rEOCEEBINGS OF XnR OrOLOGICAL SOCIETY. 9 



to 30 species, probably mostly new. Of the 90 named species, 19 

 passed from Lower Devonian into Carboniferous, 12 from Lower 

 ])evoniiui to Pilton ; these slioiild not be t'lken into consideration. 

 Of the remaining 51), 23 pass up into the Carboniferous, whilst only 

 12 pass down into the Ilfracombe Beds. The species characteristic of 

 Ikggy and Pilton lieds are 24, of which 10 are recorded from Upper- 

 Devonian Peds of other areas. In correlating these beds with those 

 of Continental regions, similar results are obtained. The Baggy 

 Beds are certainly on the horizon of the Upper-Devonian Beds of 

 Belgium. He believed, therefore, that the palajontological evidence 

 was clearly in favour of the old succession. 



Mr. Makr saw difficulties in sup})osing that the differences between 

 the junction of the Baggy Beds and the Morte Slates, and that of the 

 beds at Combe Martin with the Hangman Grits, could be accounted 

 for by the faulting-out of some of the beds near Combe Martin. As 

 the result of a hasty inspection, he was rather inclined to favour the 

 notion of an upward passage from the Ilfracombe Beds into the Morte 

 Slates. If he had understood the paper aright, the Author would place 

 the Pilton Beds, with their undoubted Carboniferous affinities, under 

 the Great Devon Limestone ; this appeared to him to be almost a 

 return to the doctrine of Colonies, with which he could not agree, 

 and it was entirely contrary to the conclusions of both Prof. Jukes 

 and Mr. Etheridge. 



Prof. Seeley had made several traverses of North Devon in 

 search of faults when Prof. Jukes's views engrossed attention, but 

 had seen no trace of the faults which were necessary to Prof. Jukes's 

 theory. He hoped, when Dr. Hicks's views were published, he 

 would insert localities where the faults can be seen and traced, in 

 order that those Avho differed from his views might know exactly 

 where to look. He confirmed Mr. Boberts's conclusions concerning 

 the Carboniferous facies of the Upper-Devonian fauna of the Baggy 

 Beds. 



Mr. H. B. "Woodward had elicited a letter containing Mr. Ussher's 

 views. The latter considered that Dr. Hicks had not weighed the 

 evidence contained in the literature of the North-Devon Rocks, where 

 it was absolutely demonstrated that the three grit series were quite 

 distinct. The Morte Slates were in their true position, as shown in 

 AVest Somerset and near Dulverton. The Cuculla3a-zone did not come 

 in the Lower series of slates. The development of grits in the North- 

 Devon area was a natural consequence of the geographical conditions 

 in that area. He believed Dr. Hicks's thrust-planes were imaginary. 

 The speaker remarked, on his own behalf, that it was not demon- 

 strated that the three sandstone bands were all different, and if the 

 Poreland sandstones were the same as the Hangmans, we should 

 only have two sandstones to deal with. Mr. Ussher had shown 

 that the Cockington and "Warberry grits were the same. He 

 believed the Torquay coral-limestones must come in below the 

 Pilton Beds ; but the higher beds of the South-Devon limestone, of 

 Chudleigh and Pctherwin, yielded some Carboniferous species, and 

 these beds were overlain by strata yielding Posidonomya and Gonia-
