Among the numerous fossils obtained by Dr. L. Moysey from the clay-ironstone nodules of the Coal-measures near Ilkesťon, Derbyshire, is one referred to by its discoverer as “a shrimp-like animal,” in a recent note published by him in the Geological Magazine for May last. Dr. Moysey was so fortunate as to secure several well-preserved examples of this very interesting Schizopod Crustacean from a disused brickfield on the Shipley Hall Estate, owned by E. M. Mundy, Esq. These he most liberally placed in my hands to examine and describe. Dr. Moysey also commended me to the Rev. C. Hinscliff, M.A., of Craig Royston, Bickley, Kent, who had in his possession another specimen of this crustacean obtained from the same locality. Mr. Hinscliff not only sent me his fossil to study, but generously presented it to the Geological Department of the British Museum (Natural History Branch), Cromwell Road, where it will be preserved and exhibited

The Lower Old Red Sandstone of Forfar and Kincardine is upwards of 14,000 feet in thickness. No indication of a base or natural top is seen in the district. The characteristic fossils of this series have all been obtained from its middle beds within a vertical range of less than 4,000 feet. There is no palæontological evidence of the age of the beds above or below that zone. It is concluded, on physical and palæontological grounds, that the fossiliferous beds of the Orcadian area are really younger than those of Forfarshire, but there is no proof that the higher part of the Forfarshire series was not contemporaneous with the Orcadian deposits.

The folding of the Lower Old Red strata into the syncline and anticline parallel to the Highland boundary fault took place subsequently to the deposition of the whole of those strata. This folding, and denudation to the extent of 8,000 feet over the anticlinal axis, were accomplished after the deposition of the Lower and before the beginning of the Upper Old Red. The surface on which the Upper Old Red rests, in Forfarshire, is broadly horizontal, but very uneven—evidently an old land-surface.

Of the places where undidtrubed limestone trested on older rocks, the most important visited by us was the valley of Hount-Sainte on the Spanish slope. This does not appear to have been considered by Carez, nor to have been hitherto described in detail. The fololwing sequence is clearly exposed, in descending order:—

4. Palæozoic—Devonian and Carboniferous according to Bresson. Shales and limestone in the lowest part, the base evidently a plane of disturbance.

My observations at Gavarnie commenced with the detection of the great fault of the Cirque, sketched in Bull. Soc. Géol. of 1868, and are summarized in my “Pyrenean Geology,” pp. 169, Dulau & Co., completed to 1907. The Hippurite limestone having been classed and mapped as typically metamorphosed Cambrian, on the ground that my maps and descriptions are à priori inexact, I have recently been concerned with the rectification of the simultaneously asserted Triassic age of the gypseous marls, which I have found to be Tertiary and Cretaceous, from Biarritz to Cardona. Before 1868 the Hippurites of Gavarnie and Heas were already described as anomalous by Leymerie in his Manual and papers, and by Frossard in his “Guide du Géologue.” The only specifically determined specimen mentioned by Bresson is from “near the Hourquette d'Alans,” a point touching the never-questioned Cretaceous beyond the great fault, and situated at 600 metres above the anomalous sheet in question, as it is figured on Bresson's largest sections. The only fossil of his basal Ordovician I had long previously ascertained to be in a fallen fragment from a peak to the west, outside the rocks in dispute. His ‘fundamental section’ east of Gedre is a local accident due to a fault, and his section of the Cirque is wildly in contradiction to the real stratification, as well as his section of the Spanish slope of the pass of La Canao and the Hount Sainte. All these errors are corrected on his definitive map of the French Survey, and in the report of the meeting of the Société Géologique in the Pyrenees in 1906. At that meeting the theory founded by M. Carez on the contradiction of my description of Eaux Chaudes, of Bull. Soc. Géol. of 1893, was explicitly acknowledged to be baseless and untenable by that writer himself, as well as by all present.

Mr. Dixon has handed me a small collection of rock specimens from Gavarnie (Hautes Pyrénées) and the district to the east. Microscopic sections have been made of these, with the object of ascertaining whether the structures and composition of the rocks throw any light on the vexed question of the age of the metamorphism in the two areas specially dealt with in the preceding communication.

The geology of South Africa is once again being brought to the notice of European geologists in the able papers by Dr. Voit in the Zeitschrift für praktische Geologie. In the first instalment Dr. Voit follows Drs. Hatch & Corstorphine in correlating the Waterberg Sandstone with the Table Mountain Sandstone, which is a small matter perhaps, but as it would in Europe be equivalent to correlating the Old Red Sandstone with the Torridon Sandstone, it is necessary to state the objections to this correlation and enable geologists to judge for themselves whether it is right or wrong.
