72 MK. L. EICHAEBSON ON THE EHJ3TIC OF [Feb. I9II, 



Grubble-Hill outlier. — Portions of the Red Marls, Tea- 

 green Marls, Pteria-contorta Shales (with a Pecten Limestone, 1 to 3 

 inches thick, and Volsetta sp. indet., Saurichthys [tooth], and fish- 

 scales), and the pale marls of the Cotham Beds are to be observed 

 in the sides of the lane which climbs the western flank of the 

 outlier ; while in a quarry at the eastern end are seen about 4 feet 

 of Langport Beds overlain by certain Lower Liassic deposits, which 

 correspond — so far as the upward succession goes — bed for bed with 

 the equivalent rocks in the quarries on Breach Hill, and between 

 Cuckoo's Nest and Nempnet Farm. 



Ban well outlier. — There are no exposures of the Rhaetic on 

 this outlier, but the Planorbis Beds are finely displayed in a quarry 

 near Knightcote.

Discussion. 



Mr. S. S. Stanley said he thought that the point to be decided 

 was whether the Sully Beds were conformable to the superimposed 

 Rhaetic strata or to the Upper Keuper below them. So far as his 

 own observations went in the Southam, Ufton, Harbury, and 

 Chesterton parishes, where the beds occurred at the surface, and 

 also in the Stratford-on-Avon vicinity, they were conformable to 

 the Rhaetic. With regard to the Stratford neighbourhood, the 

 speaker thought that there the beds showed an estuarine origin, 

 as fossil insects were fairly abundant. Neither the late Rev. P. 

 B. Brodie nor he himself had ever found anything like an insect in 

 the Harbury neighbourhood ; and so it might perhaps be inferred 

 that there the beds were deposited at a greater distance from 

 any coast. Between Harbury and Whitnash, x on the Roman Fosse 

 Road, two or three very interesting faults were noticeable. In no 

 case could the Sully Beds be found conformable to the New Red 

 Sandstone, so far as the knowledge of the speaker went. The 

 localities to which he referred were about 4 miles from Leamington. 

 The cutting on the Great Western Railway, as that line approached 

 Harbury from Leamington, commenced on the west in the New 

 Red Series, and passed through the Rhaetic into the Lower Lias : 

 the contour and the dip made almost a right angle.
