Perhaps Howell later came to modify his position. Warren (1942:75) stated: "A. H. Howell . . has recently ex- amined my series of skunks, and writes me that he has come to the conclusion that there is only one species of skunk [in Colorado]." Cary (1911:178) treated striped skunks in Colorado as two species, Mephitis hudsonica and Mephitis mesomelas, the latter represent- ed by two subspecies, varians and estor. Mephitis mephitis estor Merriam Mephitis estor Merriam, N. Amer. Fauna, 3:81, 11 September 1890; type locality, Little Spring, 8200 ft., N base of San Francisco Mountain, Coconino Co., Arizona. Mephitis mephitis estor, Hall, Univ. California Publ. Zool., 37:1, 10 April 1931. Distribution in Colorado.—Southwestern part of state (Fig. 106). Comparisons.—From both M. m. hudsoni- ca and M. m. varians, the subspecies estor differs in smaller external and cranial size and in more extensive white markings. Measurements.—External measurements of a male from Coventry, Montrose County, are: 764, 312, 86. Mean (and extreme) cranial measurements of five males, followed by those of five females, all from La Plata County, are: condylobasal length, (), (); zygomatic breadth, ( ), (); postorbital constric- tion, (), (); mas- toid breadth, (), ( ); length of maxillary toothrow, (), (). Remarks.—Durrant (1952:432) tentatively referred to M. m. estor two immature indi- viduals from Uintah County, U
