354 Mr. E. R. Lankester on new Mammalia 
from Middle Eocene beds. (6) Teeth of Mastodon angustidens, 
Rhinoceros Schleiermacheri, Tapirus priscus, and others, derived 
from the breaking up of a Miocene deposit of the same age as 
the Epplesheim strata. Remains of Mastodon have been found 
at the base of the Coralline Crag, in a débris formed of phos- 
phatic nodules and vertebrate remains. (7) Cetacean remains, 
consisting of bones and teeth, much worn, teeth of Carcharodon 
megalodon and Oxyrhina, also worn, derived from a previous 
Pliocene deposit, contemporaneous with the Middle Crag of 
Antwerp, where these same Cetacean remains and Sharks’ teeth 
are abundant in an unworn state. These also have been found 
at the base of the Coralline Crag. (8) Shells derived from the 
Coralline Crag—Pectunculus glycimeris, Pyrula reticulata, &c. 
(9) The proper fauna of the Red Crag, certain Fish-remains, 
Mollusca, Crustacea, and perhaps some Mammalia. 
It seems very certain that the majority of the terrestrial 
Mammalia obtained from the Red Crag have not only a Miocene 
facies, but are absolutely derived from a Miocene deposit, whilst 
the Cetacea are of a later period. In the equivalent of the 
Red and Coralline Crags at Antwerp not a single terrestrial 
mammal has been found; but Cetacean remains are abundant, 
and the teeth of a species of Phoca have been detected. The 
beds at Antwerp give indications of having been deposited far 
out at sea, in a much quieter manner than the Red Crag, which 
appears to have been a littoral deposit, and is in fact a raised 
beach, in forming which great districts of previous strata were 
broken up by the sea, which has now destroyed the greater part 
of the Red Crag in its turn. It is therefore not impossible that, 
in the process “of the formation of the Red Crag, remains of 
certain terrestrial mammals then living on the shores of its sea 
should have been imbedded; whilst in the Antwerp strata, more 
distant from the coast, the remains of none but marine beings 
could be enveloped. No Mammalia have, however, yet 
been found of which it could be said with any degree of cer- 
taimty that they lived contemporaneously with the Molluscan 
fauna of the Crag; and we may be confident, from the position 
in which they have been found, from their condition and pale- 
ontological affinities, that Mastodon angustidens, Rhinoceros 
Schletermacheri, Tapirus priscus, Felis pardoides, and other 
Miocene forms, did not live during the deposition of the Red or 
Coralline Crags. 
In looking over Mr. Whincopp’s collection, I found some 
Mammalian teeth which have not hitherto been noticed, a de- 
scription of which I trust may prove of some value as an addi- 
tion to our knowledge of the fauna of the Red Crag and of the 
British fossil Mammalia generally.
