pensation will be made if we should in return confer upon it 
a portion, however small, of the more naked dignity of de- 
monstrative truth.

LXVIII. Catalogue of Fossil Fish in the Collections of Lord 
Cole and Sir Philip Grey Egerton, arranged alphabetically ; 
with References to the Localities, Geological Positions, and 
| published Descriptions of the Species. By Sir Puivip DE 
Matpas Grey Ecerton, M.P., F.R.S., £.G.S. 
To the Editors of the Philosophical Maguzine and Journal. 
GENTLEMEN, 
Be following “ Catalogue of Fossil Fish” was printed for 
private distribution, but I am induced tosolicit its insertion 
in your widely-circulated Journal in the hopes that it may 
prove of interest beyond the immediate pale of my personal 
friends and acquaintance ;—to the geological adept, as exhi- 
biting in a tabular form the stratigraphical position of two 
hundred and twenty-seven species,—to the student in fossil 
ichthyology, as affording a clue to the depositories of many 
new and rare specimens destined to appear in the forth- 
coming numbers of Dr. Agassiz’s ‘ Recherches sur les Poissons 
Fossiles.” 
To the discriminating eye and classic orthography of that 
distinguished naturalist I am indebted for the diagnosis and 
nomenclature of the new genera and species enumerated in the 
Catalogue, as well as for the identification of such as were 
raleady known. I remain, Gentlemen, yours, &c.
