Bronzed drab-gray above; pale wax-yellow below; chin light Indian purple. 92 41 Two lateral lines Very distinct dorsal line These notes show clearly that the intensity of pigmentation increases quite gradually and fairly regularly with the size of the individual, and that while young specimens may be nearly as pale as some dark individuals of _A. pulchra_, all of the large specimens are of the dark type. It is also true in a general way that the smaller the specimen the more distinctly the lines are shown. In the light of our present knowledge, therefore, it seems necessary to regard _Anniella nigra_ as a local and probably recently differentiated race rather than as a melanistic phase of _Anniella pulchra_. While the difference is purely one of color, no intergradation has yet been shown to occur in adult specimens, and the two forms must therefore be recognized as distinct species occupying separate areas in different faunal zones. If then we ignore the localities of the type specimens of "_A. texana_" and _A. nigra_, as open to question until confirmed by the finding of additional specimens, the known distribution of the species of the genus _Anniella_ is as follows: =Anniella pulchra.= UPPER AUSTRAL ZONE. _San Diegan Fauna._ San Diego County. San Diego, Coronado, mountains near San Diego. Riverside County. San Jacinto. San Bernardino County. San Bernardino. _Californian Fauna._ Kern County. Oil City to Poso Creek. Tulare County. Sequoia National Park. Fresno County. Fresno. Monterey County (interior). San Ardo. San Benito County. Bear Valley. Contra Costa County.
