form, Page's name of Kampecaris forfarensis was retained, 

 but a new genus, Archidesmus, had to be erected to hold 

 another species, which was called A. Macnicoli after the 

 finder, Mr Walter Macnicol, of Tealing. Scudder afterwards 

 made these forms the type of a family, the Archidesmidse, 

 which fell under his order of Archipolypodidse. 



In 1898 I made a further communication to our Society, 

 describing a species of Archidesmus, A. Loganensis, from the 

 collection of the Geological Survey, which was found by 

 Messrs Macconochie and Tait in the Upper Silurian (Lud- 

 low) rock of Logan Water, near Lesmahagow,i thus carrying 

 back the history of these old air-breathers a stage farther. 

 In the same paper I described a new genus of lulus-like 

 form, which I named after the late Mr Paton, who obtained 

 it from the Carboniferous limestone of East Kilbride, and 

 which was acquired by the Museum of Science and Art from 

 the late Mr Coutts of Glasgow, after whom it is specifically 

 named. In the same paper it was found necessary to erect 

 a new genus, Anthracodesmus, to contain a form strongly 

 resembling the recent Polydesmus, both in outward form and 

 in the pattern of the sculpturing, which was specifically 

 named after A. Macconochie, who collected it from the 

 Calciferous sandstones of Lennel Braes, near Coldstream. 

 A species of Kampecaris, K. obanensis, was also described 

 from the Lower Old Eed Sandstone rocks of Kerrera, 

 near Oban, collected for the Geological Survey by A. 

 Macconochie. 



INSECTA. 



Although the Scottish Carboniferous rocks have produced 

 Scorpions and Myriapods in considerable abundance, Insect 

 remains are of rare occurrence. In 1887, however, Dr H. 

 Woodward described, under the name of EtoUdttina Peachii, 

 the remains of an interesting Cockroach, showing characters 

 that are found in the larval stages of its recent congeners. 

 The specimen was found by Mr Sinclair in a nodule in the 

 Coal- Measures, at Kilmaurs, in Ayrshire.^
