GANOIDS. 
Ctenodus ellipticus. Hancock and Athey. 
Very rare. Two or three teeth. A few head bones and 
ribs are all I have seen. 
C. TUBERCULATUs. Hancock and Athey. 
A single tooth, ribs, and dermal headplates. 
HoLOPTTCHius SAUROIDES. Agassiz. 
Strepsodus SAUROIDES. Huxley. 
Scales of the former and teeth of the latter are found in 
tolerable abundance. They are usually found detached. 
Megalichthys Hibberti. Agass. 
The remains of this fish are tolerably abundant. They 
vary extremely in size. The scales are occasionally found 
connected, oftener detached ; teeth, vertebrae, and head bones 
are common. 
A large, nearly complete specimen, measures two feet six 
inches without the head, which is unfortunately wanting.

fully preserved.
