The common English classification of the Palæolithic Period into the epochs of the River-Drift Men and the Cave Men hardly conduces to clearness of thought. The implements of the River-Drift men are often found in the caves, and those of the Cave Men are very common in the river drifts. Although the caves and rock shelters bring us down to a later period than is usually represented in the river drifts (there appear to be exceptions to this), yet the general succession in the two classes of deposits is the same, and they cannot be separated.

This species is fairly common in the Alveolina-limestone of the present series, occurring both in the powdered rock and in thin sections. For the previous occurrences of the species in Egypt see Geol. Mag., 1900, p. 7.

In the Geological Magazine for September, 1901, I pointed out that Sir Henry Howorth had done Professor Huxley a great injustice in charging him with having suppressed certain important evidence. In the Magazine for January, 1902, Sir Henry, instead of hastening to acknowledge his error, proceeds to deepen his guilt by joining the pack that yelps at the heels of the great Dean Buckland.

The geology of the Lleyn peninsula has from time to time attracted the attention of geologists, and several workers have added much to our knowledge of this district; but their researches have been mainly confined to (1) the strip of ancient rocks (usually assigned to the pre-Cambrian) in the west between Porth Dinlleyn and Bardsey Island, and (2) the igneous rocks lying in the Ordovician ground which occupies the eastern and larger portion of the peninsula. Thus the Ordovician sedimentary rocks have largely escaped attention, a result probably also due to their monotony, to the rarity of fossiliferous localities, and to the great extent to which the beds are concealed beneath accumulations of drift.

The original specimen (a 878) is in a very perfect condition and comes from the Wenlock Limestone of Dudley. It also belongs to the Fletcher Collection. There is no other specimen of this species in the Woodwardian Museum. Salter calls it “a new square species.”

In a recent number of the “Neues Jahrbuch” (1901, Bd. ii, Heft 3, pp. 158–170, 6 text illust.) Dr. J. F. Pompeckj, of Munich, has an interesting paper on the genus Tmaegoceras. The genus was established by Hyatt1 in 1889 for the two very rare Ammonites from the Lower Lias of the Alps, Ammonites latesulcatus, F. v. Hauer, and Arietites levis, G. Geyer. To these, in 1899, G. Bonarelli4 added a third species, Tmaegoceras Paronai, from the Lower Lias of the Central Apennines, at the same time assigning to this genus Schafhäult's Ammonites Helli. But as Mojsisovics pointed out in 1893, Schafhäutl's species is a Tropites, whilst Ammonites latesculcatus, F. v. Hauer, Arietites levis, G. Geyer, and Tmaegoceras Paronai, G. Bonarelli, have nothing whatever to do with that genus. Of these three species Dr. Pompeckj regards Ammonites latesulcatus, F. v. Hauer, and Tmaegoceras Paronai, G. Bonarelli, as generically identical, and with them he unites also Quenstedt's Ammonites dorsosulcatus and his own new species (T. crassiceps), which he describes from the Lower Lias (zone of Arietites Bucklandi) in the neighbourhood of Tübingen (Württemberg). He considers Arietites levis, G. Geyer, to be a true Arietite, probably related to Arietites ophioides (d'Orb.), Wähner, or Arietites Cordieri, Canavari.

Yarmouth and Lowestoft have long been connected by railways, but although the Great Eastern Company had provided a choice of routes, there was no direct way. This is now in process of construction by a joint arrangement between the Great Eastern, Great Northern, and Midland Railway Companies; and the route, for the most part within a mile of the sea-coast, is from the Great Eastern Station at Lowestoft through Gunton, Hopton, Corton, and Gorleston to the Yarmouth Beach Station, a distance of a little more than nine miles.
