The Rev. "W. S. Symonds had, in visiting the spot, been much struck by the rocks, 

 at that time termed Syenite, which he believed might be an extension of those on the 

 Caernarvonshire peninsula, and which he thought supported the whole series of the 

 Cambrian rocks, so that they might after all be the Laurentian, the same as those of 

 Sutherlandshire and Assynt. If this were the case the nomenclature of the Geological 

 Survey would have to be altered, and the rocks of Pistyl and Holyhead no longer 

 termed metamorphosed Cambrian rocks, but Laurentian. 



Mr. Hicks, in reply, stated that the quartziferous breccias forming the central ridge 

 contained so many rolled pebbles, and were, moreovei', in places so distinctly bedded, 

 that there could be no doubt of their being sedimentary. Other beds, described as 

 Greenstone in the maps of the Geological Survey, were also distinctly laminated. 

 The non-occurrence of fossils in the more sandy beds he attributed to their having 

 been deposited in very shallow water. The fossils occurred principally in fine-grained 

 beds of a flaggy nature. 



2. "On the Age of the Nubiaii Sandstone." By Ealph Tate, 

 Esq., F.G.S. 



The author remarked that the sandstone strata underlying the 

 Cretaceous limestones, and resting upon the granitic and schistose 

 I'ocks of Sinai, had been identified with the " Nubian Sandstone" 

 described by Eussegger as occurring in Egypt, Nubia, and Arabia 

 Petrsea. In the absence of paleeontological evidence, this sandstone 

 has been referred to the Mesozoic group, having been regarded by 

 Eussegger as Lower Cretaceous, and by Mr. Bauerman and Figari- 

 Bey as Triassic, the latter considering an intercalated limestone-bed 

 to be the equivalent of the Muschelkalk. The author has detected 

 Ortliis Michelini in a block of this limestone from Wady-Nasb, which 

 leads him to refer it to the Carboniferous epoch, as had already 

 been done by the late Mr. Salter from his interpretation of certain 

 encrinite-stems obtained from it. The author mentioned other fossils 

 obtained from this limestone, and also referred to species of Lepido- 

 dendron and Sigillaria derived from the sandstone of the same 

 locality. He regarded the Adigrat Sandstone of Mr. Blanford as 

 identical with the Nubian Sandstone. 



3. "On the Discovery of the Glutton (Gulo luscus) in Britain." 

 By W. Boyd Dawkins, Esq., M.A., E.E.S., F.G.S. 



The author in this paper described a lower jaw of the Glutton, 

 which had been obtained by Messrs. Hughes and Heaton from a 

 cave at Plas Heaton, where it was associated with remains of the 

 Wolf, Bison, Eeindeer, Horse, and Cave-Bear. He remarked that 

 he could detect no specific difference between the Gulo spelceus, 

 Goldfuss, from Germany, and the living Gulo luscus, except that the 

 fossil Carnivore was larger than the living, probably from the com- 

 parative leniency of the competition for life in post-Glacial times. 

 He referred to the distribution of the Glutton in a fossil state, and 

 argued that its association with the Eeindeer, the Marmot, and the 

 Musk-sheep, would imply that the post-Glacial winters were of arctic 

 severity, whilst the presence of remains of the Hippopotamus, 

 associated with the same group of animals, would indicate a hot 

 summer, such as prevails on the lower Yolga. 



Discussion. — Mr. Hughes indicated the exact position in which the jaw of the 

 Glutton was found, but pointed out that, owing to the excavations of keepers, badgers, 

 rabbits, &c., the earth was so much disturbed in that part that it was impossible to be
