LOWER LIAS. 267 



exposed on the 'banks of the Severn at Ehiiore and Wainlode, 

 and in the railway-cutting at Lassington ; the zone of A. 

 angiilatiis has been determined at Down Hatherly ; the zone 

 of A. Bucldandi may be studied at Fretherne and Purton-on- 

 Severn ; that of A. Turncri at Purton ; and that of A. obtusus at 

 Standish. The zone of A. raricostatus has been well exposed at 

 the brick-pit at Marie Hill, near Cheltenham ; it there contains the 

 Hippopodmm-hed, with H. pojiderosum and Cardmi'a Listen. The 

 zones of A. Jainesoni and A. ibex have also been exposed in 

 brickyards near Cheltenham.^ The term Belemnite-beds has 

 been used by Prof. R. Tate for the clayey beds of the Lower 

 Lias above the zone of Ammotiiles Bucklandi; these he has also 

 termed the zone of Belenuiitcs acutus. 



In Worcestershire the Lower Lias is developed at Pershore, 

 Evesham, and other localities." 



Near Banbury the zones of Ammonites Janusoni, A. Henhyi zxiA 

 A. capricornus have been observed by Mr. T. Beesley and Mr. E. A. 

 Walford. From the zone of A. Henleyi ■m.z.wj fossils, including a 

 number of Foraminifera, have been obtained. The beds consist 

 of dark-blue shaly marls, with occasional septaria, and with a thin 

 bed of hard grey shelly limestone, known as Banbury Marble.^ 

 The zone of A. Henley i is shown in brickyards east of Banbury, 

 and it occurs below the zone of A. capricornus, which is exposed 

 south of the town. The zone of A. ibex occurs rather as a sub- 

 zone, between the beds with A. Jamesoni and A. Henley i. The 

 Banbury Sandstone, with Beleninites pencillatus, the Edgehill Sand- 

 stone, and the Downcliff sandy marl with Ammo?iites annatiis, 

 belong to the Lias of this district. 



The zone of Ammonites Jamesoni is well developed at Fenny 

 Compton, south-east of Warwick ; and with it Mr. T. Beesley 

 includes the zones of ^. ibex and A. Henleyi at the top, and that 

 oi A. armaius ■3,\.\\xQ-\>o\\.oxa..^ In Warwickshire the thickness of 

 the Lower Lias is estimated at upwards of 600 feet. The zone 

 of A. angidatus has been noted at Harbury, near Warwick. 

 The beds may be seen also at Inkberrow, and outliers with 

 underlying Rhsetic beds occur at Copt Heath (Knowle), and 

 Wootton Wawen.* The lower beds are well shown at Wilmcote 

 and Binton, near Stratford-on-Avon, where they have been largely 

 quarried." 



In Leicestershire the Lower Lias attains a thickness of 520 feet ; 

 the upper portion consisting chiefly of clays, and the lower 20 feet
