In a paper dated 1887 dealing with Stage 4 of the islands near 

 Kristiania, »Geologisk kart over øerne ved Kristiania« ^, Brøgger men- 

 tions the brachiopods very briefly, without as a rule giving specific 

 names. 



In 1897 J. Kiær, »Faunistische Uebersicht der Etage 5 des norwegi- 

 schen Silursystems« ^ gave lists of the fossils from Stage 5 of the various 

 districts of the Christiania region. He mentions:

 Strophomena rhomboidalis Wilck. 

 Strophomena deltoidea var, undata M'Coy, 

 Stophomena pseiidoddtoidea Stoll.

 Strophomena cf. grandis Sow. 

 Strophomona cornigatella Dav. 

 Leptaena sericea Sow. 

 Leptaena Schmidti Tqu.
