Funyia has several synonyms, whicli are as follows": 



Cyclosekis Milne Edwards and Hainie, Comptes rend. Acad., Paris, XXIX, 

 1849, p. 72. 



The jjenus was placed hy its authors in thcii- •' Loplioserina','' which was character- 

 ized b3^ having ''the plateau without epitheca or echiriulations, and with imperforate 

 tissues." 



Original generic diagnosis. — "Coralluui simple, free. Septa very numerous, 

 tmiting by their inner margins." 



Ti/jn'-yjecieit. — Fungia ci/cIoJites Lamarck, Hist. Nat. Anim. sans Vertebres, II, 

 p. 236: Doderlein, Korallengat. Fungia, pp. 77-70, pi. iv, tigs. 7-9, pi. v, figs. 5, 5a. 



Distribution. — Recent, China Seas and Philippines eastward to the mid-Pacific. 



AcTiNOSERis d'Orbigny, Note sur des Polyp, foss., p. 12, 18-19. 



Original generic diagnosis. — "It is a circular Cycloseris, whose columella is 

 central, round, and not in an elongated furrow." 



Type-speeies. — A. cenomanensis iXO\-\y\.<g\\^ , Note sur des Polyp, foss., nom. nud.; 

 Prod, de paleontol.. II, p. ISO: Milne Edwards and Ilaime, Hist. Nat. Corall., 

 Ill, p. 53. 



Distribution. — "Groupe de la craie tuffeau, Le Mans." 



Miln(> Edwards* refers Act inuseris cenotnanensis to the genus Cycloseris, making 

 d'Orbigny's Artinoseris a sj'nonym of their Cycloseris. The septal structure of 

 d'Orbigny's genus should be investigated, and it may be well to reinvestigate the 

 Tertiary and Cretaceous species of Cycloserift; thej- may not be congeneric with 

 Fungia (Cycloneris) cycloliten Lamarck. It is of especial importance to determine 

 whether the free disks of these corals placed in Cycloseris originate as anthocyathi, 

 as in Fungia. 



DiASERis Milne Edwards and Haime, Comptes rend. Acad., Paris, XXIX, 

 18-19, p. 72. 



This genus was placed by its authors in their " Loplioserina'," characterized hy 

 having "the plateau without epitheca and echinulations, and with imperfoi-ate 

 tissues." 



Original generic diagnosis. — "Differs from the preceding [Cycfos<»'is] in that, 

 when young, it is composed of separate parts that unite later." 



Type-species. — Fungia distorta Micht'lin. Mag. de Zool., -1^ ser., V Ann^e, 

 Zooph., pi. v: Doderlein, Korallongat. Fungia, pp. 7-1—77, pi. in. and pi. v, tigs. 3, 3«. 



Dixtrdiuthm. — Philippines. 



Remarks. — Duncan in his " Revision of the Genera and Families of the Madre- 

 poraria"*^ places Fcmc^^us Philippi'' and Umiiryathus Seguen/.a' in the synonymy of 

 Diaseris. Ecmesus is a doul)tful coral, but proliably is an imperfect specimen of a 

 troehocyathoid species. The llemicyatlnm of Seguenza certainly belongs in that 

 group.
