(1). Ancylus-time. Owing to upheaval of land in the South Baltic 
region and gradually also in adjacent parts towards the north, the 
Baltic ice-sea got the character of a fresh-water lake. Climate tem- 
perate. A transgression of the Ancylus-lake takes place at a later 
phase—due to upheaval of land in the central and subsidence in the 
southern portions of the Baltic district. At that phase the lake had its 
outlet within the Danish archipelago. 
(2). Litorina-time. In consequence the Baltic by degrees came into 
open connection with the Cattegat through the Belts and the Sound and 
finally reached the salter and warmer character shown in the paper. 
Owing to a later upheaval of land—that has been greater the further 
one goes towards the central parts of Scandinavia—the saltness de- 
creased more and more and in consequence the more stenohalinic forms 
retired towards the South Baltic district, and Limneas, etc. immigr- 
ated ; the Baltic thus entering into the 
(3). Limnea-time. This time seems to come, however, so near the 
present or Mya-time that I hesitate whether it is suitable to maintain 
the Limneea-time as a particular one. (Bull. Geol. Inst. Univ. Upsala

Fossil Elephants of Tilloux.—M. Marcellin Boule calls atten- 
tion to the discovery recently made in the “ ballastiere” of Tilloux near 
the station of Gensac‘la-Pallue, of the remains of gigantic elephants, 
associated with implements of human industry. The most noteworthy 
among these fossils are two tusks of Elephas meridionalis, whose size 
surpasses all the tusks belonging to the Museum of the Acad. Sci. Paris. 
But slightly bent, their line of curvature measures 2 m., 85, while that 
of the Durfort elephant in the Museum measures 1 m., 70, and the 
modern elephant in the gallery of Zoologie 1 m., 87. M. Boule an- 
nounces also, finding in the same deposit two molar teeth belonging to 
the same individual, and the remains of other Proboscidians, such as 
Elephas antiquus and E. primigenius, also the molar teeth of Rhinoceros, 
Hippopotamus, Cervus e laphus a Bos, probably the Bison priscus 
figured in the collections of M. Chauvet. We have here then, says M. 
Boule “ a deposit similar to those of certain localities in the north of 
France, characterized by Elephas antiquus, but in which there is found 
a lingerer (E. meridionalis) and a fore-runner (the Mammoth); an- 
other proof of the continuity of geological and paleontological phenom- 
ena,” 
As to the flint fragments found in the same beds with the animals 
above mentioned, they are often very fine and reproduce the diverse
