EMENDATIONS OF AMMONITE NOMENCLATURE. a a TUM Gide WAH ON Ode I SAL Aaa EMENDATIONS OF AMMONITE NOMENCLATURE BY S.' ©. | BUCKMAN. It is now eighteen years since my ‘‘ Monograph of Inferior ? Oolite Ammonites” was commenced; and fifteen years since the first part was published. The knowledge gained during the progress of the work has shewn how general, particularly among retrogressive series of Ammonites, is the phenomenon of Homceomorphy ; and therefore that external similarity is no test of specific identity. The necessary result is a considerable revision in the specific nomen- clature, partly carried out in the two Supplements published—a revision based on a close study of suture and radial lines. But there are many species not touched in these Supplements, and final publica- tion may be unavoidably delayed. Meanwhile, I am constantly receiving for identification specimens of these species, both from this country and abroad: to them I cannot give the old names, and can only append the new at risk of misconception. ‘Therefore, to help others as well as myself, I have deemed it advisable to publish this informal list of the proposed revisions. 3 The names in heavy type are new. The references are to the Plates of the Monograph—the Roman numerals indicating the plate number ; the Arabic, the figures in the plate. 'T’ indicates the type of genus. HILDOCERATID&.

Corrected by Haug, Amm. Bull. Soc. Géol. France, Vol. xx. 1893. ZURCHERIA. - To the species in this remarkable and rare genus add Zurcheria pugnax (Vacek). The specimen is a whorl larger than Vacek’s, and shews, on this whorl, the ornament of Haplopleuroceras sub- spinatum, but with no trace of keel or furrow. It came from the Building Stone of Stoke Knap, Dorset. STEPHEOCERATIDAE. Zigzagiceras. gen. nov. Type. Am. zigzag, d’Orb. A Stepheoceratoid series in which the umbilical, or lateral, costae are distant and end in obtuse, elongate, somewhat angulate knobs, instead of spines. Further development produces a planulate, or Perisphinctean style of ornament, but without the periodic con- strictions of Perisphinctes. On the developments of the zigzag series see Morphology of ‘TStepo. ziezac;. Quart. Journ. Geol: Soc:, vol. XLVIII., p. 447. > 1892. NORMAN, SAWYER AND CO., CHELTENHAM, JUNE, I902. ‘ee!
