I.— INTEODUCTION. 



During the year 1889 I had the pleasure, accompanied by my friend Mr. A. Smith 

 Woodward, to visit some of the principal Museums in Sweden and Denmark, and 

 to become personally known to those "who were in charge of them. The 

 collection of fish-remains from the chalk of South Sweden have received little 

 attention since the time of S. Nillson, who first discovered fish remains in the 

 Swedish chalk, and who described a few teeth in his work on the " Petrificata 

 Suecana, formationis Cretacese," published in 1827. Eleven years afterwards 

 W. Kissinger copied the plates of Nillson into his " Lethea Suecica seu Petrificata 

 Suecise," but does not appear to have advanced beyond his predecessor. Since 

 that time the number of examples of fossil fishes has largely increased, and the 

 collections are now of great interest. The present memoir is due mainly to the 

 suggestion of Dr. Bernard Lundgren, that the enlarged collections needed, and 

 were worthy of, renewed study ; and his offer, coupled with a subsequent one by 

 Dr. Gr. Lindstrom, to allow the specimens to be sent to England for this purpose, 

 was a sufficient inducement to me to accept it. An application to Dr. C Liitken 

 for the collection at Copenhagen was also readily granted, and others followed. 



I have unfeigned pleasure in expressing my great indebtedness to Dr. Gr. Lind- 

 strom, Keeper of Palaeontology, National Museum, Stockholm ; to Dr. Bernard 

 Lundgren of the University of Lund ; to Professor 0. Terrell, Director of the Geo- 

 logical Survey of Sweden ; to Dr. C. Liitken, Professor of Zoology at the University 

 of Copenhagen ; to Dr. F. Johnstrup, Director of the University Mineralogical 

 and Geological Museum at Copenhagen, and to others, for their great courtesy 

 and kindness in unreservedly placing the collections in their charge at my 

 disposal, and so affording me the best opportunities possible to identify and 

 record the occurrence of the fish remains which have been found in the chalk of 

 Scandinavia. Dr. Liitken has kindly furnished me with particulars of his own
