On some remarkable annelid remains from Arthur River, N.W. Tasmania

Some little while ago the Government Geologist of Tasmania, Mr. P. B. Nye, M.Sc., B.M.E., forwarded to me at the National Museum, Melbourne, for determination, a specimen of slaty shale with fossil impressions. The rock must have originally been of the nature of a fine, slimy, or plastic mud, for the impressions are very well preserved.
