236 Itejjorfs and Proceedings — Geological Society of London. 



The author gives a brief description of the geology of four 

 localities, within a comparatively short distance from Johannesburg, 

 from which several fossil plants have recently been obtained. He 

 considers the plant-bearing beds to belong to the Lower Stormberg 

 Series of Dunn, and to the horizon known as the Molteno Beds. 

 The most important locality described in these notes is that of 

 Vereeniging, 30 miles south of Johannesburg, where the author 

 found several specimens of Sigillaria associated with Glossopteris 

 and other plants in iron-stained sandstones. The significance of 

 this discovery of Sigillaria is briefly discussed. The sevei'al species 

 of plants have been described by Mr. A. C. Seward in a paper 

 recently sent to the Society. 



II.— April 7, 1897.— Dr. Henry Hicks, F.E.S., the President,

1. " On the Morte Slates and Associated Beds in North Devon 

 and West Somerset.— Part II." By Henry Hicks, M.D., F.E.S., 

 P.G.S. With Descriptions of the Fossils by the Eev. G. F. Whid- 

 borne, M.A., F.G.S. 



In the first part of this paper, read by the author before the 

 Society in February, 1896, he described the Morte Slates as they 

 occur in North Devon, and the fossils found in them. In this, the 

 second part, he refers mainly to the rocks classified as Morte Slates 

 in West Somerset He shows that the latter difi'er in some 

 important characters from those in North Devon, and have an 

 entirely distinct fauna. The fossils obtained from North Devon 

 show that there the beds must in the main be classed with the 

 Silurian rocks; but in West Somerset, so far as discoveries have 

 yet been made, the fossils indicate that they should be classed 

 with Lower Devonian rocks. The author's contention that the 

 Morte Slates which extend through the centre of North Devon and 

 West Somerset from Morte Point to the north of Wiveliscombe, 

 a length of about 40 miles, are the oldest rocks in the area and form 

 an axis with newer rocks lying to the north and to the south, 

 is therefore fully proved by stratigraphical and palseontological 

 evidence. The fossils are carefully described by Mr. Whidborne, 

 and he shows that there are numerous forms in common between 

 them and those considered to be characteristic of the Lower 

 Devonian rocks in the continent of Europe and in America. 



The President then resumed the Cbair. 



2. "The Glacio-Marine Drift of the Vale of Clwyd." By 

 T. Mellard Keade, Esq., C.E., F.G.S. 



The local drift of the higher parts of the Vale of Clwyd is 

 replaced by marine drift towards the mouth ; and it is the object 

 of this paper to give the results of a detailed examination of these 

 marine drifts, rather than to explain the phenomena. The first 

 part of the paper gives the results of an examination of the Boulder- 

 clay from Craig, west of Llandulas, to the Vale of Clwyd, south-east 

 of Abe) erele.
