remaining very narrow ; the calices are usually single, alternately springing 
from the stolon-like corallites right and left, oceasionally, however, two issue 
from the same corallite, more or less opposite one another. Tahulae absent. 
Sejita, as very fine and numerous stria3, extending the whole depth of the calices. 
Obs. — Prof. Pe Koninck has very aptly expressed the form of this 
peculiar coral hy comparing the separated corallites to an ordinary clay-pipe. 
As a rule, the calices sj)ring from the stolon-like corallites singly, but at 
times two appear to issue from the same pedicle. 
The tissue composing the corallites is very dense, and apparently 
fibrous, the connecting passages very narrow, and no evidence of tabulae has 
been observed. With the exception of a very small portion of surface of one 
of the calices, the tissue appears to be perfectly homogeneous, but at this point 
a vermicular structure is apparent. I regret that the material at my disposal 
is too limited in quantity to warrant the preparation of microscopic slides, 
and I am, in consequence, unable to institute a comparison with the structure 
of the genus 3Ionilopora, N. & Eh Should further research establish the 
presence of a reticulate strueturc in the Australian coral it will necessitate a 
re-examination of Monilopora. 
Localitif- and Horizon. — Three-quarters of a mile north-west of Fallal 
Station, Horton lliver, Co. Murchison {C. Cullen) : — horizon doubtful, but 
probably Carboniferous. Hungog Road, nineteen miles from West Maitland, 
Co. Durham, [Messrs. J. IFaterhouse, M.A.; T. IF. E. Eavkl. E.A., and II. 
Etheridge^ Junr. ; and C. Cullen.) : — Mirari Limestone, Carboniferous. 
Order ?— MONTICULIPORIDEA.^^ 
Family— MONTICELIE OFIEJE. 
Sub-Family — Stenoporinoe.'* * 
Obs. — The family Monticuliporidai has been subdivided by Messrs. 
Waagen and Wentzel into three sub-families, of which the Stenoporinse forms 
the third, and is certainly a most convenient section. They place in it two 
genera — Stenopora, Lonsdale, and Geinitzella, W. & W. To these I would 
add Tabtdipora, Young, for reasons to be explained later.
