Sceloporus horridus albiventris Smith
Sceloporus horridus albiventris Smith, Field Mus. Nat. Hist, Zool. ser.,
26:108, July 27, 1939 {type locality, Tepic, Nayarit).
Remarks.—Eight specimens of Sceloporus horridus albiventris
have the following measurements: total femoral pores, 4-6 (5.8);
dorsal scales, 30-35 (32.5); snout-vent length 64-91 (77.8). The
venter is white in four and exhibits a pale blue tint laterally in four.
The chin is white in five, has a pale blue tint in two, and is barred
laterally with gray in one. These characters are in agreement with
those presented by Smith (1939c:108). Specimens from near Culiacan
represent the northernmost locality for the species in Sinaloa.
The lizard is to be expected in the foothills to the northeast of
Culiacan as suggested by its occurrence in Chiahuahua (Tanner
and Robison, 1959:79). Individuals were collected from fence
posts, logs, and on rock piles. This species apparently is more terrestrial
than Sceloporus clarkii boulengeri.
Distribution in Sinaloa.—In the foothills and on the coastal plain
of Sinaloa south of Culiacan. See Fig. 49.

with the descriptions given by Smith (1938:624-28, 1939c:226-27).
