338 THE PROCEEDINGS OF THE LINNEAN SOCIETY 



there are four cycles in six systems ; the fossa is deep and the 

 margin thin. Height of corallum 6-1 Oth inch, breadth of calice 

 3-10th inch. Locality No. 1, 1| mile west of Cape Otway, -Vic- 

 toria. 



Balanophyllia tubuliformis, Duncan. 



The corallum is tall, cylindrical, and tubular in shape ; there 

 is no epitheca ; the costae are equal, flat, vermiculate, and sep- 

 arated 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 arrangment has very little of the Eupsammian type. 

 Height of the corallum, 6-10th inch; breadth of the calice, 3-10th 

 inch. Locality : Muddy Creek, Hamilton Tertiaries, Victoria. 



Balanophyllia campanulata, Duncan. 



The corallum is pedicellate, has a slight constriction imme- 

 diately above the small base, and expands regularly into an 

 elongate bell-shape ; the epitheca exists inferiorly, but it is very 

 delicate and permits the flat costae to be distinguished ; the calice 

 is elliptical, and the margin is slightly everted ; the wall is 

 moderately developed ; the columella is large, long, spongy, and 

 prominent ; the septa are stout ; there are four cycles ; and the 

 septa of the fourth and fifth orders unite with the tertiary mid- 

 way between the wall and the columella ; the tertiary septa, after 

 the junction with the orders, are as large as the primary and 

 secondary septa; the laminae are granular; the costae, where un- 

 covered, are separated by distinct intercostal spaces with numerous 

 foramina ; they are slightly unequal, and have both granulations 

 and foramina on their flat external surface ; there are rarely more 

 than two rows of granules, and they are scarce. Height of 

 the corallum, 8-10th inch ; breadth of calice, 3-10th inch. Loca- 

 lity No. 4, clay beneath " coralline beds," near Cape Otway. It 

 is associated with Trigonia semiundulata.
