Zaphrentis, indicating the great group of the Rugosa. At a few localities 
they have been met with, not in speeifie ahundanee, but in a plenitude of 
individuals. Equally does this statement hold good for the Permo-Carbon- 
iferous of Queensland, and I believe for Tasmania also. So little is, however, 
knoAvn of the fossiliferous contents of the thick limestones of Western 
Australia that such a generalisation cannot he applied to that Province at 
present. 
A glance at the results attained by the four principal Avorkers in the 
Palrcozoic PalaAontology of Eastern Australia, during the forty-five years 
AAdiich have elapsed since Lonsdale AAU’ote, Avill impress this question strongly 
on the mind of the reader. Lonsdale,^ in 1844* *, described the new genus 
Stenopora and four sj)ecies from Ncav South Wales and Tasmania, aftei’AA’ards 
recapitulating these, and adding a rugose coral, Amplexus arundlnaceus? 
The last named and tAvo of the foregoing species of Stenopora were quoted 
l)y M'Coy^ in 1847, and three other corals added, one being a new genus and 
species, Cladochonus tenuicolUs. Passing on to the researches of Lana, we 
lind that he merely localised Lonsdale’s Stenoporee and added a fifth species, 
hut under the name of Chcetetes graciUs^ Lastly Ave come to the work of 
the late ITof. L. G. dc Koninck, by Avhom the collections of the late Rev. W. 
P. Clarke Avere classified and described. Le Koninck,® as aatII as revicAAung 
many of those already referred to, added thirteen species to the Australian 
Permo-Carboniferous Coral Eaima, appertaining to scA^en genera, not pre- 
viously described as coming from that horizon. Omitting one of Le Koninck’s 
species {Lithostrotion hasaltiforme) from the Murrumhidgee,*’ the total gives 
us nine genera and tAventy-one species recorded during the long period in 
(piestion, hut the species may he reduced to tAA'euty by the elimination of one 
of Prof. M'Coy’s, viz., Tiirhinolopsis hina, probably determined on the internal 
cast of a Zaphrentoid coral. Of the genera, two Avere specially established 
for the reception of their species.

' There are no Permo-Carboniferous rocks on this river. The cor.al in question occurs in the Cave Lime- 
stone, at Cave Flat, on tlie Murrumbidgee, south-west of Downing, and it is questionable if it be a Lithostrotion 
at all. Tlie Cave Limestone is either Upper Silurian or Siluro-Devonian.
