base ; the base is moderately large, and presents evidences of 

 attachment to some substance during life ; there is a slight con- 

 striction above the base ; the epitheca is imperfect, and surrounds 

 the corallum here and there in many lines ; the costee are dis- 

 tinct, wide, equal, and covered with spiny granulations ; they are 

 more or less continued over the small lateral wing-like projec- 

 tions ; the calice is elliptical in its outline, shallow, and with a 

 sharp, narrow, and slightly cellular margin ; the columella is 

 large, long, and spongy ; the septa are unequal, not exsert, stout 

 and granular ; there are four cycles of septa in six systems ; the 

 septa of the first, second and third orders reach the columella, 

 and those of the higher curve towards and meet the tertiary 

 midway between the wall and the columella. Height of corallum 

 1 2 -10th inch, breadth of calice \ inch. 

 Locality : Hamilton Tertiaries, Victoria. 



Balanophyllia selwyni, Duncan. 



The corallum is subcylindrical and slightly compressed, and 

 has a large base with a slight constriction above it ; the costae 

 are distinct, flat above and rounded midway, and below finely 

 granular superiorly, and marked with one series of large granules 

 inferiorly ; the epitheca is absent ; the wall is moderately 

 developed ; the columella is large and long ; the septa are very 

 stout ; there are four cycles of septa, in six systems, and the 

 higher orders unite with the tertiary at about one-fourth of the 

 distance from the wall to the columella ; the calice is com- 

 pressed and elliptical. Height 1 inch, greatest length of the 

 calice J inch. 



Locality : No. 3, upper coralline beds, near C. Otway, Victoria. 



Balanophyllia fragilis, Duncan. 



The corallum is long and conico-cylindrical in shape, twisted 

 and curved ; the epitheca is quite rudimentary, in the form of 

 slight transverse bands ; the costae are flat and marked with one 

 series of small, distinct, sharp, spiny granules, or with a ridge ; 

 the wall is very thin and hardly cellular ; the columella is very
