A brief outline description of the main subdivisions is first given, 

 as they appear when followed from Lndlow southward to Overton, 

 eastward to Caynham Camp, westward to Downton-on-tlie-Rock, 

 and northward to Bromfield, and also near Onibur}' and Norton. 

 The main tectonic features of the district appear to be due to the 

 superposition of Armorican movements in rocks with a Caledonian 

 trend, held by some rigid mass to the north, presumably the 

 Longmj'nd massif. A detailed description is then given of the 

 succession, as seen at the following localities: Eiver Teme, Wigniore 

 Road, Beerhouse Rank, Caynham inlier, the Teme and north-east 

 of the Castle at Downton, Downton Castle inlier, Mocktree, and 

 near Onibnry on the Craven Arms Tioad, the Onibury Norton Lane, 

 and at Norton. 'J'he paper closes with a detailed list of fossils 

 obtained b^^ the authoresses, supplemented by the collection in th& 

 Ludlow Museum. 



2. " The Carboniferous Rocks at Rush (County Dublin)." By 

 Charles Alfred Matley, D.Sc, F.G.S. With an Account of th& 

 Faunal Succession and Correlation. By Arthur Vaughan, B.A., 

 D.Sc, F.G.S. 



Rocks of the Carboniferous Limestone Series are exposed along 

 5 miles of coast near Rush, Loughshinny, and Skerries, in county 

 Dublin. The present paper deals only with the beds near Rush, iu 

 the southern portion of this tract, where about 2,500 feet of the 

 series are exposed, without allowing for gaps in the succession. The 

 upward sequence is (on the whole) from south to north, and the 

 range is from the Upper ZapJireiUis to the Upper Dihiuwphyllnm Zone. 



The Rush Slates are the lowest beds, 1,380 feet thick, but 

 their base is not visible. They consist of black and dark-grey, well- 

 cleaved argillaceous, and less perfectly cleaved calcareous, slates ; 

 and they contain bands and nodules of limestone. The peculiar 

 outcrop of some of the limestone bands is described, and instances 

 of cataclastic structure are noticed. The characteristic fossil is 

 Zaplirentis aff. FhilUpsii. 



The Rush Conglomerate Group succeeds the Rush Slates, after 

 a short interval of passage-beds. It is oOO feet thick, and consists 

 of well-bedded alternations of conglomeratic, pebbly, and sandy 

 limestones, with shales and calcareous flaggy beds. Ordoviciaa
