cki_ of Zweifel) in the Tepalcatepec Valley.

There is considerable geographic variation in the number of dorsal
granules around the midbody. Sixteen specimens from the coastal regions
of Michoacan have 129-146 (136.3) granules; nine from the Tepalcatepec
Valley have 124-137 (128.3), and 44 from Coalcoman at an elevation of
950 meters in the Sierra de Coalcoman, intermediate geographically
between the coast and the Tepalcatepec Valley, have 105-144 (119.7). The
number of granules in specimens from the coast of Michoacan compares
favorably with the range of 118-154 (137.8) for 34 specimens from
Colima, Colima (Zweifel, 1959a:107). Aside from the characters given in
Table 5, _C. communis communis_ can be distinguished from other members
of the _Cnemidophorus sexlineatus_-group (_calidipes_, _costatus_, and
_scarlaris_) by its relatively small post-antebrachial scales.
