18. Peromysous oanadeniis (Miller). Canadian Deer Mouse.
Four typical specimens of this distinct species were taken in the primeval forest about two miles from Eaglesraere. They were not found in a similar forest in Clinton County, leiicopus only being taken there. It is likely that typical canadensis is not found in Pennsylvania except along its northern border, in the roost boreal environments of the mountain tops in isolated localities. Along the culminating ridge, southward, it intergrades
...into the following sub- species, inhabiting the loftier summits of the southern Alleghenies.' 19. Peromyioai oanadexuis nnbiterrsB (Rhoads).^ Cloudland Deer Mou^e.
Of great interest, as showing the true relationships of the long- tailed, dusky deer mouse of the balsam forests of Tennessee and North Carolina, is a series of 29 Peromyscus taken in Cambria and Somerset Counties, Pennsylvania, by Mr. Ingersoll. Nine of these were trapped at Kring's Station, the remainder at Summit Mills. In size and proportions these are conclusively connectant between the large form found in Canada and New England and the diminutive cloud-dweller of the Great Smoky Mountains.
