The development of an alkali pyroxene-bearing fades of granite at the contact of the Beinn an Dubhaich granite of Skye with Durness dolomites is associated with a skarn formation involving magmatic transfer of alumina. The significance of the processes at work in this and related examples is discussed.

An impression of the actinal surface of a starfish, possibly Calliderma, has been found at Loch Aline, N.W. Argyllshire, in Cretaceous white sandstone which hitherto has yielded no fossils. Indistinct traces of the ambulacral groves are present, otherwise only the outline is clearly defined. Carbonaceous matter associated suggests the fossil may have been desiccated in dry sand. The sandstone itself is a marginal deposit with millet seed frosted quartz grains of which the perfect rounding is masked by outgrowths of authigenic quartz.

Low-lying physiographical features in the northern Sudan are associated with Lower Tertiary “lake beds”. Some undulation may have been imposed, e.g. in the Dongola bend of the Nile. There has been little vertical river erosion below the level of the lake beds in the northern Sudan, whereas in Egypt there were long successions of Tertiary sediments, uplifts, folding, and faulting. Neither late-Tertiary marine flooding nor successive regradings of the Nile in Egypt reached the Sudan. With reference to the present flood plain the summit level of some silts of Palaeolithic age rises in a striking manner from the country around Atbara (and probably a wider area) downstream into the Dongola bend, reaches a maximum (so far as known) around Wadi Haifa, and then falls again.

In the interests of accuracy and practical convenience, a detailed account is given of several instances well known to the author where vague or badly chosen place-names have given rise to uncertainty or even definite errors, in the position of geological localities, including one recent description of an important deep boring in N.E. Yorkshire. Attention is also drawn to an increasing looseness in the definition of the ancient local name of Cleveland. Trouble has also been caused by the recent invention of a new place-name, Ravenscar, which is synonymous with the ancient name, Peak (not The Peak, as often written by geologists). When an author is not himself thoroughly conversant with the place-names of his district it is recommended that some local authority, not necessarily a geologist, should be consulted.

The author emphasizes the distinction of the marine Paleocene fauna of India from that of Europe, and its resemblance to that of the West Indies (Antilles). He suggests a marine connection between West and East Indies across North Africa, south of the Mediterranean region, in basal Tertiary times, before the Americas had drifted far from Europe and Africa.

The granite of the Dicq Rock is traversed by several veins of fine grained aplogranite. These in turn are cut by a large dolerite dyke, which has been intruded into a brecciated fault zone within the granite. Three large blocks of granite occur within the dolerite; these originally formed the southern boundary of the fault. The petrography of these rocks, and the influence of the micro-breccia upon the textures found in the marginal and central part of the dolerite, are considered in detail.

The transition of Delocrinus to Paradelocrinus is demonstrated by a group of specimens collected by Mr. Allen Graffham from the lola limestone of Kansas. Description of Paradelocrinus iolaensis sp. nov. is given, and the geological range of the Permian genus Stuartwellercrinus is taken into the Pennsylvanian (Upper Carboniferous) with the presentation of Stuartwellercrinus argentinei sp. nov. from the Wyandotte limestone of Kansas.
