1. Caryophylla viola, nobis, n. sp. PI. V. fig. 1. 
Turbinolia viola, Woods, MS.* 
The coral is cuneiform and very compressed at the base, 
which is rounded inferiorly. The calice is elliptical and shallow. : 
The septa are delicate; the principal are exsert and rounded, 
having large lateral spiny granules. There are six systems of 
septa, and four cycles. The three first orders are nearly equal ; 
but the septa of the fourth and fifth orders are small, curve 
towards and touch the tertiary. The pali are tall rounded lobes 
on the tertiary septa; they are stout, larger than the end of the 
septa, and are sparsely granular. The columella is long and 
papillary. The costz are visible to the base, are slightly wavy | 
in their course, are separated by distinct grooves, and are of 
different lengths, those of the higher orders joining the others 
which reach to the base. All are visibly crenulate and faintly 
granular. 
In form the coral resembles a Sphenotrochus, the papille 
on the columella resemble those of Brachycyathus: the single 
row of pali and the distinct costee determine it to be one of the 
Caryophyllie ; but the absence of an epitheca is remarkable. It 
is a very beautiful form, and, without its calice, would be taken 
for an Eocene Turbinolian. 
Height 54, inch; length of calice =3, inch, width of calice 
25 inch. 
Locality.—Violet Creek, near Muddy Creek, South Australia. 
2. Flabellum Victoria, n.sp. PI. V. fig. 2. 
The coral presents a large basilar erosion, the result of the 
breaking-off of the peduncle: it has a sharp lateral spine on 
either side, which projects outwards and downwards, and which 
is situate immediately above the erosion. The coral is tall, 
compressed more below than above; its sides are slightly con- 
cave, and it is furnished with an epitheca which has faint trans- 
verse markings. The sides of the coral, were they produced 
towards the attachment, would form an angle of about 20°; 
they are rounded off, and only present the spine already noticed. 
The calice is elliptical ; the plane of the smaller axis is slightly 
higher than that of the larger ; the fossa is shallow, but centrally 
deep, narrow, and long, and the wall is thin. The septa are 
delicate, not exsert, are very slightly rounded, marked by large 
granules in series, and are unequal. There are four cycles in 
six systems, the primary and secondary septa being equal. 
There is no columella. The coste are not represented by the
