Extract

We are informed by M. Ferry that d'Orbigny was supplied with, the greater part of the Corals of his Bajocien by M. Eugene Beabeau, of Langres, who has stated of the present species that it was first named Calamophyllia glomerata by d'Orbigny, and afterwards by an error Synastræa consobrina, and further, that he at the same time described in his Prodromus another species under the same name. MM. Milne Edwards and Haime, it appears, were misled by this error, and referred the Coral sent by M. E. Beabeau, to the Synastræa consobrina of the Prodromus. This in brief is the statement of M. Ferry, and it is obvious that the Synastræa consobrina of the Prodromus, and the Clausastræa consobrina of MM. Milne Edwardsand Haime are not the same, and that the latter is the Coral forwarded by M. E. Beabeau from Langres.

page 446 note 1 Since writing the above the specimen figured by Prof. Duncan as Thecosmilia obtusa has come into my hands. Of it I shall have more to say on a future occasion.

page 447 note 2 I must differ wholly from Prof. Duncan when he says that there are never two rudimentary cycles in the same calice. There are not ever, to the best of my knowledge, two rudimentary cycles in the same system, but there may be, and often are, in the irregularly developed calices of Jurassic Madeporaria, rudimentary septa of quite different ages in different systems. The third cycle may be rudimentary in one and complete in another, in which a fourth may have even commenced its growth. Such irregularities are frequent after recent rejuvenescence, one side of the calice having perhaps the full complement of septa, while the other may have only the earlier developed cycles.
