LXIII. Notes on Some Fossil Crustacea and a Chilognathous Myriapod, from the Coal Measures of the West of Scotland

I regret exceedingly that so long a time has elapsed since my attention was first drawn to these specimens by Mr. Farie, before communicating my remarks upon them to the Geological Society of Glasgow. But the delay has enabled me to obtain from Edward Binney, Esq., F.R.S. (President of the Manchester Geological Society), the loan of the original specimens of Pygocephalus Cooperi, described by Professor Huxley, and also those of the coal Limuli, from Joseph Prestwich, Esq., F.R.S., for comparison with the specimens from Glasgow. I have minutely examined the supposed Annelide, but there seems to be no reason to doubt that it is the remains of a Chilognathous Myriapod, allied to Julus, and preserved in a similar manner to the specimens discovered by Principal Dawson, F.R.S., of Montreal, in the South Joggins Coal Formation, Nova Scotia. A carefully prepared drawing of another, and much larger specimen, has been obligingly sent me by Mr. J. Young, of the Hunterian Museum, Glasgow, but I should be unwilling to determine its exact character until I had examined the original specimen. From Mr. Young’s drawing, there is reason to believe it may possibly prove distinct from the specimen now under consideration. In January, 1853, Sir Charles Lyell and Dr. Dawson read, before the Geological Society of London,* an account of their examination of the stump of an erect fossil tree in the Coal-measures of Nova Scotia, containing the remains of a reptile (the Dendrerpeton Acadianum, Wyman and Owen), and of a land snail, This 250-word extract was created in the absence of an abstract
