Vertebrae of Oxy rhino are also described by C. Hasse, TSatiiil. 8} st..^ 
Elasmobr., Besond. Theil (1882), from the Chalk of Orel, Russia (op. 
cit. p. 234, pi. xxxi. fig. 47), and from the Tertiaries of Baltringen, 
Flonheim, and Antwerp (op. cit. p. 234, pi. xxxi. figs. 43-46).

The so-called Oxyrhina arnaudi , H. Coquand (Descript. Geol. etc. 
Depart. Charente, vol. ii. 1860, p. 133), from the Santonian Beds of 
France, is considered by H. E. Sauvage to be probably founded upon 
a tooth of Corax (Bull. Soc. Geol. France, [3] vol. viii. 1880, 
p. 456). 
Genus LAMNA, Cuvier.

Syn. Otodus, L. Agassiz, Poiss. Foss. vol. iii. 1843, p. 266. 
Second dorsal fin and the anal very small. A pit at the root of 
the caudal fin, which has the lower lobe much developed; side 
of the tail with a keel. Dentition only differing from that of 
Oclontcispis (p. 360) in the relatively less elevated and less subulate 
character of the anterior teeth, and the usually larger size of the 
lateral denticles. 
By Oxy rhino manteUi this genus appears to be connected with 
Oxyrhina ; by Lamna obit qua with Carchorodon. 
1 Some doubtful Tertiary teeth are also assigned to this species by O. G. 
Costa, Pale out. Regno Eapoli, pt. i. (1850), p. 121, pi. ix. figs. 8,19.
