MISS G. L. ELLES AND MISS I. L. SLATEE ON THE [May 1906, 



cliff-face ; they dip 20° northward, and, as usual, Conehidium (Penta- 

 merus) Knightii is the characteristic fossil, associated with Stropho- 

 mena euglyjoha, Wilsonia Wilsoni, Atrypa reticularis, and other forms. 

 These beds are also seen on the southern bank south-east of the 

 bridge. In the immediate neighbourhood of the bridge they are 

 succeeded by the Mocktree Shales (B), crowded with Dayianavicula. 

 These are seen to bend round quickly at the edge of the syncline, and 

 dip eastward (downstream) at a low angle. These Mocktree Shales 

 extend as far as the Hay Mill on the southern bank, but for a 

 slightly-shorter distance on the north side, where a steeply-rising 

 cliff brings on the massive Bhynchonella-Beds (C), down to water- 

 level. Beyond the Hay Mill, these Rhynchonella-Beds form cliffs 

 on both sides of the river for half a mile, where they are succeeded 

 by the Chonetes-Beds (D). At the Weirs a fault runs obliquely 

 across the stream, causing a repetition of the Rhynchonella-Beds 

 on the north side ; they extend thence to Downton-Castle Bridge 

 at the base of the high cliff, the upper portion of which is formed 

 of the Chonetes-Beds.

On the south side of the river the Chonetes-Beds form the base 

 of the cliff, which is capped by the Downton-Castle Sandstones (E), 

 and close to Downton-Castle Bridge the Spirifera-elevata Beds (D b) 

 succeed the Lower Chonetes-Beds (D a), and are surmounted at road- 

 level by the Ludlow Bone-Bed (D c). The Spirifem-elevata Beds 

 are about 12 feet thick at this locality, and contain a band swarming 

 with Crania implicata.
