Genus EOTHYNNUS, novum. 
8yn. Ccelocephalus, L. Agassiz, Poiss. Foss. vol. v. pt. ii. 1844, p. 139 
(name only) \ 
A genus known only by the head, which is essentially identical 
with that of Thynnus, but seems to be deeper in proportion to its 
width. Teeth on margin of jaws very small and clustered in more 
than one series. 
Eothynnus salmoneuSj sp. nov. 
1844-44. Caslocephalus salmoneus, L. Agassiz, Poiss. Foss. vol. v. pt. ii.

Type. Imperfect cranium ; British Museum. 
The type species, with head and opercular apparatus sometimes 
nearly 0-25 in length. Width of cranium at occiput about two 
thirds maximum depth of head. Maximum depth of operculum 
a hout twice its greatest width. 
Form. 4 - Loc. Lower Eocene (London Clay): London Basin. 
P- 623. Very imperfect cranium, labelled by Egerton as intended to be 
the type specimen of this species ; Sheppey. Egerton Coll.
