form of its trochanters, and in its much heavier proportions ; and 

 the author proposes for it the name Eus/celosaurus Browni. A 

 portion of the distal end of a femur indicating another genus of 

 large-sized Dinosaurian reptiles was also described, the characters 

 yielded being sufficient to prove that it belongs to another genus 

 than Euskelosaurus. The discovery of these remains in the Storm- 

 berg rocks was stated to be by no means decisive of their geological 

 relations, as Dinosaurian reptiles lived throughout the Mesozoic 

 period, and may have existed during the Permian ; but it is interest- 

 ing to observe that the Stormberg rocks conformably overlie the 

 Karoo beds, which have yielded the Dicynodonts, and so many other 

 remarkable reptiles and Labyrinthodonts. 



Additional Notes on the Grouping of the Rocks op North 

 Devon and West Somerset. By J. Beete Jukes, Esq., MA., F.R.S., 

 F.G.S. — Commencing with the country around Wiveliscomb, near 

 which place Sir H. De la Beche had indicated an east and west fault 

 of small extension on the maps of the Geological Survey, Mr. Jukes 

 described the rocks of the district reaching from that place north- 

 west to the Brendon Hills, and westwards to Dulverton, including 

 the valley of the. Tone, more to the south. .From Dulverton he 

 examined the country towards Simonsbath, and then, proceeding to 

 Barnstaple, made traverses from that place to Challacombe and to 

 Bittadon. Similarly, after examining the neighbourhood of Combe 

 Martin, he proceeded along the north coast in an easterly direction, 

 through Countesbury, Porlock, and Dunster, and across the Williton 

 valley to the Quantock Hills. The observations made during these 

 several journeys were given in detail by the author ; and the prin- 

 cipal conclusions at which he had arrived in consequence were stated 

 to be the following : — (1) There are three areas of old red sandstone 

 in this region, namely, a, the Quantock Hills ; o, the Porlock, Mine- 

 head, and Dunster area ; and c, the Morte Bay and Wiveliscombe 

 ridge. (2) Each of these masses of old red sandstone dips under a 

 great mass of carboniferous slate. (3) The coal-measures, the 

 carboniferous slate, and the old red sandstone of Devon are con- 

 temporaneous with the coal-measures, the carboniferous limestone, 

 and the old red sandstone to the north of the Bristol Channel. 

 (4) That if the great fault which the author believes to exist be 

 proved to be absent, his other conclusions will not be altogether 

 vitiated, for the red rocks of Porlock and Dunster may then be 

 taken as the top of the true old red sandstone lying underneath a 

 great thickness of carboniferous slate. 



ROYAL MICROSCOPICAL SOCIETY— Nov. 14. 



A letter was read containing Her Majesty's command that this 

 society, which recently obtained a charter of incorporation, shall be 

 a "Royal Society." Fellows will use the letters F.R.M.S. The 

 bye-laws of the society were revised, and one of them referring to 

 the term of office of the president was suspended with a view to 

 the re-election of Mr. Glaisher, whose term of office would normally 

 expire in February.
