172 MR. L. RICHARDSON OX THE [vol. lxxiV. 



what I regard as their lower portion, is a very interesting Sponge- 

 Bed, similar in appearance to that exposed in the Peas-Hill Quarry. 

 Shipton Gorge (Dorset). The Sponge-Bed is rich in rnicrozoa, 

 and Mr. Charles Upton — on the evidence that the}' supply — would 

 correlate the deposit with the Upper Coral-Bed (early truellei) of 

 Dundry Hill, Midford, and the Cotteswolds. 



The Zigzag Bed has been observed at North Perrott and 

 Haselbury Mill. 



The Scroti — tbe horizon of Aitlacotliyris cucullata S. Buckman 

 — was apparently observed by J. F. Walker in a quarry near 

 Misterton Church. 



Fuller's- Earth clay succeeds the Scrofr".
