Extract

During one of my last visits to England I had the opportunity of visiting a great number of palsæontological collections. Amongst those which afforded me the greatest pleasure, I would specially mention the collections of Mr. Edward Wood, F.G.S., at Richmond, in Yorkshire, and of Mr. John Gray, at Hagley, near Stourbridge.

page 261 note 1 When examined with a pocket magnifying glass, the plates of nearly all the specimens in the British Museum, now upwards of twenty in number, show a finelystriated ornamentation running in an obliquely-transverse direction across their surface. Probably the specimen examined by M. de Koninck may have been much rubbed upon its surface. In the publications of the Geological Survey of Canada, Decade III., “Figures and descriptions of Canadian organic remains,” Montreal, 1858, p. 72, Mr. E. Billings, the accomplished palæontologist to that Survey, has figured in a small woodcut and described an anomalous and imperfect Cystidean, under the name of Ateleocystites Huxleyi. From the figure and description we are inclined to think it may hereafter be shown to be the “posterior” surface of a cystidean, identical with M. de Koninck's Placocyslites Forbesianus; the more so as the plates are described by Mr. Billings as tranversely striated. But as the Canadian specimen is very imperfect, we think it would be very hazardous to assume from the figure alone that Placocystites (de Koninck, 1869) was synonymous with Ateleocystites, Billings, 1858.—Edit.
