Corallum a snbgloboso or lobate mass. Corallites practically equal, 
very small, prismatic, only a third of a millimetre in diameter, radiating from 
the base to the surface, and curving slightly and increasing by interposition. 
Mural pores very close, arranged in single vertical series on the angles of the 
prisms, and only visible by means of a magnifying glass. 
Horizon and Localities. — This species seems to have appeared before the 
deposition of the lower beds ol the Silurian in which it is found in England, 
and to have survived till the formation of the Middle Devonian, where it 
occurs in the Eifel. Two of the specimens collected by the Eev. W. [B.] 
Clarke appear to me to be Devonian, one being associated with Campopliytlum 
fiexuosum, Goldfuss, and the other with Strophalosia productoides. They 
occur at Quedong; a third, probably Silurian, has been found at Yarralumla.
