162 C. W. Hayes-Expedition through the Yukon District. seven are from Taku and four from Prince William sound. The total number of species from Taku is twelve, while eleven were obtained at Prince William sound. It is thus seen that the percentage of arctic and alpine forms from Taku is considerably the larger. Only one of the lichens is confined to the western coast. It is greatly to be regretted that all the valuable collections which Dr Hayes made in the interior had to be abandoned because of lack of means of transportation. In the determination of these plants I have been indebted for aid to Professor L. M. Underwood, who examined some of the Hepatics, and to Professor A. B. Seymour, who compared several of the lichens with the collections in the Tuckerman herbarium. WELLESLEY COLLEGE,April 21, 1892.
