ed the species from Michoacan: "above 3000 feet (Jorullo?)." Reeve (1952:940) somehow misconstrued this statement to read "Jorullo, above Zumpango (Smith and Taylor, 1950b)." Reeve did not indicate on his map (1952:939) that the species occurred in Michoacan. In the most recent review of the species (Horowitz, 1955), no localities are given in Michoacan. Since _Phrynosoma orbiculare_ is known from central Jalisco, Guanajuato, Queretaro, and Mexico, its presence at least in northeastern Michoacan is to be expected, although at the present time there are no specimens known from the state. ~Eumeces brevirostris~ (Guenther) _Mabouia brevirostris_ Guenther, Proc. Zool. Soc. London, p. 316, August, 1860.--Oaxaca. Type locality restricted to Oaxaca, Oaxaca, Mexico, by Smith and Taylor (1950b:168). _Eumeces brevirostris_, Bocourt, Mission scientifique au Mexique et dans l'Amerique Centrale. Reptiles, livr. 6, p. 439, 1879. Smith and Taylor (1950b:168) Listed this species: "_Michoacan_: No specific record." I am unaware of any specimen of this skink from the state. As presently recognized, this species contains two subspecies. One of these occurs in the mountains of Oaxaca northward into central Veracruz; the other, _Eumeces brevirostris bilineatus_, occurs in Durango southward to Jalisco, where it inhabits the Sierra Madre Occidental. Possibly the species occurs in the Sierra de los Tarascos in Michoacan. ~Eumeces callicephalus~ Bocourt _Eumeces callacephalus_ Bocourt, Mission scientifique au Mexique et dans l'Amerique Centrale. Reptiles, livr. 6, p. 431, 1879.--Guanajuato, Guanajuato, Mexico. Duges (1896) in a paper in which he listed several species of _Eumeces_ in Mexico, reported _Eumeces callicephalus_ from Michoacan, but he gave no specific locality within the state. Michoacan was included in the range of the species by Taylor (1936:298) and by Smith and Taylor (1950b:164). The species definitely is known from southeastern Arizona southward to Guanajuato. It may occur in Michoacan, but, since there are three rather widespread species of _Eumeces_ inhabiting the Mexican Plateau and associated mountain ranges in the northern and northeastern part of Michoacan, interspecific competition might be a reason for the absence of _Eumeces callicephalus_ there. ~Leptodeira septentrionalis polysticta~ Guenther _Leptodeira polysticta_ Guenther, Biologia
