diating from the centre irregularly, divided internally by simple transverse 
plates..^ — Carboniferous Limestone.

Linn. Syst. i. 1271 — Millepora liliacea, Pall. El. 248. — Millepora tu- 
bulosa, Sol. Ell. Zooph. 136 — -On corallines, common. 
The whole mass seldom exceeds half an inch in length, or the tenth of an inch 
in breadth ; the tubes, though usually united at the base, have the orifices 
free, and even in some cases are disjoined throughout ; a groove, destitute of 
cells, winds along the middle of the stem and branches ; the colour when re- 
cent has a purplish tinge.
