PEBMIAN GROUP. 87 



The name, Pennian, was suggested by Sii E. I. Mur- 

 chison, from the strata of this group covering an extensive 

 area in the government of Perm, in Russia. The fauna 

 and flora of this group are rather peculiar, presenting a 

 general analogy with those of the carboniferous system 

 upon which it reposes, and containing some species that 

 are common to both eras ; thus associating its position 

 with the Palaeozoic Series. 



LOCALITIES rOR FOSSILS, &c. 



The quarries at Hmnbleton Hfll, &c., near Sunderland, afford most of 

 the characteristic fossil shells ; Coflyhurst, near Manchester, for

 forth Quarry, near Leeds, and very perfect remains of fish are 

 obtained from Ferry Hill, Durham. 



Saurians occur at Durdham Down, near BristoL
