before the volume of the ' Paleontologie Frangaise ' appeared which 

 contains their diagnosis of the new genus, I had established the equi- 

 valent genus Antillia, which therefore must have the precedence *. 

 Lonsdale, in a MS. in my possession, proves that he had studied the 

 Antillice ; but he regarded them as Circophyllice. The stout epitheca, 

 which is so persistent in Antillia, separates it as a genus from Cir- 

 cophyllia, which has none, or only a trace. There is, of course, a pos- 

 sibility that the epitheca may be worn off during rolling ; but it could 

 not be so affected without damaging the costee. If, therefore, the 

 costse remain prominent, with a small rudimentary epitheca, it is ad- 

 visable to class the form possessing these attributes amongst the Cir- 

 cophyllice, Edw. & H. Hence I consider that, as Reuss has sagaci- 

 ously hinted, Cyatliopliyllia annulata, Ileuss, from Monte Viale 

 (Oligocene), should be termed Circophyltia annulata, Beuss, sp.

1. GONIASTR^A VARIABILIS, spec. nOV. PI. XXI. fig. 11. 



The corallum is massive, ovoid and depressed in shape ; and the 

 corallites radiate from a small base. 



The upper surface is slightly convex, and is crowded with calices 

 of different sizes, and all more or less angular in outline. 



The walls are thin, united, and slightly wavy. 



The fossae are shallow ; and the columellas differ greatly in their 

 development. Usually they are spongy and well developed ; some- 

 times they are distinctly linear, and formed by one lamella ; and in 

 some young corallites the columella barely exists. 



The septa are alternately thick and very slender ; they are short 

 and wide apart ; they are few in number, and are without distinct 

 cyclical order. 



There are some calices with 12, and others with septa reaching to 

 40 in number, and many intermediate sizes. 



Eissiparity is frequently observed. 



Height of the corallum 1^- inch. Length 3 inches. Breadth 

 2| inches. The long axis of calices from -fjj to ^ inch. 



Loc. The conglomerate of St. Bartholomew's. 



In the collection of Mr. P. T. Cleve, Stockholm. 



The nearest species with which this can be associated is Gonias- 

 trcea solida, Edw. & H., which is found in the recent fauna of the 

 Red Sea and the Seychelles, and which forms part of the raised reefs 

 of the Arabian shore of the Red Sea. 



The lamellar condition of the columella in some corallites is very 

 interesting, and foreshadows the genus Lamellastrcea (Duncan, Foss. 

 Corals "West Indies, part iv. p. 20, Quart. Journ. Geol. Soc. vol. xxiv. 

 1868).

1. SoLENASTR-EA COLUMNARIS, ReuSS. 



This species was found by Catullo at Montecchio Maggiore, and 

 was described by Rcuss from Monte delle Carrioli, near Polesella, in 

 the Castel-Gombcrto district.
