Corallum simple, circular, and affecting the form of a plano-convex lens, with a thick, 
rounded edge, and a small, shallow, circular fossula. Sepfa very numerous (140 or 150), 
extremely closely set, of equal thickness and of equal height, but varying in breadth 
(from the centre to the circumference of the corallum), and very delicately and regularly 
denticulated ; the smaller ones joining the neighbouring large one at their inner edge, 
so as to make the latter appear to bifurcate. In general, forty-eight principal septa reach 
to the edge of the fossula. The under surface is often concave. Breadth, six or seven 
lines. Height, three lines. 
The genus Anabacia has been very judiciously established by M. D’Orbigny’ for 
those simple, lenticular corals which had been usually placed among the Fungia or the 
Cyclolites, but differ from them by the absence of the mural disc. dAnabacia orbulites 
was the first species known to naturalists, and good figures of this fossil were given in 
the works of Plot and of Knorr. Three other species present the same generical 
characters, but are easily distinguished from it, specifically, by their general form; one 
of these, 4. Mormaniana,’ being very flat; the second, 4. hemispherica,® beng on the 
contrary much taller, and more convex; and the third, 4. Bouchardi,* bemg almost conical. 
Anabacia orbulites appears to be a common species. Specimens found in the Bradford 
clay at Bradford, and in the Great Oolite at Comb-Down, are in the collection of the 
Geological Society. Mr. Walton and Mr. Pratt have kindly submitted to our investigation 
other specimens found at Hampton, near Bath. Mr. Lonsdale mentions its occurrence in 
the Cornbrash at Atford, and W. Smith met with it at Broadfield Farm five miles from 
Bath, near Phillips Norton, Somersetshire. It has also been found in the Inferior Oolite ; 
Mr. Bowerbank and Prof. Phillips have communicated to us specimens from Dundry, and 
Mr. Walton a specimen from Charleomb. 
The same fossil is found in France, in the Great Oolite near Caen, Departement du 
Calvados, and in the Inferior Oolite at Conlie, Departement de la Sarthe. Goldfuss 
mentions also its occurrence in the Swiss Jura,
