Type. Nearly complete fish ; Paris Museum of Natural H‘story. 
The type species of the so-called genus Notceus , attaining a length 
of about 0'25. Length of head with opercular apparatus much 
greater than the distance between the paired fins, about equal to 
the maximum depth of the trunk, and contained somewhat more 
than four times in the total length of the fish. Libs longer than 
the neural arches. Dorsal fin-rays not less than 40 in number. 
Form. Sf Loc. Upper Eocene (Gypsum): Montmartre, Paris. 
Not represented in the Collection. 
The following specimens represent an undetermined species as 
large as A. valenciennesi , differing from this apparently in the more 
slender proportions of the trunk :— 
44098, Fish in side view wanting the caudal fin, preserved in the 
two halves of a much-pyritized nodule ; supposed to have 
been obtained from the Miocene of France. 
Far chased, 1873. 
44638. Anterior half of fish, vertically crushed, in a similar nodule, 
much pyritized; entered in the Register as from “ Au¬ 
vergne.” Presented by Henry Ludiam , Esq., 1873. 
The following vertebrae of Amia are also not specifically de¬ 
termined :— 
P. 6477. Two large vertebral centra, probably from the Upper 
Eocene of the Hampshire Basin. Beckles Coll. 
P.1532 x. Another large vertebral centrum, much broader than 
deep ; Upper Eocene, Hordwell, Hampshire. Egerton Coll. 
P. 1532 y, z. Smaller centra ; Hordwell. Egerton Coll. 
The imperfect fish described as follows, exhibits no characters- 
by which it can be distinguished from Amia : —
