Gneiss, Granite, Syenite, Porphyry, Gabbro, Labradoritc. Diabase, and Diorite. 



The first division, or Etage 1, represents the zone of Paradox- 

 ides, and is equivalent to the zone of Paradoxides in Newfoundland, 

 Massachusetts, and New Brunswick. It is called " Paradoxides slates 

 of Krekling" near Vestfosen. After its deposit there was a disloca- 

 tion strongly marked at Sandswa^r near Christiania, which seems to 

 be contemporary with the dislocation at Newfoundland, St. Mary's, 

 Trinity, and Conception Bays, and St. John, New Brunswick. For 

 more than twenty years Prof. Kjerulf has recognized this i-esemblance, 

 and has placed this first division in the Taconic System. The fossils 

 are : Paradoxides Kjeridji, P. Tessini, P. rugidosns, and /-*. Forchham- 

 ineri ; Arionellns primei^its ami A. dijformis ; Counccphalites ornatus, 

 and C. Sidzcsi ; EUi}>xncpj)halus circiliis ; Liostracvs Linnorsoni and 

 L. microphUiahnus ; Dolichoinetojius Sneciois ; twenty species at least
