an annelid, the first discovered in the Carboniferous rocks of 
this country, though Dr Hiypz has recorded two from the 
“Lower Limestone” Shale of Scotland. 
After briefly referring to the Mountain Limestone, and to 
the Shales which mark the close of that formation, the author 
passed on to consider the “Millstone Grit.” At the part where 
the section was made the dip was at an angle of 45 degrees, 
and the lower beds appeared to differ very considerably from 
the upper. The former were more sandy, and there were 
flagstones, which the author had not observed in the upper 
beds. The remains of land plants were numerous, and several 
casts of shells were obtained; but these, as well as the plant 
remains, were limited to the first 100 feet of these strata. 
The author next considered the pebble-bed, to which especial 
reference had been made in his previous Paper on the Morse 
section. The opinion there expressed. was that it did not 
belong to the “Millstone Grit,’ an opinion which had since 
been strengthened by the discovery of similar pebbles at other 
places, namely, at Plump and at Bailey Hill, where these 
pebbles cover a considerable area. The author concluded his 
very interesting and instructive Paper by correlating the beds 
which constitute the Drybrook section with the Calciferous 
Sandstones of the Scotch Carboniferous system. These are 
represented by Sandstones and Shales, which undergo litho- 
logical change in the various localities where they occur. 
Looking at the “Transition” beds of Messrs Lucy and Jonzs, 
the author gave it as his opinion that they correspond in time 
with the Calciferous Sandstones and Shales of Scotland, and 
considers that they should be grouped with the ‘“‘ Lower 
Limestone Shales.” In further support of this view it was 
stated that the Polyzoa mentioned as occurring in the lower 
Limestone Shales at Drybrook, occur also in the Red Limestone 
of Arran, which the Geological Surveyors place in the “ Cal- 
ciferous”’ series. 
In the discussion which followed, Mr Lucy spoke in 
confirmation of the views held by Mr Weruerrep, Dr Wricut
