P. 270. The tooth figured in Quenstedt’s 4 Jura ’ under the name of 
Hybodus grossiconus received the subspecific name of

1860, p. 695).

Among non-Elasmobranch fossils erroneously determined, and 
not already mentioned in the text, may be placed the following:— 
Pristis dubius, G. von Munster, Beitr. Petrefakt. vii. (1S46), 
p. 47.—Corallian; Hanover. [Probably a fin-ray of a 
Tepidotoid Ganoid.] 
Hemicladodus unicuspidatus, J. W. Davis, Quart. Journ. Geol. Soc. 
vol. xl. (1884), p. 620, pi. xxvii. fig. 24.—Yoredale Bocks ; 
Wensleydale, Yorkshire. [Fragment of splenial dentition 
of Amphicentrum or CheirodusJ] 
In the earlier pages the Upper Cretaceous of Mount Lebanon, 
yielding fossil fishes, is identified with the Turonian (after Oscar 
Eraas and J. AY. Davis); in the later pages the formation is 
assigned to the Senonian (after E. Aoetling and W. Dames), the 
character of the fish-fauna being more in accordance with the latter 
determination.
