The diameters of the largest calice are 13 mm. and 10 mm.; 
and of the smallest, 9 mm. and 8 mm. respectively. 
Locality, ete.—From a well-sinking in the Murray Desert. 
The coral was sent to the late Professor Tate, who, after some 
trouble, identified the locality as Mindarie, 80 miles south- 
east of Swan Reach, Murray River. The age of the fossils 
accompanying it is given in Professor Tate’s memoir as 
Post-Eocene (? Oligocene).*

The corallum is pedicellate, tapering, and curved or twist- 
ed. Some examples have occasional warts or excrescences 
on their surface. The wall is stout and smooth, and rarely 
shows the remains of a banded epitheca: at the summit only 
а few созбе appear as continuations of the principal septa. 
A specimen lately collected has the base of one corallum 
attached to the calice of another, with its columella and half 
the septa still free. This, however, is merely a case of acci- 
dental adhesion. 
The calice is circular and deeply excavated. Тһе colum- 
ella is large, spongy, and reaches high up in the calice. The 
septa are sparsely granular, and in ten systems, with three 
cycles. The primaries are long, stout, and wavy; for a 
short distance from the margin they are horizontal, and 
then descend vertically in the fossa, a clear space being left 
between them and the columella. The secondaries are thin- 
ner, less conspicuous, also wavy, and pass into the fossa 
nearer the margin; the tertiaries are very slender lamellæ. 
Endotheca scanty; in the type specimen there is apparently 
none, but it is certainly present in some others. 
Height, 14 mm. ; diameter of calice, 6 mm.

The coralla vary both in shape and size. Some are 
straight and conico-cylindrical, or vase shaped, while others 
are slightly bent and of nearly the same circumference 
throughout. Again, there are moderately tall as well as 
short examples. The pedicellate base is large and is fre- 
quently still attached to a fragment of shell. The wall is 
stout, and is covered by a white, shining epitheca, which
