Excerpt from Bulletin From the Laboratories of Natural History of the State University of Iowa, Vol. 6: May 13, 1911 When I came to the University of Iowa last September, Prof. C. C. Nutting placed at my disposal two collections from San Juan Archipelago, not previously examined, the one made by Mr. H. Moon, a graduate of the University of Iowa, and the other by Prof. T. Kincaid of the University of Washington, Seattle. The collection belonging to the University and Prof. Nutting's own collection, both extensive, have been available for reference and comparison. A collection made at Canso, Nova Scotia, under the supervision of Prof. R. Ramsay Wright, while connected with the University of Toronto, was also of value in comparing the West Coast forms with those on the Atlantic Coast. These col lections, then, form the basis for the work set forth in this paper. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
