152 BULLETIN 17 5, UNITED STATES NATIONAL MUSEUM 



red is present, and on the tail where a normal specimen is black, only pale bluish 

 or uncolored areas are to be seen. The iris and tongue which are normally dark 

 shared in the loss and were of a light pinkish cast. Evidently the factor controlling 

 the formation and deposition of black pigment failed of operation throughout the 

 entire body. 



Accompanying this abnormality in coloration there were irregularities in scale 

 pattern, especially on the head, which suggests that whatever cause operated to 

 prevent the formation of black pigment also may have some effect on scale 

 formation. Several of the head scales are of quite different shape than those 

 found on a normal specimen, and some show suggestions of divisions which were 

 not completed. 



Range. — This form ranges from San Diego County, Calif., to Wash- 

 ington, and one specimen has been taken in Vernon, British Colmnbia. 

 It occurs also on Santa Cruz Island, off the coast of California. It is 

 found as far east in California as Kernville, Kern County; in the 

 southern part of the range as Eldorado and Placer Counties farther 

 north; and as the Warner Mountains in the northeasternmost part of 

 Modoc County. In Oregon it is found as far east as Summer Lake, 

 Lake County, in the southern part, and as Heppner, Morrow County, 

 in the northern part. In Washington it is found west and north of 

 the Columbia River. In the eastern parts of Oregon and Washington 

 it is replaced by deserticola.
