Tullb., Remopleurides sexlineatus Ang., Ampyzx rostratus Sars, Dal- 
manella argentea (His.), Corynoides calicularis Nich., Dicranograptus 
clingant Carr., Diplograptus quadrimucronatus Hall, Climacograptus 
scharenbergi Lapw., and Ptychopyge ? glabrata Ang. The zone of 
Dicranograptus clingani is at the base of the Chasmops beds, and the 
zone of Pleurograptus linearis at the top. | 
The fauna of the Lower Dicellograptus shales has been monographed 
by Hadding (60), who lists the following as characteristic fossils of 
the thin-bedded gray-black shales which make up the strata of the 
three subzones in Scania. 
Subzone of Nemagraptus gracilis— Nemagraptus gracilis remotus 
Elles & Wood, Lasiograptus mucronatus Hall, Obolus elatus Hadding, 
Plectambonites sericeus restrictus Hadding. 
Climacograptus putillus zone.— Climacograptus putillus Hall, C. 
caudatus Lapw., Dicellograptus vagus Hadding, and Dicranograptus 
erregularis Hadding. 
Glossograptus hincksi zone.— Glossograptus hincksi Hopk., Crypto- 
graptus lanceolatus Hadding, and Diplograptus perexcavatus Lapw. 
The Upper Didymograptus beds consist of green and gray shales and 
the fauna seems to be incompletely known. 
In the Didymograptus geminus beds.— D. geminus Hisinger, 
Lonchograptus ovatus Tullb., Climacograptus confertus Lapw., Ptero- 
graptus scanicus Moberg, P. elegans Holm, and species of Diplo- 
graptus and Cryptograptus have been reported. 
From the lower zone.— Phyllograptus cf. typus, Didymograptus 
cf. bifidus, Climacograptus and Cryptograptus are reported. It seems 
to be a sort of transition zone, in which the Diprionian graptolites 
which are so abundant in the beds above make their first appearance, 
but accompanied by some of the survivors of the more ancient 
fauna. 
The Orthoceras limestone is a hard, rather pure, dark blue limestone 
and is at present inadequately exposed. Angelin (58) described 
twenty species of trilobites from the quarries at Fagelsang, some of the 
more important of which are *Ampya nasutus Dalm, Asaphus acumi- 
natus (Boeck), *Cyrtometopus clavifrons, *Megalaspis limbata (Sars 
and Boeck), *Nileus armadillo Dalm, Symphysurus palpebrosus 
(Dalm), *Niobe frontalis Ang., *Pterygometopus sclerops (Dalm), 
Trinucleus coscinorrhinus Ang. The species marked with an asterisk 
occur in the Limbata or Expansus limestones of Sweden and in the 
zones By,g and Biya of Russia. 
According to Strandmark (81), beds of shale containing graptolites
