 PAET II. 



(Read 20th April 1898.) 



In the first part of this paper, a brief sketch of the 

 discovery of the remains of the oldest known air-breathing 

 Arthropods was given. Before proceeding to describe some 

 new forms of Millepedes from the Silurian, Old Red Sand- 

 stone, and Carboniferous rocks of Scotland, which is the 

 main object of this paper, I purpose to give a very short 

 account of the history of the discovery of remains of 

 Palseozoic Myriapods. 



As early as the year 1845, the late Rev. P. B. Brodie, in 

 his "History of Fossil Insects," figured the remains of a 

 terrestrial Arthropod from the Coal-Measures of Colebrook- 

 dale, which Professor J. 0. Westwood, at that time, erron- 

 eously, as will be shown in the sequel, considered to be those 

 " of some large caterpillar, furnished with rows of tubercles/' 



The late Sir J. W. Dawson was the first clearly to 

 announce, in the year 1859, the discovery of remains of 

 undoubted Myriapods from Palaeozoic rocks. These were 

 brought to light by him out of the famous upright hollow 

 Sigillarian stems, exposed in the sea cliffs of Carboniferous 

 rocks at South Joggings, in Nova Scotia.^ 



In 1868 A. Dohrn described the remains of a Millepede 

 from the Permian rocks of the Saarbriick ^ coal-field. In the 

 same year, Messrs Meek and Worthen began to describe the 

 Spined Myriapods, Buphoberia, etc., preserved in nodules in 

 the Carboniferous rocks of Mazon Creek, Illinois, a locality 

 made famous by the rich treasure of Arthropod and other 

 remains which it has yielded to investigators.^ These, and 

 the other American Myriapods from Joggings, were subse- 

 quently studied and classified by Dr S. H. Scudder, by whom
