Where the conditions are equally favourable, as in the in 
stances above mentioned, for the preservation of a 
terrestrial or freshwater fauna, many such remains will no 
doubt be detected. Thus wherever we have a preponde- 
rance of insects and land plants, we may not unreasonably 
expect to meet with land shells in greater or less abundance. 
I wish, in conclusion, to mention to this meeting the 
discovery of a new reptile in the New Red Sandstone (the 
lower Keuper), at Coten End, Warwick. Our Museum 
possesses two portions of jaws, and they are so rare that 
only six British specimens are known: two in my possession, 
two in the Warwick Museum, and the other two belonging 
to my friend, Mr. G. Lloyd, and were procured, like the 
rest, many years ago by my old friend Dr. Lloyd, and both 
of us were under the impression that they were either 
distinct from the more common Labyrinthodont remains, 
or at any rate would form a new species. After a careful 
study, Professor Huxley has come to the conclusion that 
they are quite distinct, and he has given them the name of 
Hyperodapedon, and just at the present time they are of 
special interest and value, since their occurrence in the 
New Red Sandstone of this county, helps to determine the 
age of certain disputed sandstones at Elgin in Scotland, 
which contain remains of the same reptile, and which had 
been supposed to belong to the Old Red Sandstone, but 
must now be placed higher up in the Trias. They also 
fix the Geological horizon of certain Indian and African 
rocks, which yield the Hyperodapedon still more fre- 
quently. The British fossils consist of portions of jaws 
with teeth, which are remarkable for possessing a double 
row of teeth, in parallel rows, close together, and the 
other anotomical peculiarities will be pointed out by
