1. A definite step in the progress of the solution of the problem 
presented to geologists by the confused highly fossiliferous strata of 
the eastern part of the Eastern Counties has been made, on the 
one hand, in the recognition of the character of the fauna of the so- 
ealled <<‘ coprolite-” or bone-bed of Suffolk, as distinct from that of 
the superposed shelly strata known as Coralline and Red Crags; and, 
on the other hand, in regarding the fauna of the Norfolk stone-bed, 
first recognized by Mr. Gunn, as distinct from that of the superposed 
shell-beds of the Norwich Crag. The bone-bed underlying the 
Suffolk Crags and the stone-bed underlying the Norfolk Crags must 
be looked upon as having a different history and containing a quite 
distinct fauna from that indicated by the Mollusca of the higher 
beds, the two not having been contemporancous, nor related to the 
same physical conditions. Until quite recently, these two distinct 
sets of accumulations have been confounded under the common term 
Crag. It is a matter for regret that the term Crag, locally applied 
to the shelly strata of the eastern counties, should also have been ex- 
tended to the whole series of deposits of Antwerp; for whilst the upper 
or Yellow Crag, forming the Scaldisien system of Dumont, is clearly 
equivalent to our Red and Coralline Crags, the Lower or Black Crag, . 
better called Diestien, is not represented in England by any exist- 
ing strata in their true position, and is simply connected with the 
“Crags” by a continuity of fauna and succession, which is not so 
complete as to prevent avery wide and marked gap being observable 
between the Diestien and Scaldisien periods,—-a gap indicating, pro- 
bably, great change of temperature and the disappearance of remark- 
able marine mammelia, as well as fishes and mollusca. In England,
