_Lacerta obricularis_ Linnaeus, Systema naturae, ed. 12, 1:1062, 1789.--México (by inference). Type locality restricted to México, Districto Federal, by Smith and Taylor (1950b:97). _Phrynosoma orbiculare orbiculare_, Smith, Trans. Kansas Acad. Sci., 37:290, 1934. Gadow (1905:213) inferred that _Phrynosoma orbiculare_ occurred at elevations of more than 3000 feet in Michoacán. There are no specimens of this species known from Gadow's collections made in Michoacán. Smith and Taylor (1950b:98) apparently accepted Gadow's statement and recorded the species from Michoacán: "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 Michoacán. In the most recent review of the species (Horowitz, 1955), no localities are given in Michoacán. Since _Phrynosoma orbiculare_ is known from central Jalisco, Guanajuato, Queretaro, and México, its presence at least in northeastern Michoacán is to be expected, although at the present time there are no specimens known from the state. ~Eumeces brevirostris~ (Günther) _Mabouia brevirostris_ Günther, Proc. Zool. Soc. London, p. 316, August, 1860.--Oaxaca. Type locality restricted to Oaxaca, Oaxaca, México, by Smith and Taylor (1950b:168). _Eumeces brevirostris_, Bocourt, Mission scientifique au Mexique et dans l'Amerique Céntrale. Reptiles, livr. 6, p. 439, 1879. Smith and Taylor (1950b:168) Listed this species: "_Michoacán_: 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 Michoacán. ~Eumeces callicephalus~ Bocourt _Eumeces callacephalus_ Bocourt, Mission scientifique au Mexique et dans l'Amerique Céntrale. Reptiles, livr. 6, p. 431, 1879.--Guanajuato, Guanajuato, México. Dugés (1896) in a paper in which he listed several species of _Eumeces_ in México, reported _Eumeces callicephalus_ from Michoacán, but he gave no specific locality within the state. Michoacán 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 Michoacán, 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 Michoacán, interspecific competition might be a reason for the absence of _Eumeces callicephalus_ there. ~Leptodeira septentrionalis polysticta~ Günther
