=_Microtus oeconomus macfarlani_= Merriam. Tundra Vole.--Five specimens from 5 miles NNE of Gulkana, Alaska, 1700 ft., and four from Peters Creek, elevation 300 ft., 20 miles NE of Anchorage, Alaska, are assigned to this subspecies. In color they resemble _macfarlani_ from eastern Alaska (14 miles E and 25 miles N of Fairbanks) and are darker than _M. o. operarius_ (Nelson) from Tyonek, but judging from the description by Bailey (N. Amer. Fauna, 17:41, 1900), are not so dark as _M. o. yakutatensis_ Merriam. These mice were taken inland from the coast. It is likely that the coastal population more nearly resembles either _operarius_ or _yakutatensis_. =_Erethizon dorsatum myops_= Merriam. Porcupine.--Skulls of two females obtained from the Chilkat Peninsula, elevation 10 ft., 7 miles SSE of Haines, Alaska, agree with those of the same sex of _myops_ from Yerrick Creek, Alaska, and from 2 miles W of the Teslin River, Yukon Territory. The skull of the older animal has the longer nasals and more pronounced cranial ridges, which perhaps indicate a tendency toward _E. d. nigrescens_ Allen, which occurs to the southward (see Anderson, Canadian Jour. Res., 21:304, 1943). _Transmitted October 8, 1953._
