1916-17.] The Hurlet Sequence and the Abden Fauna. 
lie on the position of the Calderwood Cement Series of the West of 
Scotland. 
On the top of the last-mentioned group come a bed of fireclay full of 
rootlets, and a thin seam of coal covered by more fireclay, and a bed of 
sandstone with worm burrows. In its upper part it becomes calcareous, and 
is crowded with fragmentary crinoid stems and Spirophyton cauda-galli. 
This limestone marks the beginning of the conditions that we have shown 
to be characteristic of the Top Marine Band in the West of Scotland, and 
at once reminds us of the exactly similar beds found at Corrieburn, 
Carriden, and Charlestown on this horizon. 
We now come to the most north-easterly of the Fife sections in the 
Lower Carboniferous Limestone Series, namely, that exposed along the 
shore between St Monans and Pittenweem. This section was first 
examined in detail by Mr Kirkby, and his table has been published on 
pp. 149-150 of the Geological Survey Memoir on Eastern Fife. The 
section is altogether about 365 feet in thickness, and we believe that its 
various members can be correlated not only with the preceding Kinghorn- 
Kirkcaldy Section, but also with all the others that have been described. 
Especially striking is the similarity between it and the Corrieburn section. 
The following table is abridged from that by Mr Kirkby : —
