The largest portions of the calcareous cylinder of the fossil 

 are 3-4 mm. long and 2 mm. thick, but they were probably 

 10 mm. long -when alive. They are perfectly cj'liudrical or 

 slightly compressed. The tubes are penetrated by a central 

 cavity which varies from l'2-l-4 mm. in diameter. The wall is 

 often as much as 0'5 mm. thick, and is penetrated by numerous 

 radially arranged branches of two kinds, the one simple and 

 uniform, about 0-0.5-0-06 mm. in diameter, and the other in 

 fewer numbers and of flask-like shape with a blind ending.
