Second contribution to the studies on the Cambrian faunas of North America
Herewith I have the honor to transmit the Second of my preliminary studies on the Cambrian Faunas of North America. The larger portion of the report was ready for publication July 7, 1885, but, having visited a number of localities in Utah and Nevada during the season of 1885, numerous additions have been made to both the text and the plates.Very respectfully,CHARLES D. WALCOTT.
