 1848 Middle Marine Series with Permo-Carboniferous 

 fauna. Details. — Black shales impregnated 

 with alum. Sandstone 100 feet thick packed 

 full of Productus ClarJcei (P. brachythcerus (?)) . 

 Grey and yellow sandstones, blue and grey 

 shales with here and there bands of reddish 

 ferruginous, probably once calcareous sand- 

 stones, sometimes varying to sandy impure 

 ironstones very full of fossils as casts : while 

 in the grey sandstone the substance of the 

 shell is preserved. Upright rootlets occur in 

 the sandstones and shales, and coniferous 

 trunks in the sandstones. Conglomerate 

 bands, the fragments composed of granite, 

 schist, slate, quartzite and porphyrite, some 

 of the granite blocks measuring four cubic feet. 

 These erratics occur in groups. Corals.

 tain Glossopteris, are apparently overlaid by 

 beds containing Streptorhyncus crenistria.
