=_Tamiasciurus hudsonicus kenaiensis_= Howell. Red Squirrel.--A female taken at Peters Creek, elevation 300 ft., 20 miles NE of Anchorage, is referred to this subspecies after comparison with the published description of _T. h. kenaiensis_ Howell (Proc. Biol. Soc. Washington, 49:136, 1936), with specimens of _T. h. preblei_ Howell from Yerrick Creek, Alaska, and with _T. h. petulans_ (Osgood) from 1 mile S of Haines. =_Tamiasciurus hudsonicus petulans_= (Osgood). Red Squirrel.--Three specimens were taken on Chilkat Peninsula, elevation 10 ft., 7 miles SSE of Haines, Alaska, and one at the southeast end of Sullivan Island. These squirrels, taken in June and July, are molting on the sides, back and rump. Compared with the specimens from the mainland the male from Sullivan Island is paler on the back--near (_h_) Ochraceous-Tawny instead of near (14_j_) Sudan Brown (capitalized color terms from Ridgway, Color Standards and Color Nomenclature, Washington, D. C., 1912)--and paler on the tail; otherwise this specimen resembles those from the mainland. =_Peromyscus maniculatus algidus_= Osgood. Deer Mouse.--Osgood (N. Amer. Fauna, 28:54, 1909) reported intergradation between _P. m. algidus_ and _P. m. hylaeus_ Osgood in the "region of Lynn Canal." One female from the mouth of the Endicott River, elevation 10 ft., seems referable to _algidus_. In comparison with two topotypes of _hylaeus_ this specimen is not so dark and more nearly agrees with _algidus_ from the Chilkat River, from 1 mile W of Haines and from Dezadeash Lake, Yukon Territory. =_Phenacomys intermedius mackenzii_= Preble. Mountain Phenacomys.--An adult female was taken on 28 July at the southwestern end of Dezadeash Lake, elevation 2400 ft., in Yukon Territory (approximately 60 miles from the Alaskan boundary north of the Lynn Canal), the same place where a specimen was obtained in 1948 (see Baker, _op. cit._:104). =_Microtus longicaudus littoralis_= Swarth. Long-tailed Vole.--Six of these voles were taken on Sullivan Island (two at the northeast end and four at the southeast end) and another was trapped on the mainland at the mouth of the Endicott River. All seven resemble _M. l. littoralis_ from the vicinity of Haines. One large adult male from the island has the following measurements: Total length, 202; length of tail, 71; length of hind foot, 21; height of ear from notch, 13.
