Coalcoman (3); El Sabino (3); Uruapan (5).

The range of _Leptodeira splendida bressoni_ apparently does not overlap
that of _Leptodeira maculata_; the latter is restricted to the lower
reaches of the arid scrub forest, whereas _L. s. bressoni_ inhabits the
upper limits of the arid scrub forest and the lower part of the pine-oak
forest. Specimens have been collected between 950 and 1630 meters on the
slopes of the Cordillera Volcanica and at 950 meters in the Sierra de
Coalcoman. At Uruapan individuals were found beneath rocks along a
stream and in a stone fence. _Leptodeira duellmani_, which was described
from Coalcoman by Peters (1954:25), is an aberrant individual of _L. s.
bressoni_ (Duellman, 1958a:56).

Most specimens of this species have been collected in tropical
semi-deciduous forest at elevations of less than 1000 meters. In the
Sierra de Coalcoman one was taken in pine-oak forest at an elevation of
1700 meters near Ocorla; another was found in broad-leafed forest
between Aguililla and Dos Aguas at an elevation of 1600 meters. Most
individuals have been seen in trees or bushes. The absence of
broad-leafed forest in the Tepalcatepec Valley probably accounts for the
absence of this snake in that area.

In Michoacan the species has been found only in tropical semi-deciduous
forest on the lower slopes of the Sierra de Coalcoman. From the
observations made by Peters (1954:28), this snake is diurnal and feeds
on teiid lizards.
