define accurately the
subspecies and their ranges. Peters (1954:29) assigned the specimens
from Coalcoman to _R. h. hesperioides_.

In life the specimens from Arteaga had bright cream-colored temporal
stripes and dorsolateral stripes on the anterior part of the body. The
chin and anterior one-sixth of the belly was white; posteriorly the
venter was bright orange-red.

In Michoacan this snake has been found in tropical semi-deciduous
forest, arid scrub forest, and pine-oak forest at elevations from 850 to
1500 meters.

This snake is abundant in the Cordillera Volcanica, but it is unknown in
the mountains to the northeast of Morelia or in the Sierra de Coalcoman.
Most specimens were found beneath volcanic rocks imbedded in the ashy
soil in pine forest between 1800 and 2300 meters.

Tancitaro (2).

This species, which is known only from a small region in the mountains
of Jalisco and central Michoacan, is represented by two specimens (CNHM

This species is abundant on the Mexican plateau, where it inhabits the
more grassy areas in the mesquite grassland and cutover land in the pine
forests from 1550 to 2500 meters. Davis and Dixon (1957:21) described a
specimen from Zacapu as having two dark paravertebral stripes diverging
on the temporals and extending through the eye onto the loreal, a
characteristic of _Salvadora lineata_. On the ba
