papers 1 ; the corresponding fossils of France are noticed by P. Ger- 
vais (op. cit .) and H. E. Sauvage 2 ; of Switzerland by F. J. Pictet 
and G. Campiche 3 ; of Saxony and Bohemia by A. E. Beuss 4 , H. B. 
Geinitz 5 , and A. Fritsch 6 ; of Bussia by Y. Kiprijanoff 7 ; of India 
by Egerton 8 and Stoliczka 9 ; and of the United States by E. D. 
Cope 10 and J. Leidy u . A few important skeletons are known from 
the Senonian Beds of Westphalia 12 ; and the uppermost Cretaceous 
deposits of Mount Lebanon have furnished numerous well-preserved 
fishes, first noticed in detail by J. W. Davis 13 , but considerably 
revised in the present volume. 
The innumerable Selachian teeth of Tertiary age, discovered in 
almost all marine deposits, are described in several extensive 
memoirs. In England, many are noticed by F. Dixon (op. cit.) ; 
those of France are made known by P. Gervais 14 , F. Bassani 15 , and
