werp Tertiary deposits, seems to warrant the assumption that 
there existed previously, along the Suffolk coast, a Miocene and 
a Phocene deposit, the one abounding in terrestrial Mammalian 
remains, as the Epplesheim strata, the other in Cetacean fossils, 
as does the Middle Crag of Antwerp, and that the Red-Crag 
sea (and the Coralline also to a less extent) has entirely denuded 
and partially redeposited these strata in association with its 
proper Molluscan fauna, and perhaps with some Mammals, 
which, however, we are not able to designate. 
Before concluding this paper (for the errors and defects of which 
I beg the reader’s indulgence), I would wish to guard against 
the supposition that any of the Mammalia assigned to the Red 
Crag may have been obtained by mistake from the Mammali- 
ferous Crag. That deposit is never, so far as I am aware, met 
with in superposition to the Red Crag; and the dental remains 
from it are light, absorbent, and unmineralized, as compared 
with those from the lower bed. Moreover the species are very 
widely different which occur in the two, the only common spe- 
cies being the Mastodon angustidens, which in both eases is cer- 
tainly a derived fossil. The term “ Mammaliferous” would 
doubtless be more appropriate to the Red Crag than it is to the 
much later Norfolk formation.
