Sp. Char. Polyzoarium infundibuliform, regular in appearance. Interstices 
narrow, straight, tnedianly keeled and sometimes tuberculate, andfrequently dichotomis- 
ing; dissepiments short, of less breadth than the interstices. Fenestrules oval. Cells 
round, three to a fenestrule, two being situated on each margin, and one opposite the 
dissepiments on each side. Reverse granular-striate. 
Obs. F. internata appears to differ from F. fossula only in being of a larger 
habit, and although a regular closely knit species it does possess the same densely 
retiform appearance. In the case of this species, Lonsdale again distinctly says tha 
the celluliferous face is internal. The examples from Queensland, like the type, are 
casts only, or rather impressions left by the removal or decay of the polyzoarium. In 
such instances it is exceedingly dilfieult, even with the aid of squeezes in relief, taken 
from them, to express with accuracy the characters of the fossil under description. 
When only two rows of zoecia exist on the branches of this species, the dividing keel w 
straight and sharp ; but when the latter is augmented they become less defined and 
wavy. This is equally visible in Tasmanian specimens.

Obs. This form boars a resemblance to Lonsdale’s F. internata, but it 
apparently too large in habit, and the number of cells in a given space is too great,

from four to six within theTength of a fenestrule ; the latter appear to have been oval. 
In places a third row of cells is developed, especially previous to the bifurcation of tie 
interstices. Only one specimen has been examined. ^
