KONGL. SV. VET. AKADEMIENS HANDLINGAR. BAND 25. N:0 9. 11 



To the Geheimrath CARL MOBIUS in Berlin I am under obligation for lending me 

 for examination good many examples belonging to the German State Museum; as also to 

 Professor W. DAMES, curator of the Geological-palaeozoic Departement of the Museum, for 

 his kind assistance in enabling me to examine the tertiarian and chalk Foraminifera 

 under his care. 



To my friend Cav. LUIGI m ROVASENDA at Sciolze it is a pleasant duty to express 

 my hearty thanks for his efficient assistance and kind hospitality while on a stay in 

 Piemonte last spring in search of tertiarian Foraminifera. I have also to acknowledge the 

 communicating of valuable papers and advices in connection with this essay from Prof. 

 FED. SACCO, Rev. ERM. DERVIEUX, Dr. G. DE AMICIS in Turin and from Dr. C. FORNASINI 

 in Bologna.
