Appendix I. 



Old Cambus, The Siccar Point, and Cove. By J. G. Goodchild, 

 of the Geological Survey, F.G.S., F.Z.S., Ctistodian of the 

 Collection of Scottish Mineralogy in the Edinburgh Museum 

 of Science and Art. 



(I.) The Quarries of Old Cambus. 



These quarries are excavated in highly inclined, and, 

 perhaps, even inverted, beds of greywacke and argillite of 

 Silurian age, and belong to that lower part of the Silurian 

 Rocks which are the equivalents of the Tarannon Eocks of 

 Wales, and the Pale Slates of the English Lake District. 

 The Scottish type of development of these rocks is now 

 usually referred to by Professor Lap worth's name of the Gala 

 Group. They contain many traces of animal life, chiefly in 

 the form of the so-called "annelids," whence the name of 

 " Annelid Quarry," often given to the place in question. 

 With these problematical fossils there occur several species 

 of the curious old-world organisms known by the name of 

 graptolites. Of these the following species have been obtained 

 from Old Cambus quarry by either the writer of this note, 

 or by other persons, in his presence: — 



Monograptus crispus. 

 exiguus. 

 turriculatus. 

 attenuatus. 

 vomerinus.
