Utner collections ought to be made before sufficient material will have been secured to enable the naturalist to discriminate between actual residence and some few species which may owe their presence to storms or atmospheric currents, and thus would not properly belong to this fauna. Bnt with each comparison of collections the constant recurrence of certain species will designate those which should be regarded as conterminous. It is a difficult matter to determine a vertical limit for alpine species, because a few forms occurring in the foot- hills sometimes encroach upon the ver~ e of the alpine flora. The altitude of 12,000 feet above the level of the sea, which is about 300 feet above timber- line, has been therefore selected as the elevation best calculated to yield a collection characteristically boreal; and all species below enumerated were accordingly taken at a considerable altitude above timber- line.
