height. The succeeding Spirifera-elevata Beds (D 6) are about 12 feet 

 thick ; but the Ludlow Bone-Bed (D c) appears to be overgrown 

 by vegetation wherever the cliff is accessible : its position, however, 

 can be approximately determined, since the Spirifera-elevata Beds are 

 found about 40 feet above water-level, while the lowest members of 

 the Downton-Castle Sandstones (E) are seen a few feet above.

On the other side of the river the succession is clearer : the 

 €honetes-'Beds again form the base of the cliff both east and west of 

 Forge Bridge, dipping north-westward ; and, owing to the unsym- 

 metrical nature of the fold, the Ludlow Bone-Bed is visible at a 

 lower level, being seen in the road leading down to the bridge, along 

 a track leading to Forge Rough, and again farther to the north- 

 east, close to a cottage by the Old Millrace-weir. 



Teme side Group. — At all these localities the Platyschisma- 

 Bed (E b) is found, in its usual position, with the intervening 3 feet 

 of mottled sandstone between it and the Ludlow Bone-Bed. In 

 the road-section it is slightly 'bony' in character; but at the Cottage 

 it has taken on all the characteristics of a bone-bed, and so closely 

 resembles the Ludlow Bone-Bed that it can only be distinguished 

 by the presence of Fl-atyschisma, which still occurs abundantly and 

 has never been found by us at the lower horizon. From the Cottage 

 this Platyscliisma Bone-Bed ( = Down ton Bone-Bed) strikes down 

 towards the River Teme, and is seen at river-level about 100 yards 

 farther east. The beds immediately above it are the massive yellow 

 sandstones with Lingula minima (E c). The higher members of the 

 Downton-Castle Sandstones form the remainder of the cliff on the 

 north side of the river, but are only well exposed in the quarries on 

 either side of the road leading to the bridge, where the highest 

 sandstones (E e) are seen. The entire thickness of these sandstones 

 does not seem to exceed 35 feet at this locality, although there is a 

 little variation from place to place. The beds gradually bend round
