At the January meeting of this Society in 1882, I laid 

 before you the results of my investigation of some Arthropod 

 remains from the Lower Old Red Sandstone of Forfarshire, 

 which had up to that time been considered to belong to 

 Isopod Crustaceans, but which proved to be the remains of 

 Chilognathous Myriapods, belonging to two genera. One of 

 these had already been named Kccmpecccris by Page, while to 

 the other I gave the name of Archidesmus. Since then, 

 Scudder, the authority on Fossil Insects, has raised these to 

 family rank under the name of Archidesmidae, which family 

 falls into his order of Archipolypoda, comprising all the 

 Palaeozoic Myriapods, with the exception of some anomalous 

 creatures covered with bundles of peculiar spine-like hairs, 

 and a few forms from the Devonian rocks of St John, New 

 Brunswick, which are considered by Gr. F. Matthew to belong 

 to the great division of the Myriapods, the Chilopoda.^ 



At the time of the reading of my paper, these Myriapods 

 were the oldest air-breathers that had then been described. 

 Shortly afterwards, in 1884, Lindstrom announced the dis- 

 covery of a scorpion, Palceophonus nuncius, from the Upper 

 Silurian rocks of Gothland, which was afterwards described 

 by Thorell and him.- About the same time I gave a short 

 description of another specimen belonging to this species 

 {Palceophonus caledonicus) which was brought to me by the 

 late Dr Hunter-Selkirk of Carluke, and which had been 

 found in the Upper Silurian rocks of the Lesmahagow inlier 

 about a year previously.^
