I have personally collected blakei in^ a scrubby fir forest at 3800 feet on the sum- mit of Big Equinox Mountain, Bennington Co., Vermont, where it was abundant under the bark of both standing and fallen dead trees. The distribution of ]}Ia]<ei follows exposures of limestone and marble up to the Adirondack's, where it is also found on other substrates. This distributional pat- tern seems to clearly indicate that ])kikei followed the boreal forests north with the retreat of the Wisconsin ice at the end of the Pleistocene, leaving behind relict popu- lations in suitable habitats, such as lime- stone caves. The cave populations described bv Loomis (1939) as voga differ hardly at all from the typical form of blokei, except that the pigmentation is much weaker in some specimens and the arrangement and size of the ocelli is somewhat irregular.
