Amongst the Simple Corals with plain entire septa are some 

 which have been grouped generically, according to the presence 

 of- abundant endotheca or its comparative absence. This is not a 

 sufficiently important distinction. Thus the genus Cylicosmilia, 

 Milne-Edwards and Jules Haime, 1848, really only differs from 

 Parasmilia of the same authors by its more numerous septa and 

 well-developed endotheca. The first-named genus is of Eocene 

 age and the other is Cretaceous. 



It is necessary to absorb Cylicosmilia in Parasmilia, and to 

 alter the generic diagnosis of the latter slightly. 



Pourtales originated the genus Ccenosmilia, ' Deep-sea Corals 

 Hasslar Expedition,' p. 39 (1874), but in the description of the 

 corals of the ' Blake ' Expedition he withdrew it, and placed the 

 species in Farasmilia. 



Tribe I. 



Grenus Paeasmilia, Milne-Edwards ^ Jules Saime {Gonvpt. rend. 

 1848), and Brit. Foss. Corals, Introd., Pal. Soc. Land. 1849, 

 p. xxv, amended. 



Syn. Ccenosmilia, Pourtales ; Anomocora, Studer ; Cylicosmilia, 

 Ed. & H. 



The corallum is simple, fixed, subturbinate, or conico-cylin- 

 drical. Calice circular in outline. Columella spongy. Septa 

 entire, exsert, well developed, granular laterally. The wall is 

 naked and costulate. Endotheca exists. 



Distribution. — Fossil. Cretaceous and Eocene : Europe. Cre- 

 taceous : England. — Becent. Caribbean Sea, Philippines. 



Pourtales named the species Parasmilia Lymani and P. 

 variegata, from the Florida seas ; but in his last work, on the 

 ' Blake ' corals, he considered them very abnormal, and therefore 

 established the genus Dasmosmilia for them. But he retains 

 Parasmilia fecunda, Lindstrom (Pourtales, sp.), and notices that 

 the gemmation is not real, but that the young forms have settled 

 on a dead one.
