23. BALANOPHYLLIA CYLINDRICA, Michel, sp., variety a. Plate XXI. 
fig. 7 
The corallum is cylindro-turbinate and curved at the base, which 
is not pedicellate, but sharp. The calice is large, shallow, and very 
open. The epitheca is complete and covers the faintly distinguish- 
able costee. The wall is moderately stout and cellular. The columella 
is moderately developed. The septa are stout; and there are four 
cycles, in six systems: the higher orders unite with the tertiary about 
midway. 
Height of corallum 20 inch. Breadth of calice ;4, inch. 
Locality. No. 1, 14 mile west of Cape Otway. 
Variety (3. Corallum more slender and columella larger than in 
variety a; the same locality. 
24, BatanopuyLiia Uricui, n. sp. Plate XXI. fig. 8. 
The corallum is cylindro-conical, slightly curved, and has a small 
peduncle and a large open calice. The epitheca is dense and complete 
inferiorly ; but above, the coste are uncovered and are well marked, 
equal, rather prominent, separate, and finely granular. The colu- 
mella is small. The septa are slender ; and there are four cycles, in 
six systems. The OSE is deep, and the margin thin. 
Height of corallum =§, inch. Breadth of calice 53, inch. 
Locality. INO, Tks tle ‘mile west of Cape Otway, South Australia. 
25. BALANOPHYLLIA TUBULIFORMIS, n. sp. Plate XXI. fig. 9. 
The corallum is tall, cylindrical, and tubular in shape. There is 
no epitheca. The coste are equal, flat, vermiculate, and separated 
by distinct spaces. The calice is circular in outline, rather less in 
calibre at the margin than elsewhere, very deep, and it has a wide 
margin. The wall is stout and cellular. The columella is small, 
and at the bottom of the deep fossa. The septa are stout, and very 
granular; and there are four cycles, in six systems. There is a very 
slight in-bending of the higher orders; and the septal arrangement 
has very little of the JSiersinaneadena type. 
‘Height of the corallum 58, inch. Breadth of the calice 5%, inch.

26. AMPHIHELIA INCRUSTANS, n. sp. Plate XX. fig. 6 
The corallum is flat and incrusting, and the calices arise like 
crateriform processes. The upper surface is irregular and marked 
with wavy, subequal, bifurcating costee, which pass upwards on the 
outside of the calice more or less obliquely. The calice is crateriform ; 
the margin is sharp, and the fossa is shallow. The septa are smaller 
than the costs, and not exsert ; there are three cycles, in six systems, 
and a few orders of the fourth cycle. The columella is small and 
projecting, 
Breadth of the calice 3, inch. 
Locality. No. 3, Upper “‘ Coralline beds,” near Cape Otway.
