346 RHINOCEROS. 
of bones, discovered by the Rev. R. Greaves in a fissure 
of a limestone rock in Caldy Island, off Tenby, most of 
which proved to belong to the Rhinoceros tichorhinus. A 
femur of the same species was discovered by Dr. Lloyd in 
a fissure of the Aymestry limestone. Mr. Murchison, who 
cites Dr. Lloyd’s discovery, proceeds to say, (loc. cit. 
p- 554) :— 
“That quadrupeds of extinct species inhabited this 
(silurian) region, is proved by the contents of certain. 
gravel heaps on its eastern limits. In a pit, south of 
Eastnor Castle, where the fragments consist exclusively of 
silurian rocks and syenite of the adjacent hills, the remains 
of the Elephant and other animals have been found, and 
at Fleet’s Bank, near Sandlin, the bones of a Rhinoceros 
and Ox. The latter were found by Mr. J. Allies, who 
has also collected the bones of the Horse, Rhinoceros, 
Elephant, &c., at Powick, and those of a Rhinoceros at 
Bromwich Hill, near Worcester.” 
Remains of the Rhinoceros were discovered by My. Strick- 
land, associated with those of the Elephant and Hippopo- 
tamus, in the fluviatile deposits of the valley of the Avon, 
near Cropthorn, Worcestershire. These deposits appear to 
form part of the same series which he has traced from Defford, 
in that county, to Lawford, in Warwickshire, where they 
have yielded bones of the Rhinoceros in great abundance and 
perfection. Remains of this Pachyderm were likewise 
associated with those of the Elephant and Hippopotamus 
in the analogous fresh-water deposits of the valley of the 
Thames. The tooth, figured in Mr. Trimmer’s Memoir on 
those at Brentford (Philosophical Transactions, 1813, pl. 
ix. fig. 2), is an upper molar of a Rhinoceros, not of the 
Hippopotamus, as there stated.
