Review of Recent Geological Literature. 71 
followed by a very complete series of lower and middle Silurian beds, 
which, the author concludes, is nearer in its stratigraphical relations to 
the succession on the east coast of the Baltic than to that of Sweden 
(Gland and Dalarne). 
Ueber Hypostomen von Homalonoien. By L. Beushausen. (Jahrb. 
Konigl. preuss. geolog. Landesanst. f. 1891, pp. 154-166, 1892.) 
From the examination of the hypostomes of a few species represent- 
ing some of the subgenera of Homalonotus, the author concludes that 
these plates do not show differentials of taxonomic value. 
Sobreel Terreno Jurdsido y Cretdceo en h>s Andes Argentines cut re 
el Rio Diamante y Rio Limay. By William Bodensender. (Boletin 
Acad. Nac. de Ciencias de Cordoba, vol. xm, pp. 5-17, 1892.) 
A narrative of important geological investigations conducted by the 
author, with lists of fossils identified by Behrendsen in Zeitschr. deutsch. 
geol. Gesellsch., 1891-2. 
Die Gebirgsformen in siidwestlichen Kdmten, and Hire Entstehung- 
By Fritz Frech. (Zeitschr. der Gesellsch. fur Erdkunde zu Berlin, 
vol. xxvn, pp. 349-390, 1892.) 
A very instructive chapter on orogeny and geotectonics. The author 
discusses first the origin of the principal valleys, and secondly their mod- 
ifications during the glacial and recent epochs. Under the latter heads 
are discussions of the extent of glaciation, and morainic distribution; 
of old and late glacial deposits; of the "Kare" and their origin ("under 
the term 'Kare' are included the cauldron-shaped niches below the 
mountain crest, which, behind and at the sides, are enclosed by steep 
walls, while the flat floor of the basin is open only at the front and 
there passes directly into a steep decline. In the summit Alps most of 
the 'Kare' are now filled with glacial ice and appear to be the birth 
places of the great glaciers"); of lakes due to glacial rotation and corro- 
sion, and morainic damming; postglacial erosion and vale-making ; ca- 
tastrophic modifications, etc. 
Das Rheinthal von Bingerbrilck bei Lahnsteiti. By E. Holzapfel. 
(Abhandl. Konigl. preuss. geolog. Landesanst. Neue Folge, Heft 15, pp. 
1-116, 16 plates, photogravures and haif-tones, 1 map, 1893.) 
Gives a detailed account of the geological structure of this classical 
region, with an especially important chapter on the classification of the 
Rhenish lower Devonian. 
Die Jurabildungen des Kahlberges bei Echie. By James Pebrin 
Smith. (Inaugural Dissertation, 1893, pp. 1-72, 2 pi., 1 map.) 
The Kahlberg is in north Germany, between Einbeck and the Hart/, 
mountains. The author describes the geological succession of this region 
with some detail, giving special attention to the upper or white Jura, 
with comprehensive sections and lists of fossils. The palseontological 
part of the work includes descriptions of many new forms and concludes 
with a tabulated list of the fauna.
