“ The University of Kansas Museum of Natural History received from J. R. Alcorn and Albert A. Alcorn a sizable collection of mammals taken in the summer of 1951 in Alaska. In addition to visiting localities at which they had collected in 1947 and 1948 (see Baker, Univ. Kansas Publ., Mus. Nat. Hist., 5:87-117, 1951) the Alcorns obtained specimens from localities not previously visited in the vicinity of Anchorage and Haines and from Sullivan Island, a small, timbered island in the Lynn Canal. A part of the funds for field work was made available by the Kansas University Endowment Association. ”

“ Water Shrew.—Two males taken on August 5, at Peters Creek, elevation 300 ft., 20 miles NE of Anchorage provide a northwestern extension of the known [Pg 476] range of this species. In external and cranial characters the males resemble S. p. navigator from 9 miles W and 4 miles N of Haines, Alaska, and from Washington County, Idaho. The specimens from Peters Creek do not agree with the description of Sorex alaskanus Merriam as given by Jackson (op. cit.:189) although one, a second year animal, has the lambdoidal crests exceptionally well developed, as does S. alaskanus. ”

“ 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. ”
