Fig. 1. — Section throu{>h Old Cambus Quarry to the 

 Siccar Point. 



The members of the Club, after leaving the Annelid quarry, 

 gradually wended their way through one of these denes, and 

 then turned in the direction of the coast line, and climbed 

 the bank which forms the cliff at the Siccar Point — "The 

 Mecca of Geologists" as it has been termed. Before making 

 the descent from the top of the cliff, a brief outline was 

 given of the geological features to be seen on the south side 

 of the Swallow Cave. On the left, looking seaward, was 

 the Upper Old Red Sandstone lying upon the Silurian Rocks ; 

 next to this is a small fault which has a down-throw to the 

 south, so that the Old Red Sandstone is let down, and thence 

 occupies the shore southward for some distance. The writer 

 of this note has found scales of Holoptychius nohilissimaSy 

 one of the preeminently characteristic fossil fishes of the 

 Upper Old Red Sandstone, in the red sandstones on the foreshore 

 here. They have been found, of course, by other geologists 

 on various occasions, at and near the same spot. The remains 

 of another characteristic fossil fish — peculiar to this district, 

 so far as is yet known — may be looked for here with a reason- 

 able prospect of finding them, seeing that they occur at 

 several other localities in the Merse. This is Bothriolepis 

 obesa, a strange extinct form of fish allied to Fterichthys. 



Reaching the top of the cliffs, above the chief object of 

 the day's excursion, the party slowly and cautiously made 

 their way by a zig-zag path to the foot of the cliff, where 

 the leader called attention to the outstanding features, and 

 afterwards gave a more detailed account of the matters of 

 interest, of which the following may be taken as a report.
