has not yet been shown to be the case. Fischer, to be sure, 

 states that the type of A. nigra came from San Diego, where 

 A. pulchra is especiall}^ abundant, but it is quite possible that 

 his specimen did not really originate there. All of the dark 

 specimens I have seen, have been secured on the coast of 

 Monterey Covmty; and, aside from Fischer's, I know of no 

 records of the black Anniella from any other locality, except 

 Cope's^ reference to specimens from San Francisco. Aside 

 from the type locality, then, it would seem that the dark form 

 has a very limited range, being confined to the southern part 

 of the Pacific Fauna of the Transition Zone. 



In a large series of alcoholic specimens from the coast of 

 Monterey County, I find very few showing a style of colora- 

 tion similar to that of A. piildira. A specimen from San 

 Ardo, in the interior of this county, is typical of A. pulchra, 

 but San Ardo is in the Upper Austral Zone. Not more than 

 four or five of the fifty-four specimens from the coast zone 

 could be in the least confusing, and all of these are more 

 deeply pigmented above than is any example of A . pulchra 

 before me. Forty-eight of these specimens were sent me 

 alive, and in that condition exhibited a greater range of color- 

 ation than they show since preservation in alcohol, which 

 seems to have intensified their dark pigmentation while dis- 

 solving the beautiful yellow of their lower surfaces. When 

 the living lizards were received from Carmel and Point Pinos, 

 they were divided into ten groups according to the intensity 

 of the dorsal pigmentation, and measurements were taken of 

 each specimen in each group. These grades of pigmenta- 

 tion of the living specimens, with measurements in millimeters 

 from snout to anus and anus to tip of tail, are as follows : 



I. Entire upper surface (ten, twelve, or fourteen rows of 

 scales) and ventral surface of tip of tail very dark Indian 

 purple. Chin and throat lighter Indian purple. More or 

 less suffusion with Indian purple about anus. Rest of lower 

 surfaces and sides bright gamboge yellow with chromium 

 green staining near center of belly. Mouth flesh-color. 

 Labials and temporals minutely dotted with iridescent green-
