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).

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.
