In the south of France the older fauna occurs and affords the best 
means of determining the exact stratigraphic position of the beds in 
which the fossils are found. 
In la Bresse the older fauna is found in the lacustrine deposits of the 
lower Pliocene and in the fluviatile beds of the middle Pliocene; the 
recent fauna is finely developed in the sands of Chagny. 
In England the Hipparion fauna is found in the nodule-beds at the 
base of the red Crag and in the red Crag itself, while the Equus fauna 
is contained in the fluvio-marine Crag. 
A comparison of stratigraphic details shows that the older Pliocene 
fauna is lacking in the Central Plateau region of France, and the hor- 
izon of Perrier with the Mastodon bearing sands of Puy, of Coupet 
and of Vialette must be placed in the upper Pliocene not withstan 
ing the total absence of Elephas meridionalis. 
The fauna of Sainzelles presents the same characters as that of Per- 
rier and can be considered only as a simple local sub-division of the 
same bed. 
From these’ facts M. Deperet also concludes that the basalts inter- 
calated in the gravels of Perrier and the Mastodon-bearing sands of 
Puy, and the breccias which accompany them, belong to the upper Ph- 
ocene, and, chronologically, are very near to the basalts of the Plateau.

Plistocene Diastrophism in the California Coast.—Mr. À. 
C. Lawson has obtained data which establishes (1) The uplift from the 
sea of the entire coast of California from San Francisco to San Diego, 
in Plistocene time, from 800 to 1500 feet. (2) A differential move 
ment of the crust, to a remarkable degree, in the vicinity of Cat 
Island, and near the city of San Francisco, also of Plistocene agè. 
The uplift changed the contour of the coast, which at the close 
the Plistocene had had the aspect of an archipelago and was well pop 
plied with harbors. The Channel Islands are remnant of the Phiocen? 
condition, but the harbors have disappeared with one exception. 
The orogenic movement resulted in the lifting 0 
into its present condition and the upthrust of the 
which is described as having a central granite mass from via 
strata of all ages dip quaquaversally. The mass antedates 5 ae 
est sedimentary strata on its flanks. In his conclusions vet a 
states that the subdivisions Eocene and Neocene are not su? sian

from a process of depression to that of uplift is believed to ©
