OX FOSSIL POLTZOA. 143 



by Reuss, Gabb and Horn, and Roemer. The list is therefore, for the 

 present, a compilation rather than the result of special work, and it may 

 in the future have to be modified. The recent species are very few, and 

 their range is limited. In the British seas only one is recorded ; in the 

 Mediterranean Mr. Waters records three species, and as these have fossil 

 representatives as well as recent, I give Mr. Waters's list first — ' Bry 

 Bay Naples,' 'Ann. Mag. Nat. Hist.' 1879.

 Range. — Coralline Crag. 



Genus Diastopora, (part) Lamx. 



Berenicea, Lamx ; Mesenteripora, Blainv., Busk (for foliaceous 

 bilaminate forms). Discosparsa, D'Orb. 



' Zoarium adnate and crustaceous, or foliaceous, usually discoid or 

 flabellate, less commonly irregular in form. Zaiocla tubular, with an 

 elliptical or subcircular orifice, crowded, longitudinally arrano-ed in 

 great part immersed.'— Hincks, ' Brit. Mar. Pol.' p. 457. 



The Diastoporas of the Tertiary rocks, even as defined above, which 

 include the foliaceous forms, are not abundant. So many different forms 

 have been included in the group that it is difficult from the lists to say 

 which are true Diastoporaa and which are not. The following, however 

 are the identifications of two of our best workers on Recent and Tertiary 

 Bpecies ; so the synonyms may be relied on as being; tolerably correct
