Records appearances in dentine suggestive of its formation by a con- 
nective tissue calcification, thus indicating that the process is more like 
the formation of bone than hitherto supposed. Illustrations are adduced 
from several Mammals.

Describes and figures remaius of Cyon, Sheep, Saiga, Ibex, and 
Chamois from the Pleistocene of Moravia. The sheep is referred to a 
new species allied to the Argalis ; while the Saiga is likewise new, beings 
distinguished from the existing species by its superior size, and the 
presence of three lower premolars. At the end of the paper some obser- 
vations are added on Ovis antiqua and Caprovu savigni. It is considered 
that the presence of fossil remains of Chamois and Ibex in the plains of 
Europe indicates that these animals were driven from the mountains by 
cold. [See Canidce aud Bovidce.]
