The cephalopods and stromatoporoid collected from Akpatok Island, Ungava Bay, N.W.T., in 1931, by Cox, are described by Foerste in this communication as follows:—

Endoceras coxi sp. nov., Endoceras sp. (resembling E. coxi), Endoceras akpatokense Foerste, Endoceras two spp., Shamattawaceras cf. ascoceroides Foerste and Savage, Orthoceras ungavense Foerste, Spyroceras sp. (resembling S. balteatum (Bill.) in some respects), Spyroceras cf. aquilonare Troedsson), Spyroceras wordiei Foerste, Spyroceras two spp., Huronia septata Parks, Westonoceras sp., and Beatricea undulata Billings.

Tentative correlations of the Akpatok limestones with other areas are drawn from this material. The greater part of the lime-stones appear to correlate with the Red River formation of Manitoba. The lowest horizons, containing Westonoceras, apparently correspond to part of the Nelson River formation of the Hudson Bay region; the intermediate horizon, with Shamattawaceras and Huronia, apparently to the Shamattawa formation of the same locality; while the horizon with Beatricea (650 feet above sea-level) is of Richmond age. The extent to which the remainder of the fauna, as yet identified, agrees with this is reviewed.

“Geologists should think to scale”; so Professor Daly has urged in one of his illuminating writings. Returning from a visit to the Rift Valley country, I realize that in the past I have failed to picture these remarkable valleys to scale. Perhaps I received a wrong impression in the beginning from the rather extravagant language used by some of the earlier writers: “a yawning abyss,” says one; “walls as steep and abrupt as those of a grave,” says another; “in many parts the walls are so precipitous that not even the most expert of cragsmen could scale them,” says a third. Then the well-known drawings of the arch and the sunken keystone, and the rival diagram of the great ramps with a depressed block between them—although I knew that these were only diagrams, not scale drawings, I fear they played their part in perpetuating the early, extravagant impression. So it came to pass that when I stood at last between the walls of the great depression, the glow of satisfaction brought on by the realization of a long-cherished wish was chilled by a rather childish disappointment. Mine was not the case of the man who was shown a giraffe and said “I don't believe it!;”; I believed in the giraffe, but it didn't come up to expectation!

The term “charnockite series” is now commonly in use for a group of genetically related rocks ranging from ultrabasic to acid members having the chemical and mineralogical features of the rock suite of the type area of Madras (Holland, 1893, 1900). The acid member “charnockite” is defined by Holland (1926) as “essentially a hypersthene granite…composed of hypersthene, microcline, quartz, and iron ores…”.

Although fossil plants of Jurassic age are known from an area of about a square mile at Tabbova and Miocene marine invertebrates have been recorded from several coastal localities, there is no authentic record of vertebrate fossils from Ceylon. It had hitherto been suspected that local conditions were not conducive to the preservation of bones, but it now transpires that there are such fossils which are as interesting as those of India or Burma.

In February, 1932, the British Association Committee appointed to examine and report upon petrographic classification and nomenclature issued a questionnaire in the GEOLOGICAL MAGAZINE and in Science, in order to ascertain what measure of agreement, if any, exists among petrologists as to the principles upon which a rational system might be established.
