I. Introduction. 



Although Zoantharia belong to those fossils which were among the first to attract the 

 attention of collectors in Denmark, both on account of the frequency of their occurrence 

 in our chalk and tertiary deposits, and because of their striking appearance, yet not until 

 very recently has any attempt been made to classify and describe these animal remains. 



Forchhammer^) — ^) mentions in nearly all his fossil series the appearance of one or 

 two species of Turbinolia from Katholm, Møen, Faxe and the Cerithium chalk from Stevns 

 Cliff, but he makes no attempt to determine these fossils more exactly. 



That it seemed desirable to classify them is proved by the fact that the Zoological 

 Museum contains remains of corals, for the most part the stone kernel of single corals, 

 partly classified and named as follows: 



Turbinolia faxoensis, 



— b re vis, 



— ponderosa, 



— biser iata, 



— pusilla, 



— crassa, 



— ambigua. 



No small amount of work had been done with the corals as may be seen from a table, 

 preserved in the archives of the Museum, in which is printed a list of Danish fossil corals. 

 This was prepared as table III of a contemplated large work on Gaea danica. The two first 

 tables, (tables I and II) dealt with octocorals, and were published in my paper: Moltkia Isis, 

 Stp. og andre Octocorallia (Vid. Selskabs Skrifter. Mindeskrift for .Japetus Steenstrup XVIII). 



As it proved possible to find the originals of all the cuts shown in table III, this table 

 is now being published in its original form as table III of this paper.
