eral dark markings is often lighter than elsewhere. Most of 

 the lateral scales occupied by the dark bars are tipped with 

 white. The coloration of the tail is similar to that of the back. 

 The head and limbs may be either unicolor or irregularly 

 mottled with black or brown. The lower surfaces are white, 

 yellow, green, or gray, often with dark gray or slate-colored 

 lines which, when present, appear between the longitudinal 

 series of scales. 



The young are similarly colored, but the dorsal bands 

 are always broken and the medial spots are much smaller 

 than is usual in adults. The ground color of newly-born 

 young is an irridescent bronze.

Distribution. — Burnett's Alligator Lizard occupies, so far 

 as is at present known, merely a narrow strip of country ex- 

 tending along the coast of California from Monterey to 

 Humboldt and Shasta counties. Parts at least of this area 

 it holds in common with its larger congener G. s. scincicauda, 

 for the ranges of the two species overlap at certain points. 



Specimens have been collected in Siskiyou (South Fork 

 of the Salmon River, Sisson), Shasta (Sweet Briar Camp), 

 Trinity (Coffee Creek), Humboldt (Trinidad, Areata, 

 Alton, Carlotta, Eureka, Philipsville, Cuddeback), Tehama 

 (two miles south from Yolla Bolly Mountain), Mendocino 

 (Irishes, Alder Creek, Sherwood, Willits, Lake Leonard, 

 Comptche, Mendocino City, Gualala, Lierly's Ranch four
