Of the preceding twenty-four species, the greater part are Physostom- 
ous Actinoptert, and there is no species of a Physoclystous family in the 
list.* No trace of spines or scales of fishes of the latter character have 
been yet discovered in strata of this pefiod in the West, though one 
(Beryzx insculptus, Cope,) has been discovered by Dr. Lockwood in the 
green-sand marl of New Jersey. 
In the second place, it is of importance to observe that the genera have 
nearly all been obtained from the chalk of Europe. Porthews is repre- 
sented perhaps by some specimens referred to Hypsodon ; one species of 
Ichthyodeetes is figured by Dixon from Sussex, and one of Cimolichthys 
and Pachyrhizodus each. Hnchodus has long been known from Holland, 
ete., Apsopelix, Hmpo and Stratodus being so far the only ones not found 
in Europe. This is of much interest in every respect, and points to the 
synchronism as generally understood, between the chalk formations of 
Kansas and of England.

*In describing Hlasmosaurus I state that remains of six species of Physoclystous fishes were 
found in the matrix surrounding the bones. This statement was founded on the assumption of 
previous authors, that the forms of fishes above described were related to Sphyraena.
