NEUMAYR—CEPHALOPODA OF BALIN. 9 
The Black Sea, the Mediterranean, and White Sea exhibit, on the 
contrary, lithological characters entirely different ; since mud or silt 
predominates, and the sandy deposits are there reduced to a small 
extent. [J. P.] 
On Fossit TrpHacem. By Prof. F. Unerr. 
[Proc. Imp. Acad. Vienna, January 7, 1870.] 
THE existence of representatives of the genera Typha and Spar- 
ganium in Tertiary deposits has been but lately ascertained, and 
many remains of the former genus are probably still regarded as 
species of Arundo. <A species of Typha, first discovered by M. D. 
Stur, is widely diffused. Certain vegetable forms found in the 
Gosau Sandstones of Gams, in Styria, possibly represent the proto- 
type of all the Typhe of subsequent periods. At present three 
species of Typha and six of Sparganium are known to exist in a 
fossil state. [Count M.] 
On Devonian Entomosrraca. By M. P. Ricurer. 
[Zeitschr. deutsch. geol. Gesellsch. 1869, p. 75.] 
M. Ricuter has described the Entomostraca contained in the De- 
vonian strata of Thuringia. The uppermost horizon, in which fossil 
Entomostraca are very abundant, is perfectly analogous to the Cy- 
pridina-shales of the Harz and of Nassau. In the second horizon 
they are far less abundant, and in the lowest no trace of them has 
been detected. ‘The author describes and figures eleven species of 
Cypridina (six new), three of Beyrichia (all new), and two of Cythe- 
rina (one new). He regards the oval individuals of Cypridina as 
males, and the more spherical forms as females. [Count M.] 
On the Cernatopopa from the OoxitE of Battin, near Cracovia. 
By Dr. M. Neumayr. 
[Proc. Imp. Geol. Inst. Vienna, December 21, 1869.] 
Dr. Neumayr publishes a list of the Cephalopoda from the Oolitic 
beds of Balin, from which it appears that the Macrocephalus- and 
Aspidioides-zones are best represented, and next to these the Anceps- 
and Athleta-zones, so that the Cephalopodous fauna of Balin may 
be regarded as corresponding to those of the Great Oolite above the 
Fuller’s Earth in England, of the “‘ Callovien” in France, and of the 
upper horizon of the Dentalium- and Ornatus-clays, and of the Ma- 
crocephalus-oolite of Wiirtemberg. <Amaltheus (Amm.) Lamberti, 
which constantly occurs above the Ornatus-clay, has not yet been 
found, nor have any traces of species of more recent date. The only 
representative of a deeper horizon is a fragment of an Ammonite, 
very nearly allied to but not identical with Stephanoceras bifur- 
catum, Ziet., of the Parkinsoni-zone. ‘This fragment may prove, on 
closer examination, to be an inner whorl of a species belonging to 
the group of Cosmoceras calloviense, C. Gowerianum, &c., which, in
