The Gosau Beds in the Austrian Salzkammergut.— The 
extensive literature of the Gosau Beds is a proof of their importance 
from a geological point of view. Since 1832 this remarkable forma- 
tion with its unique fauna has been under discussion among European 
geologists. In a paper published in the Quart. Journ. Geol. Soc., 
1894, Mr. H. Kynaston brings together the results of previous investi- 
gation on the stratigraphy and paleontology of the Gosau Beds, and 
gives an account of his own observations made with referenceto fixing 
their geological horizon. The beds are divided into an upper and 
lower group, the latter extremely fossiliferous, while the former is 
almost devoid of organic remains. On both stratigraphical and pale- 
ontological evidence, the author correlates the Lower Gosau Beds with 
the Turonian amd Senonian of the south of France. These in turn 
represent the English Middle and Upper Chalks. The Upper Gosau 
Beds being non-fossiliferous, cannot be located definitely, but the prob- 
ability is that they represent the Danian of other districts and are on 
the same horizon as the chalk of Maastricht and Aix-la-Chapelle. 
Geology of the Rocky Mountains between the Saskatche- 
wan and Athabasca Rivers.—During the summers of 1892 and 
1893, some explorations were made in the Rockies between Howse 
Pass and the Athabasca Pass. This tract of mountains, including 
some of the grandest mountain scenery in North America, has been 
neglected by scientific observers, so that, maps hitherto published repre- 
sent it incorrectly. New lakes and rivers were discovered, heights of 
peaks determined, and paleontological collections made. The results 
of a geological reconnaisance of this region are summarized as follows 
by Professor A. P. Coleman: 
“To sum up the geological features of the region examined, we may 
describe the southeastern portion, well displayed along the Brazean 
River, as consisting of a series of seven or more minor ranges, each 
striking northwest and southeast, and tilted 25°-45° toward the coast 
line of the Pacific. These blocks, consisting of thousands of feet of 
quartzite and conglomerate, often overlain by thousands of feet of 
Devonian limestones, appear to have been thrown into their present 
attitudes by a series of reversed faults, as described by McConnell in 
Bow Pass. The rare folds observed in this portion of the mountains 
represent, perhaps, the dying out of such faults. Though no Creta- 
ceous rocks have been proved to overlie the Devonian strata, it is 
probable that the faulting which produced the mountains took place
