man hands. The circumstance having been made known to the 
Natural History Society of Liverpool, a committee was appointed, 
which drew up the report under consideration, The red sandstone 
of the peninsula in which the Storeton quarries are situated, may be 
separated into three principal divisions, the medial of which is 
worked at Storeton, where the strata of marl and sandstone are of 
unequal thickness, and are separated by their seams of whitish clay. 
It was on this clay that the Cheirotherium and other animals had 
imprinted their footsteps; and the casts occur on overlying beds of 
sandstone, not exceeding two feet in thickness each. The best de- 
fined casts are those of a tolerably large animal, the hind feet of 
which measure nine inches in length by six across, and are about 
twice the size of the fore feet, the impressions of which latter are 
always immediately before the tread of the hinder, by which, in 
some instances, they are even partly effaced: in one case, the track 
of an individual was traced for sixteen feet along a single slab of 
sandstone. Although the footsteps of Cheirotherium are the most 
prominent, yet the Storeton quarries have yielded slabs covered by 
raised casts, derived apparently from Tortoises and saurian reptiles, 
the webs between the toes of which can be distinctly traced ; and nu- 
merous smaller casts are very abundant, crossing in all directions, 
and proving that, at the period when these layers of clay and sand- 
stone were deposited, the locality was thronged by multitudes of 
living animals. A note by Mr. J. Yates was: appended to the re- 
port, giving a brief account of sketches of four distinct varieties of 
impressions, not including those of the Chetrotherium, or the web- 
footed animal. The next paper was by Sir Philip Grey Egerton, 
and was also “ On the Cheirotherium.” The two specimens parti- 
cularly described were believed to have been obtained from one of 
the beds of sandstone which alternate with marl, in the upper part 
of the new red formation, near Tarporley. Sir Philip clearly 
showed that the marginal digit, or perhaps appendage, the exact na- 
ture of which is not obvious, but which had been considered as a 
thumb, would bé the representation rather of the fifth than of the 
first toe, as its position was outward, unless, indeed, the animal 
crossed its feet in walking, which was altogether improbable. The 
casts of impressions which he now described being evidently those’ of 
a different species from the animals of Hessburg and Storeton, he 
proposed to term it, in compliance with the adage ex pides Hercu- 
lem, from its very superior size, Cheirotherium Hercules.
