is impossible to say how far the Rhcetic series extends east 

 and west in this direction between Eatington and Kineton, 

 two miles south of Wellesbourne, where they are perhaps 

 twenty feet thick or more, or to estimate the entire thick- 

 ness; but they are known, by boring, to occur beneath the 

 insect and inferior beds, firestones, &c. at Wilmcote and in 

 situ at Binton and again at Copt Heath, near Knowle,* 

 their furthest northern limit in this county, where a thin 

 yellow sandstone abounds in PuUastra arenicola, and the 

 Avicula-contora shales come in. These are well developed 

 and very fossiliferous at Brown's wood, near Wootton 

 Wawen ; so that they occupy a larger area in this part of 

 Warwickshire than has been usually supposed, though 

 sections are rarely exposed, and fossils by no means abun- 

 dant. In the neighbourhood of Eatington very few charac- 

 teristic fossils have been found. 



These sections afford the largest and most illustrative 

 exposiu-e of the Rhcetics in Warwickshire, and, in all 

 probability, they underlie the lowest beds of Lias in its 

 range through the area occupied by that formation. From 

 Stratford to Upper Eatington the line runs nearly from 

 N.W. to S.E., from Eatington to Kineton S.E. to the E. 

 byN. 



The Lima and Ammonites-angulatus beds f may be traced 

 along the line from thence to Kineton Station, in a horizon- 

 tal position. At the back of the station they begin to curve 

 slightly, and a fault here runs obliquely and affects the 

 strata on each side of a deep cutting in an easterly direction, 



* This sandstone may be seen in situ in places on the hank of the canal, and 

 though not visible, the black shales no doubt underlie it, as traces of these can ba 

 observed in an artiflcial bank, the greater part of which must have been thrown up 

 when the canal was dug. 



t It may be questioned whether any clear distinction can be made between tho- 

 Lima or Bucklandi zone, and the Angulatus zone in this section.
