ELEVEN out of twelve samples of East Anglian Uppermost Pliocene and Pleistocene crag, clays, boulder clays, brickearths, and sands yielded foraminiferal faunas which are partly derived from older deposits. One hundred and thirty-one species are recorded, with their distribution in the samples and frequency; thirty-nine are indigenous, one derived from the Lower Pliocene, fifty-eight derived from the Chalk, eighteen derived from the Jurassic, and sixteen of doubtful age. Twenty-seven forms, largely indigenous, are figured; none are new. Notes are given on a few of the species. A short discussion, based solely on the foraminifera, is given of the climatic conditions under which the various deposits were laid down. The Weybourn Crag fauna points to cold conditions, and that of the Chillesford Beds sample to a climate rather less cold. From conflicting evidence and the derived nature of the faunas no very precise conclusions are possible in the case of the Pleistocene deposits, since the faunas contain a sprinkling of species characteristic of temperate or even warm conditions in addition to typically boreal forms.

IN the course of several journeys between Masindi and Butiaba, and one from Butiaba to Hoima (via Waki Camp), specimens of the various gneisses were collected from roadside exposures. Thin sections of these were subsequently studied by the writer in England with the result that they were found to yield evidence of tectonic significance. In addition, the writer has, during the last three years, examined petrographically a large number of other rocks from those parts of Uganda bordering the Lake Albert Depression. In particular he has made a special study of the Charnockite Series, which are widely spread over the northern half of the Protectorate, with the result that it has been possible to observe the effects of the rift valley movements on these rocks in the regions adjacent to Lake Albert. It is hoped to publish a petrological and geochemical study of the Charnockite Series of Uganda in the near future. In the following pages it is proposed in Part I to present petrological evidence from the basement rocks of various districts in the hinterland of the Lake Albert scarps and then in Part II to point out the tectonic significance of this evidence in the light of the various theories of rift valley formation. In Part III the relation between the petrological characters of the volcanic rocks and the rift valley tectonics will be briefly reviewed. In the case of the basement rocks the remarks will be confined to the Lake Albert Depression, but in the case of the volcanic rocks the discussion will extend also to Lakes George and Edward and the Birunga volcanic field.

AN interesting collection of Tertiary fossils has recently been sent me for determination by Mr. C. P. Manglis, Manager of the Mitsero mines in Cyprus, who has collected them from the neighbourhood of these mines. Mitsero village stands near the head of a valley running down the north side of the Troodos mountains to the plains of Morphou and is described by Messrs. Cullis and Edge (1, p. 38) as standing on volcanic rocks close to the junction of the pillow-lavas with the overlying marls and limestones, while “ behind it is a bold sedimentary escarpment breached by the valley just mentioned and culminating in Koroni Mountain (2,140 feet), 1½ miles to the westnorth-west ”. The Koronia Limestone, the outcrop of which on the Evrykou road the author visited in 1929 (2, p. 443), occupies the top of the escarpment, as shown on a map sent to me by Mr. Manglis of the immediate district (scale, 1: 10,000) from the village of Kato Moni on the north-west to the village of Mitsero on the south-east. The position and age of the Koronia Limestone have been uncertain owing to the lack of definite fossil evidence, though the author (2a, p. 251) was inclined to put it in the Miocene rather than the Pliocene on the strength of a species of Cerithium which he discovered in it. The majority of the fossils in Mr. Manglis’s collection come from this limestone and provide ample evidence of its Miocene age.

DURING 1931 the writer had occasion to make several journeys across the western part of the coastal belt of British Somaliland, southward from Zeilah to Buramo, near the Abyssinian frontier.

IN this paper it is proposed to give a brief account of the petrography of the Kainozoic igneous rocks collected by Mr. J. M. Wordie during the Cambridge Expedition to East Greenland led by him in 1926. A small collection of alkaline igneous rocks, but of less certain age, was also made from Cape Parry, and is briefly dealt with in this paper. As Mr. Wordie has written a short note on the geology of the Tertiary igneous rocks in his geographical paper, and as Dr. H. G. Backlund intends shortly to publish a much more comprehensive account of Tertiary igneous activity and rocks in East Greenland than is possible on the basis of the materials collected by the Cambridge Expedition, this paper aims only at making a brief record of the petrographical characters of the collection, and especially at recording three new chemical analyses, two of the Kainozoic basalts, and one of a riebeckitetrachyte from the Cape Parry alkaline complex. For the most recent account of the general geology of East Greenland, and for a connected summary of the Kainozoic igneous rocks collected by other expeditions, the reader is referred to memoirs by L. Koch and H. G. Backlund.
