and Raymond Terrace, New South Wales, and Dana, at Glendon, New 
South Wales. Mr. Etheridge found it at Gympie and Smithfield Reef, in 
Queensland. The Rev. W. B. Clarke found it at Glen William, on the Williams 
River, in a brownish, compact, brittle limestone, in which it accompanies 
F, Morrisii^ McCoy, and Q-riffithides Mchwaldi, Eisher.

fig. 2 (fig. 1 excL). 
The coenoecium of this species, which seems not to be of very great 
size, is shaped like a funnel, very shallow at its upper part, and with walls 
more or less irregularly folded or waved. The branches are filiform, regular, 
sub-parallel, and bifurcated towards the top ; the cross-bars have the same 
thickness as the branches ; they are sub-equidistant, and give rise to oval 
fenestrules, the greater diameter of which is from two and a half to three 
times the length of the smaller. There are seven cells for each fenestrule, 
and the two rows are separated by a faintly-indicated mesial keel. I could 
find no trace of strise or other ornamentation on the exterior surface of this 
Bryozoa ; it appears to be completely smooth. 
Dimensions. — The specimen sent me is from four to five centimetres 
long ; its diameter at the upper edge is from three to five centimetres ; but it 
far from complete. The fenestrules are two millimetres long and about three- 
quarters of a millimetre broad. 
Delations and Differences. — This species closely resembles F. multi- 
porata, McCoy, by the form and arrangement of its branches ; it is easily 
distinguished from it by the oval form and slight irregularity of its fenestrulesj 
which are rectangular and very irregular in its congener, the inner surface 
of which also is regularly striated. It seems to me to be identical with 
that which J. D. Dana has identified with Frotoretepora {Fenestella) ampla, 
Lonsdale, though probably it should be constituted a new species. 
Horizon and Localities. — This species accompanies the preceding in 
the limestone at Glen William. Dana found it at Glendon.
