Dugès (1891:485) described _Eumeces altamirani_ from "las regiones cálidas del Estado de Michoacán" and subsequently (1896:480) gave Apatzingán as a locality for the species. Presumably he had only one specimen. In 1935 Hobart M. Smith collected the species at El Sabino on the lower slopes of the Cordillera Volcánica bordering the Tepalcatepec Valley. All of the known specimens are from this valley and the adjacent slopes, an area to which the species apparently is endemic. ~Eumeces colimensis~ Taylor _Eumeces colimensis_ Taylor, Publ. Field Mus. Nat. Hist., zool. ser., 20:77, May 15, 1935.--Colima, Colima, México. Coalcomán; Salitre de Estopila. The species was reported by Peters (1954:16); no additional material has been discovered. The species is known only from foothills and low mountains at elevations between 130 and 950 meters in Michoacán and Colima. ~Eumeces copei~ Taylor _Eumeces copei_ Taylor, Proc. Biol. Soc. Washington, 46:133, June 5, 1933.--10 miles southeast of Asunción, México, México. Cerro Tancítaro (3); Zacapu. This member of the _Eumeces brevirostris_-group has been found only in pine or pine-fir forests at elevations from 1800 to 2700 meters. It probably ranges throughout the high mountains of the state north of the Tepalcatepec Valley; its apparent absence in other parts of the Cordillera Volcánica, other than on Cerro Tancítaro, is surprising. The species has been taken near Asunción in the state of México and at Lagunas de Zempoala in Morelos. In this species the lateral pale yellow stripe, which is bordered below by dark brown, extends to the groin and onto the base of the tail. The dorsolateral stripe is separated from the copper-colored middorsum by a narrow brown stripe. ~Eumeces dugesi~ Thominot _Eumeces Dugesii_ Thominot, Bull. Soc. Philom. Paris, ser. 7, 7:138, 1883.--Guanajuato. Type locality restricted to Guanajuato, Guanajuato, México, by Smith and Taylor (1950b:169). Carapan (6); Cherán (5); Opopeo (2); 17 km. S of Pátzcuaro (3); San José de la Cumbre (2); Tancítaro (2); Tangancícuaro; Uruapan; Zacapu. Individuals of this species frequently have been found beneath rocks and logs in pine-oak, pine, or fir forests from elevations of 1550 to 1850 meters. To judge from specimens available, _E. dugesi_ probably is the most abundant and widespread species of skink in the state. In this species the lateral yellow stripe is indistinct and is persistent only in the axilla; the dorsolateral stripes terminate anterior to the hind limbs and are not separated from the tan dorsum. ~Eumeces indubitus~ Taylor _Eumeces indubitus_ Taylor, Univ. Kansas Sci. Bull., 21:257, November 27, 1934.--Near Cuernavaca, Morelos, México. Puerto Hondo.
