The church-tower of Eccles-by-the-Sea, on the coast of Norfolk, once buried in the moving sand-dunes, has been rendered classical by Lyell through his description of it in his “Principles.” Such a monument should surely not be allowed to pass away without an obituary notice.

Many of the preceding volumes of this well-known series may have possessed a wider interest, but few, if any, are of greater value, or will more profoundly influence the progress of seismology, than that which is now before us. This evidently is a work which is neither to be “tasted” nor “swallowed,” nor even to be “chewed and digested.” It is intended for those who make books, not for those who read them. It will be the parent of many papers. For in these somewhat unattractive-looking pages are gathered materials for the harmonic analyzer and facts for the student of terrestrial evolution. Only the labour is required, and that will soon be forthcoming, and we shall know something about the laws which govern the distribution of earthquakes in space and time, at any rate in the country where they have been most widely and successfully studied.

The new edition of Dr. Geikie's esteemed work has already been noticed at some length in this Magazine. The present writer desires to add some notes—freely, but with all respect to the author—on a special part of the subject, viz. that relating to the “high-level shelly deposits,” and their bearing on the question of submergence during the Glacial epoch.

Quite recently, Mr. B. B. Woodward, F.G.S., of the British Museum (Natural History), called my attention, for the first time, to the fact that the name Plutonia, which I adopted for a genus of Trilobites in 1868, had previously been used by Stabile (Atti. Soc. Ital. Sci. Nat. vii, p. 121, 1864) for a genus of Mollusca. As Stabile's generic term has therefore a priority of four years it is necessary that I should rename the Trilobite, and it has been suggested to me by Mr. Belinfante, B.Sc., Assist. Sec. Geol. Soc., that Plutonides would be the most suitable term and the one least likely to lead to confusion. In the Report of the British Association for 1868, p. 69, where the genus is first mentioned, after describing the beds in which it occurs I refer to it as follows: “The new genus, for which the author proposes the name Plutonia, is only known to occur in these beds. This remarkable fossil is of very large size, equalling, indeed, in this respect Paradoxides Davidis. It is, perhaps, also more nearly allied to the genus Paradoxides than to any other known, but its peculiar character of being covered all over with very strong tubercles, associated with an unusual position for the eye suture, and straight, very long thoracic pleuræ, is sufficient to stamp it a new and distinct genus.”.
