rare. These pebbles agree precisely in lithological character with 

 the Llandovery sandstones seen in place at the Lower Lickey and 

 Great Barr, and the fossils mentioned have been found at the 

 Lower Lickey. 



(5) WooLHOPE Limestone. — A. piece of bluish-grey limestone from 

 Eand C^ of the Warley area contains a Woolhope fossil, Stropho- 

 mena arenacea, and lithologically resembles part of the Lower Lickey 

 Woolhope Limestone (5 miles away). In Eand C^ of the Bowhills- 

 Enville district a few pebbles occur of a similar bluish-grey lime- 

 stone, one of which contains that fossil of wide range StropTiomena 

 rhomboid alis, and another contains Euomphalus sculptus. There are 

 moreover in the Bowhills-Enville, Stour Valley, and Warley-Barr 

 districts a few coarsely crystalline yellow limestone-pebbles, one 

 of which (from Bowhills) again contains StropTiomena rhomhoidalis. 

 Part of the "Woolhope Limestone in place at the Lower Lickey is a 

 precisely similar, coarsely crystalline, yellow limestone. Pebbles of 

 Woolhope Limestone are, however, rare in these conglomerates. 



(6) Wenlock Limestone. — Two distinct types of Wenlock Lime- 

 stone occur in these conglomerates : (a) the dolomitic limestones ; 

 (6) the non-dolomitic limestones. 



(a) The Dolomitic Limestones. — Some of these limestone- 

 pebbles are firm, compact, and finely crystalline, and in colour red, 

 reddish- brown, pink, or yellow. Others are coarsely crystalline, 

 and are usually red or pink. 



In the coarsely crystalline varieties the amount of red coloration 

 varies so considerably, that sometimes, unless closely examined, 

 they may be mistaken for the ordinary grey Wenlock Limestone. 



These dolomitic limestones contain (among other fossils) StricHan- 

 dinia lirata, Orthis Bouchardii, Rhynchonella cuneata, Glassia com- 

 ■pressa, and Pterinea planidata. 



The dolomitic limestones, as Murchison observed, occur in greatest 

 abundance in Bands B^ & C^ in the Bowhills district, in C in 

 the Enville district, and in the calcareous band of the Warshill 

 area. In these bands in the South-east Shropshire region the 

 dolomitic limestones constitute at least half of the pebbles, while 

 in the Stour Yalley and Warley-Barr districts they rarely amount 

 to one-tenth. 



Dolomitic limestones of the same age as, and of rock -types strikingly 

 similar to those of these pebbles in the calcareous conglomerates, crop 

 out at Abberley Hall,^ and in many parts of the Abberley-Malvern- 

 May Hill range. Phillips called them the Magnesiferous, and on 

 other pages the Dolomitic Wenlock Limestones. Mr. T, H. Waller 

 kindly analysed for me a specimen found in situ at Woodbury Hill, 

 and it contains 3*12 per cent, of magnesia. He analysed another 

 from farther south, at Collins Green, between Abberley and Malvern, 

 which contained 18'31 per cent, of magnesia ; while a third from 



^ The exposure referred to is the broad band marked, on the Geol. Surv. 

 maps, eyidently by a clerical error, as Aymestry Limestone. In the Memoirs 

 it is correctly designated Wenlock.
