stitute complete beds. This portion of the chalk series forms, very 
generally, the lower part of the strata in Seeland and Jutland, and the 
whole of the cliffs of Moen. But in Moen masses of gravel and sand 
have, in consequence of great disturbances, become entangled with 
portions of disrupted chalk, in the manner explained by Mr. Lyell in 
a paper lately read before the Society*. 
This white chalk is immediately overlaid, in Seeland and elsewhere, 
by the Faxoe beds, consisting almost entirely of hard, yellowish 
limestone, susceptible of a polish. They contain some of the cha- 
racteristic fossils of the white chalk and some which are peculiar, 
belonging to the genera Arca, Modiola, Venus, Trochus, Fusus, Vo- 
luta, Oliva, Cyprea, Nautilus, &c.; while in the quarries at Faxoe 
(Seeland) they are composed so largely of zoophytes that they may 
justly be regarded as a coral reef. ‘This division of the cretaceous 
series attains at Faxoe a thickness of more than 40 feet, but it is only 
between 2 and 4 feet thick at Stevensklint, where it may be traced 
for 3 or 4 miles resting upon the white chalk and covered by other 
strata of this series. The Faxoe beds appear also in some places in 
Jutland as in the Island of Mors, the cliffs near Grenaa, &c. 
These beds have been imagined to be perfectly parallel to those of 
Maestricht, but the organic remains differ considerably ; and are more 
analogous to those found at Kiinruth near Liege. Among the fossils 
common to the last locality and the Faxoe beds, are Baculites Fawasii, 
Nautilus fricator (Beck), Fusus elongatus (Beck), and 7 erebratulasubgi- 
gantea (Schlotheim). Dr. Beck also states that the Nautilus Danicus 
is not identical with the Nautilus aganiticus of the lias, though Von 
Buch considers that it is : he likewise states that he has not been able 
to identify any of the Faxoe fossils with those of the oolitic series, or 
with the shells of Gosau, or with any of the tertiary fossils hitherto 
described. 
The cretaceous beds which immediately cover the Faxoe deposit in 
Stevensklint, consist of a whitish and hardish chalk, including so great 
a number of broken and almost pulverised zoophytes that the rock is 
sometimes entirely composed of them. The bivalves and echinoder- 
mata are chiefly the same as those of the white chalk, but the univalves, 
so common in the Faxoe beds, are wanting, while many of the smaller 
corals which occur in those beds occur also in this upper limestone. 
The flint of these superior strata is sometimes in continuous layers as 
in Stevensklint, sometimes in nodules, and differs from the flint in the 
white chalk in being more opake, and having a less conchoidal fracture. 
Sometimes it is replaced by a bluish grey stone, composed of silex and 
lime, and called in Danish “ bleger.” 
Dr. Beck infers from the organic remains that the chalk of Salt- 
holm; of the cliffs in Jutland, ranging from Rugaard by Daugbjerg and 
Monsted, and terminating in the neighbourhood of Hjerm ; as well 
as the chalk of the south of Thyholm, that resting upon the white 
chalk in part of Mors and in the northof Thy; and the chalk of thecliffs 
of Bulbjerg and the islet Skarreklit belongs to this uppermost bed.
