P. 4501a. Small imperfect tooth, deeply notched posteriorly ; Plio- 
cene, Antibes, S. France. 
Presented hy Miss Battersby, 1883. 
The following extinct species has also been determined upon the 
evidence of detached teeth, hut there are no examples in the Collec- 
tion : — 
Carcharias (Seoliodon') kraussi, J. Probst, Wiirtt. Jahresh. 
vol. xxxiv. (1878), p. 120, jil. i. figs. 7-11. — Molasse; 
Baltringen, W'iirtemberg. 
A tooth of an undetermined species, from the Miocene of Naples, 
is also figured by 0. G. Costa, Paleont. Eegno Napoli, pt.ii.(1864— 56), 
pi. vii. fig. 62 (Corcu; appendiculatus). 
Some small teeth from the Pluncrkalk of Bohemia originally de- 
scribed under the name of Oxyrhina lietei-omorphn by A. E. Eeuss 
(Verstein. biihm. Kreideform. pt. i. 1845, p. 7, pi. iii. figs. 14-16) 
were subsequently assigned by the same author {op. cit. pt. ii. 1846, 
p. 100, pi. xxiv. figs. 23, 24, pi. xlii. figs. 10-12) to Scoliodon, with 
the name of S. prigeus. By later authors, however, these teeth are 
ascribed to Oxyrhina anyustidens, Eeuss (see p. 380). 
Vertebrm from the Molasse of Switzerland and Wiirtemberg are 
also described as referable to this subgenus by C. Hasse, Natiirl. 
Syst. Elasmobr., Besond. Theil, p. 270, pi. xxxix. fig. 5. 
A shark from the Upper Eocene of Monte Bolca, near Verona, 
having a dentition very suggestive of that of Scoiiodon^ is made the 
type of a distinct genus, Protoyalevs, E. Molin (Sitzungsb. math.- 
nat. Cl. k. Akad. Miss. Wien, vol. xl. 1860, p. 585), subsequently 
named Alopiopsis P. Lioy (Atti Soc. Ital. 8ci. Nat. vol. viii. 1865, 
p. 403). The type species is the following : — 
Protoyaleus cuvieri, E. MoUn, tom. cit. p. o83 : S<piahts carcharias, 
Volta {non Eisso), Ittiolit. Veron. (1796), pi. iii. fig. 1 :
