ly. The throat and belly are white, more or less suffused 

 with blue; the latter sometimes with large brown lateral

Dr. Stejneger has given* the following description of 

 the fresh colors of a young individual obtained near the 

 Little Colorado Kiver, Arizona: — 



"Head above pale sepia, inclining to clay color; an- 

 terior portion of upper neck in front of the first black 

 collar pale blue, with several longitudinal marks of 

 'coral red;' space between the two black collars pale 

 'oil green,' with a narrow transverse collar of coral red; 

 ground color of back dull oil green, fading posteriorly 

 on hind legs and tail to a grayish ' pea green,' the back 

 densely covered with rather large dark grayish olive 

 blotches, which only allow the ground color to show 

 through as a fine reticulation; the second black collar 

 bordered posteriorly with a wide line of ' lemon yellow,' 

 the back being crossed by five similar lines, fading pos- 

 teriorly and more or less alternating on the lateral halves 

 of the body; tail with transverse bars of dark grayish 

 brown; fore legs above 'apple green,' nearly yellow on 

 hand and faintly barred with the latter color; under 

 surface pale greenish-white, palms slightly pinkish, tail 

 nearly white. Tongue deep pink; pharynx blackish 

 carmine; palate ultramarine blue. Iris brassy greenish- 

 yellow."
