ocene e by the sr reseeen megarhinus, and to the late Pleistocene 
by the Ovibos moschatus. The presence of een sins dus latidens 
in Kent’s Hole, and of the 2h. megarhinus in the cave of Oreston, 
tends to the conclusion that some of the caves in the pe: of Eng- 
land contain a fauna that was living before the late Pleistocene 
age. The whole assemblage of middle Pleistocene animals evinces 
a less severe climate than in the late Pleistocene times.

Pleistocene is represented by a river-deposit in Auvergne, and by 
a cave in the Jura, in which the presence of the Mickie lati- 
dens, and a non-tichorine rhinoceros, and the absence of the char- 
lar animals of the early Forest-bed stage, ’ prove that that era 
must be Middle Pleistenans, The Early Pleistocene division is 
represented in France by the river-deposit at Chartres, being char- 
acterized by the presence of two non-Pliocene animals, Zrogonthe- 
rium and Cervus varnutorum.
