come to all who take an interest in Tertiary Geology. Accordingly 
we are very glad to see published the results of Professor Reuss’s 
examination of the German Upper Oligocene Foraminifera, Bryozoa, 
and Corals, which have appeared in the ‘ Sitzungsberichte’ of the 
Vienna Academy (vol. i.). 
Of Foraminifera the beds are known to contain 142 species, of 
which 67 (47 per cent.) are peculiar to that horizon, 47 (83 per 
cent.) occur in Middle Oligocene strata, 42 (29°5 per cent.) in 
Miocene deposits, 23 (16 per cent.) in Phocene beds, and 16 
(11:2 per cent.) occur at the present day. The proportion of 
species common to the Upper Oligocene and to the Middle does 
not differ, therefore, very materially from that common to the 
former deposit and the Miocene. 
Of the Corals not much can be said ; only seven species that can 
be determined with safety are known to Professor Reuss, of which 
one occurs also in the Crag of Suffolk and Antwerp, and one in the 
Lower Oligocene beds of Latdorf, while the remaining five are 
peculiar to the Upper Oligocene. 
The Bryozoa are, however, much more numerous, 74 species 
having been determined by the author; of these, 14 species are 
found in the Lower, and 21 in the Middle Oligocene, 18 being also 
known in Miocene deposits. It will thus be seen that this evidence 
tends to the same conclusion as that of the Foraminifera. 
The Middle Oligocene fauna does not possess the same interest 
as the Upper in a classificatory point of view, but Professor Reuss’s 
more recent researches on its Foraminifera, Corals, and Bryozoa 
have an equal intrinsic value to the pure paleontologist. 
In the ‘Annals and Magazine of Natural History’ for Sep- 
tember, Dr. Duncan described six new species of Corals from the 
South Australian Tertiary strata. They include one new genus 
(Conosmilia), which presents certain novel structural peculiarities, 
and which bridges over the gaps between some of the families in 
the accepted classification. It ‘‘ possesses the twisted ribbon-shaped 
columella of the sub-family Caryophyllacexw, the endotheca and 
septal margin of the Trochosmiliacex, and the irregular septal 
arrangement which was so common in the Corals of the Oolitic age, 
and which, from its octomeral type, reflected the Rugosa of Paleo- 
zoic times.” In this coral, therefore, we have again a trace of that 
Jurassic facies so characteristic of the recent Australian land-fauna. 
Another curious feature is seen in the only known species of this 
genus, namely, that the bases of the septa and the cost are not 
continuous, but the septa appear to correspond with the line of 
depression between the cost; but what is more remarkable still is 
that, according to Dr. Duncan, this feature “is common in species 
of other genera in Australia, but is very rare indeed in any speci- 
mens from any other part of the world.” (The perusal of papers
