SUMMAET. 



All the species of the genus Astrocoenia which were described in 

 the ' Supplement to the British Possil Corals/ Pal. Soc. 1867, from 

 the Infra-Lias of South Wales belong to that genus, and not to 

 Stylasti-aa, Be Prom. The drawing of Astrocoenia plana, nob., 

 given by Mr. Tomes, does not correspond with the type specimen of 

 the species. Stylastrcea sinemuriensis and S. Martini, De From., do 

 not form part of the fauna of the Infra-Lias of South Wales. 

 Cyathoccenia, nob., is not the same as Phyllocoenia, Laube, which is 

 Koilocoenia, nob. The St.-Cassian Phyllocoenia decipiens, Laube, is
