  — 
  This 
  species 
  is 
  very 
  well 
  characterized 
  not 
  only 
  by 
  its 
  

   concave 
  tubes 
  but 
  also 
  by 
  its 
  frontal 
  ornamentation 
  and 
  especially 
  

   by 
  its 
  small 
  salient 
  threads 
  arranged 
  in 
  quincunx.

  This 
  genus 
  is 
  still 
  little 
  understood. 
  The 
  published 
  sections 
  are 
  

   not 
  in 
  accord, 
  and 
  those 
  which 
  we 
  give 
  are 
  still 
  somewhat 
  different. 
  

   We 
  have 
  not 
  been 
  fortunate 
  enough 
  to 
  discover 
  the 
  ovicell. 
  The 
  

   anastomosing 
  lines 
  which 
  ornament 
  the 
  surface 
  and 
  form 
  the 
  chief 
  

   generic 
  characterictic 
  seem 
  to 
  correspond 
  only 
  to 
  parietal 
  thickenings.

  Description. 
  — 
  The 
  zoarium 
  is 
  free, 
  cylindrical, 
  bifurcated 
  in 
  the 
  

   same 
  plane. 
  The 
  tubes 
  are 
  visible, 
  separated 
  by 
  salient 
  threads 
  di- 
  

   vided 
  into 
  four 
  parts 
  by 
  other 
  anastomosing 
  threads. 
  The 
  orifice 
  is
