The use of the terms “normal” and “abnormal” in relation to shore-platforms has led to confusion and should be discontinued. Processes operative in the formation of shore platforms are analysed from Victorian examples. The effects of water-layer weathering, growth of marine organisms, breakers, and waves of translation on sheltered and open coasts and on various rocks (including a special study of platforms in aeolianites) are discussed.

The Ordovician genus Corynoides Nicholson has until recently been very imperfectly known and generally neglected. Its development and peculiar morphology are discussed, but its systematic position amongst the graptolites remains doubtful. Four European species are here described and figured, one being new, and American species are briefly discussed.

The following systematic account of new Lower Ordovician Brachiopods has been divided into two sections. Part I includes descriptions of a new species and variety of Resserella, two new Dalmanellas, and two new Horderleyellas, and some notes on the value of B. B. Bancroft's methods of separating Dalmanellid species and genera. In Part II two new species and a new variety of Hesperorthis, Rostricellula, and Sowerbyella respectively are recorded; an investigation of Orthis turgida McCoy shows that forms referred to this species belong either to Corineorthis, two new species of which are described, or Paurorthis.

A dyke-like mass of luxullianite type is emplaced along a line of fracture which crosses granite in a zone of pneumatolytic reddening, and is exposed in a quarry face. Extensive tourmalinization is related to post-emplacement fractures which traverse both the luxullianite and the adjacent rocks.

An account is here given of the recent discovery at Oxford of a hitherto unrecorded MS. in William Smith's handwriting, giving the list of Strata as known to him in 1797 and differing in some respects from the famous list dictated by him two years later at Bath to the Rev. B. Richardson and the Rev. Joseph Townsend, a copy of which is preserved in the Geological Society's collection. The list is reproduced here in its original form and spelling, together with a number of annotations.

Primary divisions of the lower tetrapods are believed to be expressed in the structure of the vertebrae, which represent an earlier formation embryologically than the skull. On this and other grounds the Urodeles are referred to an isolated group, the Urodelomorpha. Already in the embolomerous forms of the Carboniferous is seen the cleavage into Loxembolomeri (Batrachomorpha) and Anthrembolomeri; from the Anthrembolomeri again are derived the Diadectomorphs (Reptiliomorpha) and the Captorhinomorphs, the latter the ancestors of the Theromorphs (including Mammalia), the Archosauromorphs and the Neosauromorphs. From Triassic times onwards active evolution and the production of new types becomes progressively restricted, with the principal exception of the several Theromorph lines by which it is transmitted to the Mammalia and finally Man.
