348 On the Upper Formations of the New Red Sandstone Si/stem. 



from the sandstone of Kenilworth, and the only remarkable circumstance con- 

 nected with this quarry, is the discovery of a fossil jaw, represented at Plate 

 XXVIII., fig. 5. The teeth of this jaw are very irregular both in form and 

 position, and appear to have lost much of their destructive character by tri- 

 turation. The teeth are not inserted in alveoli, but are united with the max- 

 illary bone like the teeth of fishes. 



This specimen, the only example known of an animal relic in this part of 

 the New Red Sandstone of central England, is deposited in the Warwick 

 Museum. 



At the railway station near Coventry, the cuttings have laid bare the upper 

 or light-coloured beds of variegated sandstone, spotted with manganese, dip- 

 ping to the E.S.E., and covered by the red marl or Keuper, which, on ihe 

 line to London, is seen to graduate into and pass under the lias. In following 

 the rail-road from Coventry towards Birmingham, the underlying or deep red 

 sandstone is traversed ; and in the adjoining hill of Meriden, it is again capped 

 by the same light-coloured rock as at Coventry. The red sandstone continues 

 as far as Berkswell, where it is succeeded by the upper marls of the Knowle 

 basin, which extend to within a mile of Birmineham. At Berkswell a sin"u!ar 

 variety of this sandstone occurs, exhibiting the appearance of a pavement of 

 bricks, 2 or 3 inches square, separated by bands of a whitish cement. The 

 stone splits into thin flags, and the division in the colours extends through each 

 layer. No change of texture is visible in the white bands from the red por- 

 tions which they inclose; but along the centre of each is a fine raised line, 

 apparently due to a cast in an extremely narrow crack. The following wood- 

 cut represents a fragment of this stone. 



A similar sandstone is stated by Dr. Macculloch to occur in the coal-mea- 

 sures of Arran. Description of the Western Islands, vol. ii. p. 374.
