Prof. Huxley on some remains of large Dinosaurian Reptiles. 475 



point of size to its near allies, the Megalosaurus and the Iguanodon. 

 To the former of these it possesses the closest affinity, but differs in 

 the proportional size and form of its trochanters, and in its much 

 heavier proportions ; and the author proposes for it the name Euske- 

 losaurus 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 Stormberg rocks was stated 

 to be by no means decisive of their geological relations, as Dinosau- 

 rian reptiles lived throughout the Mesozoic period, and may have 

 existed during the Permian ; but it is interesting to observe that the 

 Stormberg rocks conformably overlie the Karoo beds, which have 

 yielded the Dicynodonts and so many other remarkable Reptiles and 

 Labyrinthodonts. 



2. "Additional Notes on the grouping of the rocks of North 

 Devon and West Somerset." By J. Beete Jukes, Esq., M.A., 

 F.R.S., F.G.S. 



Commencing with the country around Wiveliscombe, 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. Simi- 

 larly, after examining the neighbourhood of Combe Martin, he pro- 

 ceeded 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 principal con- 

 clusions 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 ; b, The Porlock, 

 Minehead, and Dunster area ; and c, The Morte Bay and Wivelis- 

 combe 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 

 contemporaneous with the Coal-measures, the Carboniferous Lime- 

 stone, 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 under- 

 neath a great thickness of Carboniferous Slate. Mr. Jukes had also 

 been able to construct a geological sketch map of North Devon in 

 conformity with his views; and the paper concluded with a few 

 notes explanatory of it.
