_Remarks._--The jumping mice listed above have been compared with specimens of _Z. h. hudsonius_ from Ontario and Michigan. The zone of contact between _Z. h. hudsonius_ and _Z. h. alascensis_ is still unknown; Alcorn obtained no specimens between Irons Creek and Whitehorse. To my knowledge there are no records from this extensive area.
Alcorn took _Zapus_ in gra.s.sy areas at the edge of water, in an old gravel pit, and at the site of an old sawmill. Animals were taken as early as June 30 and as late as September 2.
