The upper part of the permian beds named in the above 

 section, consisting of red marls and limestones, contains the 

 usual permian fossils, consisting of shells of the genera Schi- 

 zodus, Bakevellia y Turbo, and Rissoa, and a sponge of the 

 genus Tragos. 



The number of beds of limestone is only 26, whereas in 

 the bore at Messrs. Kenworthy's 54 were noticed. In the 

 latter case, most of the hard beds were put down as limestone, 

 whilst in the former, only those which appeared to the work- 

 man to be limestone were noticed as such ; and sometimes two 

 or three beds were classed as one. In the former also several 

 beds were enumerated containing limestone ball-, whu 



latter were put down as separate beds. These circum- 

 stances may, in some measure, account for the great difference 

 in the number of beds. 



In my former paper, at page 238, I alluded to the occur- 

 rence of red and variegated sandstones containing impressions 

 of Catamites and SigUlaria y and pieces of fossil wood, which 

 had been found in sinking the pit at the Bedford Colliery some 

 years since ; but whether these fossils belonged to the carbo- 

 rmian strata — as both were lying on the pit bank
