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).
