absence of the genus Olenus. On a comparison of the paleontology 

 of the St. David's rocks with those of the continent of Europe and of 

 America which seem to occupy nearly the same horizon, we have 

 like features to a very great extent presenting themselves. 



With reference to the distribution in time of some of the earlier 

 genera of trilobites, it would appear that the genus Olenus is repre- 

 sented in Britain and Europe by twenty-two species, confined to the 

 Lingula-flags and Tremadoc rocks, and not occurring so low as the 

 Menevian group. The absence of this genus from the Menevian 

 group, and its occurrence throughout the whole of the Lingula-flags, 

 and in the Tremadoc rocks, along with the fact that, so far as pre- 

 sent observations go, no species of Paradoocides ranges higher than 

 the Menevian group, have afforded good palseontological grounds for 

 placing the line of demarcation between Upper and Lower Cambrian 

 at this spot, and for including the Menevian group in the Lower 

 Cambrian, to the bulk of which it is intimately united palaeonto- 

 logically. 



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

 Esq., E.G.S. 



The author remarked that the sandstone strata underlying the 

 Cretaceous limestones, and resting upon the granitic and schistose 

 rocks of Sinai, had been identified with the " Nubian Sandstone " 

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

 Petrsea. In the absence of palseontological 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 

 Orthis 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 JSigillaria 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., E.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 Peas 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 Gido 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 postglacial 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 postglacial winters were of
