THE CAKBONIFBfiOUS DI8TBI0T OF COLCHE8TEH AND HANTS. 'J -Si 



of Colchester ami Hants at least, a mure minute general subdivision. 

 1 would still, however, group sections (a), (b), and (c), as the Lower 

 es, which 1 believe can be traced throughout Nova Scotia, and 

 lions (d) and (<•) as the Upper series, which is also very generally 

 distributed. To these I would add a third group (/), including the 

 Upper Carboniferous marine limestone of Wallace, with I'roductus 

 nmireticulatus (?), a small and depauperated form, Avundopeeten sim- 

 plex, Terebratula sacculus, and Cardiomorpha, sp. Taking this view, 

 the following table will give the distribution of these sub-formations 

 M far as known to me : —

 Nora Scotia {in descending order).
