the lowlands of
Colima and the Balsas-Tepalcatepec Basin inland to northern Guerrero and
Morelos; a southern population inhabits the Plains of Tehuantepec in
Oaxaca.

A juvenile from Apatzingan (USNM 47739) has a snout-vent length of 40.0
mm. and a tail length of 19.5 mm.

This small terrestrial species inhabits the pine and fir forests of the
Cordillera Volcanica between elevations of 1850 and 3100 meters;
apparently it is absent from the Sierra de Coalcoman. It seems to prefer
rather open coniferous forests in which there is a more or less
continuous cover of grasses on the ground. On warm sunny days the
lizards can be observed scurrying about in the grass; in the early hours
of the day, or on cold days, they are found beneath stones, logs, or
dead clumps of bunch grass.

~Sceloporus asper~ Boulenger

_Sceloporus asper_ Boulenger, Proc. Zool. Soc. London,
1897:497, October, 1897.--La Cumbre de los Arrastrados,
Jalisco, Mexico.

Apatzingan (3); 10 km. E of Dos Aguas; Uruapan (41).

This strictly arboreal lizard is abundant in the mixed broad-leafed
forest near Uruapan. The lizards are exceedingly wary and can be
approached only with difficulty. In life males have pale blue bellies;
the throat is pale pink. The pale gray dorsum marked with irregular
darker gray blotches blends well with the color of the tree trunks on
which the lizard lives. The one specimen from Dos Aguas was found on a
pine tree; it provides the only record for the species from the Sierra
de Coalcoman.
