Coralliim an irregular mass, composed of prismatic corallites of rather 
unequal diameter. Tabulae horizontal, about half a millimetre apart ; mural 
pores small, rather close. 
Dimensions . — Diameter of the corallites varying from a half to one 
and a half millimetres. 
Dorizon and Localities . — A single specimen of this species has been 
found on the hanks of the Macleay Diver in a violet coloured rather compact 
limestone containing a large number of fragments of crinoid stems converted 
into white calcite. It has been found in the Devonian of the Eifel, Nehou, 
and Vire in Trance, of the Province of Leon in Spain, and in the State of 
Iowa in America.

Corallum dendroid, formed of branches one to two centimetres in 
diameter, and having the habit of bifurcating at various points of growth and 
in different directions. The corallites spring from the centre of each branch, 
and are directed obliquely and curving towards the periphery. Walls, thick ; 
calices, a little unequal, diameter about a millimetre. 
Horizon and Localities. — This species is very abundant in the Devonian 
of Eurojie. Several sjiecimens in rather bad preservation have been collected 
at Quedong, and another, very well preserved, near Yass. The first are found 
in a blackish argillaceous limestone, and the second in a pale-grey dolomite ; 
others again occur on the banks of the Murrumbidgee, Mowara, and Limekilns.
