Polyzoa and Antliozoa from Upper Cretaceous Limestone. 11 



boundaries between them are clearly marked by thin ridges. Next 

 to Tervia dorsata (von Hagenow), this is the commonest species of 

 Cyclostome among the material here described. 

 Distribution. Neocomian to Danian. 



ANTHOZOA. 



In the Need's Camp material are several specimens of simple 

 corals, thickly encrusted with Cheilostome Polyzoa. Transverse 

 sections show that they belong to the genus Garyophyllia, but the 

 species cannot be determined owing to their encrusted condition.
