Abstract

The paper deals with the stratigraphy and faunas of the upper Tremadocian and the lower Arenigian rocks of Sweden. Sections through these rocks from most of the Palaeozoic districts of the country are described and figured. The Iimestones examined are subdivided into trilobite zones, and an attempt is made to correlate some of these zones with the graptolite zones of the Arenigian Lower Didymograptus shale. Correlations are also proposed with the early Ordavieian beds of Great Britain, Norway, and the East Baltic. A number of new trilobite genera and species are described, and several old species, imperfectly known, are revised
