^{page 203 note *} Antediluvian Phytology, illustrated by a collection of the Fossil Remains of Plants peculiar to the Coal Formations of Great Britain. By Edmund Tyrell Artis, F.S.A., F.G.S., London. In all the copies I have seen, the Introduction to the work is dated 1st September 1825, but the title-page bears the date 1838. This latter date is evidently that of a later issue, or second edition of the work, and may only be an alteration of the title-page of the copies subsequently issued. Each of the twenty-four plates contained in the volume bears the date of 1824. That the work was issued at least ten years before 1838 is evidenced by the fact that Brongniart quotes the book in his Prodrome d'une histoire des vegétaux fossiles, published in Paris in 1828. Probably, therefore, 1825 is the true date for the first issue of the Antediluvian Phytology.

^{page 203 note †} The Yorkshire Carboniferous Flora—

^{page 203 note ‡} The names of those to whom the Committee were indebted for assistance are given in these Reports. I am however, almost entirely indebted to Mr W. Hemingway for my fine series of Yorkshire specimens of Dactylotheca plumosa, Artis, sp., from which largely the present paper has been written.

^{page 220 note *} The forma dentata is much more common than any other in the Upper Coal Measures.

^{page 221 note *} I have also seen the crenata form from the Forest of Wyre, but do not know the exact locality from which the specimen was collected.

^{page 221 note †} Note.—The other specimens of Sphenopteris crenata, L. and H. (pls. c.-ci.), came from the Whitehaven Coal Field, but I have hitherto been unable to visit this Coal Field, so can express no opinion as to their age.
