the 
  tubes 
  are 
  cylindrical, 
  with 
  

   dorsal 
  gemmation, 
  vertically 
  elevated. 
  

  

  The 
  fascicles 
  are 
  irregular, 
  ovoid, 
  

   rather 
  short, 
  irregularly 
  multiserial.

  MULTIGALEA, 
  new 
  genus 
  

  

  The 
  ovicell 
  is 
  elongate, 
  star-shaped, 
  with 
  many 
  branches; 
  the 
  

   branches 
  are 
  separated 
  by 
  uni- 
  or 
  biserial 
  groups 
  of 
  zooecia. 
  The 
  

   tubes 
  have 
  an 
  exterior, 
  triangular, 
  very 
  fragile 
  visor 
  ( 
  = 
  galea) 
  . 
  The 
  

   tubes 
  are 
  cylindrical, 
  with 
  dorsal 
  gemmation, 
  elevated 
  in 
  their 
  su- 
  

   perior 
  half. 
  The 
  zoarium 
  is 
  composed 
  of 
  orbicular 
  subcolonies 
  irreg- 
  

   ularly 
  superposed. 
  The 
  cancelli 
  are 
  small 
  and 
  denticulated 
  in 
  the 
  

   interior.

  This 
  

   new 
  genus 
  differs 
  from 
  Radiopora 
  D'Orbigny, 
  1849, 
  in 
  the 
  presence 
  of 
  

   ovicells 
  and 
  in 
  the 
  occurrences 
  of 
  visors 
  on 
  the 
  tubes.
