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 pidchra. 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 recog- 

 nized as distinct species occupying separate areas in different 

 faunal zones. 



If then we ignore the localities of the type specimens of 

 '■'■A. texatia'" and A. nigra, as open to question until con- 

 firmed 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 Diego County. 



San Diego, Coronado, mountains near San 

 Diego.
