Light grey to greyish- green, phosphoritic and pyritiferous soft shales, free 

 from fossils, containing about 14 black phosphoritic layers or bands 

 of shale 0,01 — 0,03 m. thick ; in the lower portion a 0,03 m. layer of 

 light grey phosphoritic and pyritiferous clay 1,66 m. 



Conglomerate (phosphoritic balls in black shales with pyritic concretions) 0,08 » 



Lower Asaphus limestone. 



Limhata limestone. 



At HuUegaard, in the western bank of the river Lsesaan, the light grey 

 soft shales with layers of dark shale were observed for a distance of 50 metres. 



The stratigraphy of the Asaphus region tor the above localities is given for 

 purposes of comparison on p. 33 (scheme). 



As a result of my researches it may be definitely stated that the series of strata 

 between the Clingani-shale and the conglomerate above the Orthoceras limestone 

 in S. E. Scania is equivalent to the lower portion of the Middle Dicellograptus 

 beds and the upper portion of the Lower Dicellograptus beds in W. Scania. Con- 

 temporaneous strata in Bornholm are the zone of Aniplexograptus Vasae Tullb. 

 and the zone of Climacograptus rugosus Tullb., together with the light grey soft 

 shales with the dark shales and the conglomerates lying above. The conglo- 

 merates above the Orthoceras limestone in Bornholm and in S. E. Scania show 

 that a considerable lack in the stratification has here occurred during the period 

 of the depositing of the Upper Didymograptus beds and the greater part of 

 the Lower Dicellograptus beds in W. Scania. The Coscinorrhinus-zone, the soft 

 shales with Orthis shales etc., and the Ampyx limestone have the majority of 

 their fossils in common, are in a great measure of about the same age, and be- 

 long to the upper part of the Asaphus region. The soft shales of Bornholm may 

 be assumed to be in parts somewhat older than those of S. E. Scania. The posi- 

 tion of the Orthis shale (the siliciferous shale of the zone of Orthis argentea His.) 

 in the Ordoviciau system has been determined by my researches. I have not found 

 typical Orthis shale in Bornholm. 



The scheme on p. 47 is designed to show how, on the basis of my researches, 

 I have conceived of the arrangement of the different zones within the Asa- 

 phus region, to which region I refer, as far as graptolite or mixed facies are con- 

 cerned, all deposits between the zone of Didi/mograjjtns halticus Tullb. and the 

 zone of Dicranograptiis Clingani Caeb. The scheme shows, among other things, 

 that the Asaphus region is universally concluded by an Echinosphaerite zone, 

 except in Bornholm.
