"The eastern fence lizard (S. undulatus) and western fence lizard (S. occidentalis) are shown to be sympatric in a woodland community in the Pine Valley Mountains, Washington County, Utah. Observations on external morphology and chromosomes, involving 49 specimens from the area of sympatry, produced no evidence of interbreeding. These forms are properly regarded as different species. The 16 S. occidentalis karyotyped from the Pine Valley Mountains included a triploid female that was sterile but otherwise appeared normal. Specimens of S. occidentalis have been karyotyped from many localities throughout its range (Utah to California, Washington to Baja California Norte), and, normally, all individuals are alike in chromosome morphology. However, four specimens out of 12 from northwestern California (Del Norte, Trinity, and Shasta counties) had a heteromorphic pair of chromosomes that were not sex-correlated. Following a generally overlooked paper by Harper, the authorship of the name Stellio undulatus (= Sceloporus undulatus) should be credited to Bosc and Daudin (in Sonnini and Latreille, 1801)"--P. [1].
