with grey, red, and brown sandstones, the red beds becoming more 

 prevalent in the upper part of the section. In Prince-Edward 

 Island beds apparently corresponding to these are found, and also 

 gradually become more red in ascending. These are overlain, ap- 

 parently conformably, by the Trias. 



The author gave a tabular list of 47 species of plants found in the 

 Upper Coal-formation of Nova Scotia and Prince-Edward Island, 

 and stated that all but about ten of these occur also in the Middle 

 Coal-formation. The number of species decreases rapidly towards 

 the upper part of the formation ; and this is especially the case in 

 Prince-Edward Island, some of the beds in which are considered by 

 the author to be newer than any of those in Nova Scotia. The 

 plants contained in the upper deposits were compared with those of 

 the European Permian, and a correlation was shown to exist be- 

 tween them ; so that it becomes a question whether this series was 

 not synchronous with the lower part of the Permian of Europe, 

 although in this district there is no stratigraphical break to esta- 

 blish a boundary between Carboniferous and Permian. The author 

 therefore proposes to name these beds Permo- Carboniferous, and 

 regards them as to some extent bridging over the gap which in 

 Eastern America separates the Carboniferous from the Trias.

The author commenced by describing in detail the series of beds 

 between the true Basement series of the Carboniferous and the 

 Mountain Limestone as shown in sections at Ash Pell. The general 

 sequence in descending order is as follows : — 



a. Carboniferous Limestone, with a few thin beds of stained sand- 

 stone and shale ; thickness not less than 1000 feet ; 



b. Obliquely laminated soft red sandstones, with coal-measure 

 plants, frequently conglomeratic, alternating with fossiliferous 

 shales and beds of limestone ; thickness about 500 feet ; 



c. Limestone, 500 or 600 feet thick, passing down into 



d. Shales with thin impure limestones, passing down through 

 calcareous conglomeratic beds into a series of apple-geeen 

 quartz conglomerates and chocolate and grey shales, succeeded 

 without any clear line of separation by the drift-like red con- 

 glomerates, sandstones, and shales forming the lower part of the 

 Carboniferous Basement beds, which has been regarded as the 

 equivalent of the Upper Old Bed elsewhere. 



The author described the mode of occurrence of these deposits in 

 various parts of the district under consideration, and the disturb- 

 ances which have affected their surface distribution. Along the 

 Cross-Fell escarpment a group of sandstones and conglomerates 

 occupies an exceedingly prominent position, especially at and near
