Remains of the Elasmotherium. — M. de Keyserling has dis- 
covered at Surico (on the borders of the Caspian sea) a tooth of 
the Elasmotherium ; an animal which appears to have been one 
of the class pachydermata, and more nearly resembling the ele- 
phant than any other animal ; but as this tooth indicates some 
relation between the Elasmotherium and the Rhinoceros, M. de 
Keyserling concludes, that it served as a connection between the 
rhinoceros and the elephant. M. Fisher has compared it with 
the structure of that of the Elasmotherium Sibiricum (discovered 
in 1808), and finds it quite distinct; hence he has named the 
species E. Keyserlingii, and is therefore the second of the genus.
