Washington Publ. 473:107, November 20, 1936. _Type._--Male, subadult, skull and skin; no. 32019/43828, U. S. Nat. Mus., Biol. Surv. Coll.; Grants Pass, Rogue River Valley, Josephine County, Oregon; December 19, 1891; obtained by C. P. Streator; original no. 1404. The skull (plates 19-21, 30) is complete and unbroken. P3 on the left side is missing. Otherwise the teeth all are present although worn probably as a result of gnawing at the trap which captured the specimen. The skin, in brown, winter pelage, is fairly well made. Although the label on the skin and the label in the skull vial each give the sex of the specimen as female, and although Merriam (1896:25) regarded the specimen as a female, the present writer regards the specimen as a male. It is as large as other undoubted males and larger than any known female of this subspecies. The labels with the skull and skin give the locality as "Rogue River Valley, Oregon." The listing here of the more restricted locality, Grants Pass, is made on the basis of Merriam's (1896:25) original description of the subspecies.
