PREFACE 



If, in this paper, I have succeeded in presenting many new species of corals to the 

 pubUc, the credit is largely due to the fact that a foundation for my work has been laid 

 by others. Both of our own museums have possessed for a long time a large material, classi- 

 fied and determined. I owe warm thanks to Professor A. Jensen and Inspector, Dr. phil. 

 Mortensen of the Zoological Museum, and no less to Professor Boggild and Docent Ravn 

 of the Mineralogical Museum for their permission to make use of this. My thanks are also 

 due to Professor, Dr. phil. Grönwall of the University of Lund for the great interest he has 

 shown in my work and for the direct help he has given me. Without his valuable assistance 

 it would have been impossible for me to account for several of our single corals.
