﻿45 2 4. ANGUID& 



about size of dorsals, smooth, imbricate, and arranged in 1 2 

 longitudinal series. Number of scales between symphy- 

 seal plate and anus varying from 62 to 68. 



The ground color above, in adults, is olive, brown, yel- 

 low, red, or gray, usually paler on the sides, and crossed, on 

 the neck and body, by from nine to 1 6 continuous irregular 

 black or dark brown bands. These bands are usually of 

 about the width of one row of scales, but are undulate and 

 sometimes more or less diffused on the back. The lateral 

 scales which these bands occupy are tipped with white. 

 Sometimes the tail is marked like the back, but often it bears 

 merely a central row of small brown blotches. The head 

 and limbs may be either unicolor or irregularly mottled with 

 brown. The lower surfaces are white or yellowish, some- 

 times suffused with pale brown or gray. The abdominal 

 and thoracic regions are rarely without gray or slate colored 

 lines along the middle of each longitudinal series of scales. 



The young are at first indistinguishable in color from G. 

 cceruleus of a similar age, but the complete dorsal cross- 

 bands very soon appear.

Distribution. — The Western Alligator Lizard is known 

 to occur in Washington, Oregon and northern California. 



It originally was described from a specimen caught at 

 The Dalles of the Columbia. I have examined specimens 

 recently collected in this locality, in Wasco County, Oregon,
