 baltica of Lonsdale. Schtveigger's 

 Strombodes which is accepted hy M. 

 Edwards for these forms does not con- 

 tain a single of them. Synonymous with 

 this genus are Actinocyathus D'Orb., 

 Cylicopora Stein,, DarM-inia Dyb., La- 

 raellopora Dale O^ven. S, D.

Archaeocyathus Billings 1861. 

 Geol. Surv. of Can., reprinted in 1865, 

 Pal. Foss. of Canada, I, 3. In all pro- 

 bability a spouurian, as well as the prece- 

 ding. B. has fouud spicula in the ex- 

 terior wall, but more miuute researches 

 are necessary. 



Arthrophylluni Beyrich 1850. 

 Zeitschr. d. deutschen Geo]. Gesellsch., 

 10. According to Ad. F. Roemer, Pa- 

 laeoTitogr. Ill, 75. 18.')4, a very doubtful 

 genus aud is by R. described 'as an Or- 

 thoceratite, 0. crassum.

 Also written Aspidophyllum, uncertain 

 whether uot only a form of Clisiophyllum.

Astrceophyllutfi Nicholson & Hr; 

 1874. Canad. Journ. XIV, 152. Ac- 

 cording to a kind note from Mr G. J. 

 HiNDE he now considers this coral as a 

 silicified and weathered specimen of some 

 Strombodes (? = Arachnophyllum). 



Asti\^opot*a D'Orrigny & Mac Coy see 

 Astreopora. 



^Astrea Lam. 1816. An. a. vert. II, 

 257. Lonsdalk and Hisinger apply 

 this name to several species of Acervu- 

 laria and Cyatbophyllum. 



Astreopora Blalwille 1834. Ma- 

 nuel d'ActinoIogie, 383. Contains onlv 

 recent tpecies, but Mac Coy in Carbonif. 

 Fossils of Ireland, 1844, p. 191, used 

 it to name a corals the true nature of 

 which seems not to be yet cleared up, 

 ut is generally considered as one of the 



Heliolitidae, though none of that family 

 is known from the Carboniferous nera. 

 In British Fossil Coral, p. 18 Mac Coy. 

 cites the name for a species of Plasmo- 

 pora. D'Orbigny always wrongly states 

 M'CoY as the author,

 Heliolites. 



Aiilacophyllnm Edw. H. 1850. Brit. 

 Foss. Cor. hvii. Geuus of doubtful 

 value, as the type A. mitratnm, is one 

 of the most variable forms, displaying 

 almost all the characteristics of the so 

 called Cyathophylloid genera. 



Aulophyllum Edw. H. 1850. Br. Foss. 

 Cor. lis. According to Morris the same 

 as Clisiophyllum but in^nff'ciently known. 



Anlopora Goldfuss 1826 — 33. Fetref.

 Syringopora. 



Axinura Castelnau 1843. Essai snr 

 le systeme silurien de TAmer. septen-

 description are very unsatisfactory; »voi-

 terne qui s'etend dans toute sa lon-

 the first authors statements. D. 



Beatricea Billings 1857. Kept. 

 Geol. Survey of Canada, 343, described 

 at first by the author as h plant, has 

 for some time been considered as a coral 

 in affinity to Cystiphyllum, but is now 

 by some classed amongst the Cephalopoda. 

 . Beaumontia Edw. H. 1851. Pol.

 one of the Chsetetidte and consequently 

 a bryozoan. May also include some 

 Favosites.

 Blotkrophyllum Billings 1859. Dev,

 Clisiophyllym in having the diaphragms

 in the peculiarities of Amplexns and 

 Cyathophyllum.
