A representative collection of fossils from the Middle Cambrian beds of Mount Stephen, Field, British Columbia, has recently been brought back by Mr. S. H. Reynolds, M.A., F.G.S., and presented to the Woodwardian Museum. The fauna has been described by Rominger and Walcott; and the latter has compared it to that from the Highland range, near Pioche, Nevada, and from near Antelope Spring, Western Utah. The section at Field has been described by Mr. E. G. McConnell.
