border of the steppe there are two protrusions of limestone, with 
Terebratula elongata, Loxonema, &c., on outcrops running nearly 
N.W. and 8.E., which throw off the cupriferous sands east and west. 
The western of these outcrops in its southern continuation near 
Sakmarsk is charged with Permian fossils, including the above. The 
same limestone, regarded by the author as belonging to the Zechstein, 
crops up in other places, and apparently underlies the whole basin of 
the steppe, the upper sandstones resting conformably uponit. From 
the latter the author gave the following list of fossils :—Cardto- 
pteris Kutorge (=Aroides crassispatha), Walchia biarmica and 
piniformis, Lepidodendron, Schizodendron tuberculatum, Anomorrhea 
Fischeri, Caulopteris 2; Calanites infractus, Suckowt, gigas, and 
lecoderma ; Unio umbonatus, Platyops Richardi (a Labyrinthodont), 
Lthopalodon Wangenhiuseri, Cliorhizodon orenburgensis, Deutero- 
saurus, and various Labyrinthodont and Reptilian remains. Upon 
these the author remarked that the list of plants has a Paleozoic 
aspect, while the Reptilian remains seem to be more of a Secondary 
character. After consideration of all the facts, the author came 
to the conclusion that possibly some of the beds in the central part ~ 
of what is known as the Permian basin may be passage-beds be- 
tween the Permian and Trias, but that the Kargalinsk series includes 
the uppermost beds of the Permian. 
4. “On Chilostomatous Bryozoa from Bairnsdale (Gippsland).” 
By A. W. Waters, Esq., F.G.S. 
This paper continues the author’s papers on South-Australian 
Bryozoa, already communicated to the Society. It describes a collec- 
tion made by Mr. J. R. Y. Goldstein, containing 40 forms, of which 12 
were not previously known to have existed in Australia. Several 
species, however, known in other places as incrusting, here occur in the 
Eschara habit ; and all together the number of incrusting species from 
this locality is small. The author calls attention to the frequency 
with which the Australian Bryozoa exhibit different modes of growth, 
showing the importance of preferring for classification zocecial to 
zoarial characters. ‘The three localities in Australia have furnished 
126 species of Chilostomata, of which 51 are known living and 41 
fossil; 14 are considered identical with European Miocene species, 
17 with Pliocene, and 4 are thought to be identical with Cretaceous 
species. The author gives a detailed description of the various 
_ species in his Bairnsdale collection. 
5. “The Silurian Species of Glauconome, and a suggested Classi- 
fication of the Palzozoic Polyzoa.” By G. W. Shrubsole, Esq. 
F.G.S., and G. R. Vine, Esq. 2 
The authors discussed the history of our knowledge of the gents 
Glauconome, and especially of the Silurian species. They then 
characterized the genus, to which they refer only the Bala species 
formerly regarded as identical with G. disticha, Goldf., but which 
they describe as G, Sedgwicku, Shrubs. Glauwconome disticha, Goldf.,
