There is no cther union of septa in the calice, the primaries 
and secondaries being straight and free. The edges of both 
these orders slope gradually for a short distance from the 
wall, and then, like the tertiaries, they descend vertically in 
the fossa. They do so, however, much nearer the margin, 
and thus at a comparatively high level in the calice. 
Height of соға аш, 21 mm.; length of calice, 10:5 mm.; 
breadth of do., 9 mm. 
Locality, etc.—Very rare in the Eocene strata of Cape 
Otway. Two examples. 
This species is allied to В. tubuliformis, Duncan, from 
which it is distinguished by its banded epitheca, slender 
septa, elliptical calice, and curved outline.

The corallum is straight, subturbinate, slightly compressed, 
moderately tall, broad at the summit, and then 
tapering to a tumid pedicellate base. The whole 
surface is  vermiculate and granular, the granules 
being most prominent on the broad, equal, raised 
coste. These project at the summit, and slightly overlap 
the calicular margin, where their correspondence with the 
septa is well marked. The wall is highly porous, and so thin 
as to appear translucent when viewed against the light. 
There is no epitheca. 
The calice has a vermiculate margin, is shallow, widely 
open, and subelliptical. The septa are siender, porous, granu- 
lar, and occasionally spined. They are in six systems, with 
four complete cycles. The tertiaries are by far the most 
conspicuous septa in the calice. For about one-half from the 
wall they are small and thin, when they are joined by the 
higher orders, which curve towards them. At this junction, 
or a little above it, they rise as large, stoutish, very pro- 
minent fans, with spined and jagged edges, and continue to 
the columella. There are thus twelve tertiary fans in the 
calice, of which the eight opposite the sides are larger than 
the four at the ends. The two fan-iike tertiary septa in 
each system curve round at their inner ends and unite in 
front of the enclosed straight secondary, which, though 
usually free, sometimes continues to the apex of the curve. 
The primaries are straight, free, and reach the columella. 
This is spongy, of moderate size, and placed in line with the 
major axis of the calice. 
Some endotheca occurs between septa, chiefly near the 
margin and at the columella. 
Height, 28 mm. Diameters of calice, 14 mm. and 12 mm.
