probably more genial ; for amongst the companions of the sea-snake of 

 Bracklesham was an extinct Gavial [Gavialis Dixoni, Owen), and numer- 

 ous fish, such as now frequent the seas of warm latitudes, as the sword-fish 

 (see fig. 208), and gigantic rays of the genus Myliobaies (see fig. 209).

The teeth of sharks also, of the genera Carcharodon, Otodus, Lamna, 

 Galeocerdo, and others, are abundant. (See figs. 211, 212, 213, 214.)

The Nummulites IcEvigata (see fig. 210), so characteristic of the lower 

 beds of the calcaire grossier in France, where it sometimes forms stony 

 layers, as near Compiegne, is very common at Bracklesham, together with 

 iY. scahra and N. variolaria. Out of 193 species of testacea procured 

 from the Bagshot and Bracklesham beds in England, 126 occur in the 

 ealcaii-e grossier in France. It was clearly therefore coeval with that 

 part of the Parisian series more nearly than with any other.
