absent, and the Obolus sandstone has not been reported at all. At 
most localities the Ceratopyge limestone has a much better develop- 
ment than in the more northern belts, though in a few places it is 
entirely absent. In most sections, the Planilimbata limestone is 
absent and the graptolite-bearing shales replace it. The Asaphus 
limestone of this region is similar to that of Oeland and unlike that of 
other regions in that Asaphus expansus itself is absent from the fauna 
and the Asaphuskalk is divided into two members by a stratum which 
is almost entirely made up of the cystid Sphaeronis pomum Gyllen- 
hahl.

The Ceratopyge limestone is a light gray limestone with light green 
glauconite and considerable pyrite in certain layers. Beside the 
typical fossils, which are somewhat abundant, Lycophoria laevis Stolley 
has been reported from this locality by Wiman (90). 
The Orthoceras limestone here has been subdivided into four 
divisions, on the basis of color. 
The lower twenty meters are of a deep red color and are known as 
the “Lower Red.” Above is found a band three meters in thickness 
of light gray limestone, the “Lower Gray.” At the top of this there 
is a sudden change again to deep red limestone and shale, not well 
exposed except for the two meters at the base, but perhaps thirteen 
meters thick. This is the “Upper Red,” and it is followed by the 
“Upper Gray,” sixteen meters of which could be measured. Fossils 
are common in the lower part of the Lower Red” and in the “ Lower 
Gray” but rather rare elsewhere, and it does not seem to have been © 
possible so far to make exact subdivisions on the basis of fossils. The 
color divisions do not, however, seem to correspond to the subdivisions 
which would be made on the basis of the fauna. The “Lower Gray”’ 
includes the “Sphaeronis bank” and with the upper part of the “ Lower 
Red” and the lower part of the “ Upper Red,” represents the Asaphus- 
kalk. On the basis of fossils it would appear that all the usual zones 
of the Orthoceras limestone, except the Planilimbatakalk and possibly 
the Gigaskalk, are present.
