Some Phyllocarida from the Silurian strata of Scandinavia (Sweden and the Island of Gothland) are represented by specimens in the State Museum at Stockholm. Drawings, casts, or the specimens themselves have been shown to us by our friend Professor Gustav Lindström, F.C.G.S., and we have arrived at the following conclusions as to their relationships.—See the “Fifth Report on the Fossil Phyllopoda of the Palæozoic Rocks”, read at the Manchester Meeting of the British Association for the Advancement of Science, September 3, 1887 (printed and issued at the same date), pp. 1–3.

In 1881 Mr. J. W. Davis proposed the genus Anodontacanthus for certain straight spines resembling Pleuracanthus, but differing in the absence of the two rows of denticles. Three species are included:–A. acutus and oltusus, from the Coal-measures of Yorkshire, and A. fastigiatus, from the Blackband Ironstone of Carboniferous Limestone age at Loanhead, near Edinburgh.

As a text for the following brief remarks on the recognition of mural pores in thin sections of the Favositoid Corals, I may quote a note appended by Mr. James Thomson, F.G.S., to a recent paper on the genus Lithostrotion (Trans. Edin. Geol. Soc. vol. v. part iii. p. 381). The note in question is subjoined, the quotation being verbatim, and, I may add, literatim also:—

“We may, however, attach an undue importance to microscopic examinations. Need I refer to the point raised recently by that erratic and energetic worker, Prof. Alleyne Nicholson, regarding mural pores in the genus Alveolites, the type of which is also in Dr. Fleming's collection. If he had detected mural pores in microscopic sections, we would have regarded such as being one of the greatest discoveries of modern times.

A Recent examination of the remains of Tertiary Lacertilia and Ophidia preserved in the British Museum having brought to light some new facts in regard to distribution, and also indicating the necessity of revision of certain determinations of other authors, I have thought it advisable to communicate the result of my observations in a collective form.

The effect of the attraction of continental land upon the oceanic waters adjoining seems to have been very much overlooked by British physical geographers. That some slight effect arises in the direction of elevating the surface of the ocean in proximity to the coast is generally admitted, but the amount of rise is considered to be small, perhaps insignificant. The prevalence of these views was attributed by the author to the widespread influence of Lyell's hypothesis of the uniformity of the ocean-surface all over the globe.

A highly interesting and remarkable instance of altered Coal measures, due to impregnation by hydrous and anhydrous oxides of iron, infiltrated by water from the overlying Permian strata, can now be seen in situ in the Ashby-de-la-Zouch Coal-field, and I think it should be made known in order that those who may wish to study such phenomena may have the opportunity of doing so. The following is a general description of the section.

The remarks made by Mr. Haddow in the GeologicalMagazine, Decade III. Vol. IV. p. 519, seem to demand a reply.

1.—He complains of the multiplication of generic or subgeneric names of Ammonites.

2.—He laments the confusion which appears to have arisen concerning what have hitherto been regarded as recognizable species.

3.—He suggests that the trinomial system would obviate the necessity of any of these changes and be at the same time an advantage.

These notes are intended as an appendix to “Notes on the Erosive Power of Glaciers, as seen in Norway” (vide this Magazine, Decade III. 1887, Vol. IV. No. 4, p. 167).

1. The object of my visit to Norway and the Alps was to leave closet-geology in America, in order to make personal observations of the phenomena associated with modern glaciers,—for comparison with those in the region of our Great Lakes, often attributed to land-ice.

In “Nature”, August 26, 1886, vol. xxxiv. p. 387, I ventured to draw a distinction between the outliers of unfossiliferous Tertiary sands found at high altitudes on the North Downs and the deposits containing casts of fossils of Pliocene age which are found in hollows in the Chalk at Lenham. Last summer I visited and examined, I believe, all the more important outliers of the former series, Mr. J. Hutchins French, F.G.S., having kindly conducted me to those at Headley and Chipstead; those at Netley were visited with other members of the Geologists' Association under the direction of the same gentleman.

The occurrence of glaucophane has not, I believe, been previously noted in Great Britain, and as it is a mineral of some interest, my friend Mr. Teall has suggested that a separate notice of it should be given. It would otherwise be naturally described in the Report on the Microscopic Structure of Anglesey Rocks to be presented to the British Association at their forthcoming meeting.
