coral red in scapular region; first pair of scapular bands of 
black separated above by a V-shaped band of sepia; back sepia 
gray with small yellowish white spots; upper aspects of legs 
greenish; upper surfaces of hand and fingers yellow three or 
four spots of coral red on sides; hind legs of lighter color than 
back with numerous spots of sepia brown; sides of thighs yel- 
lowish green; tail ringed with alternate bands of slate color and 
sepia; under parts white with pale brown spots on under sur- 
face of head. 
This species is not found in the immediate valley of the 
Rio Grande, or, if at all, very rarely, but is a resident of the 
lower parts of the mountain canons and the mesas adjoining. 
In habits it is similar to the preceding species. It is a beautiful 
and sprightly animal. How the C. baileyi, Stejniger is to be 
distinguished from this common form we are unable to say at 
this writing. 
Family. Anguidae. 
Tongue composed of two distinct portions, a principal pos- 
terior^parFcovered .with villiform papillae, and a small anterior 
portion, "^^whichlis thin, emarginate and retractile into the basal 
part. ^The][body^is protected by bony plates underlying the 
scales, the latter being imbricated and tuberculate. An occipi- 
tal plate is present. The teeth are variable and bear some re- 
semblance to those of the Gila monster. Skull with distinct 
nasals, ^single parietal. Abdominal ribs absent. Limbs some- 
times rudimentary. This family is most abundantly represented 
in Central America and the West Indies but is represented by 
the slow worm of Europe and by a few closely allied species in 
North America. 
Genus. Gerrhonotus. 
Limbs well-developed, pentadactyl; lateral fold present; 
scales squarish or rhomboidal, forming transverse series; eye 
large with a round pupil; no femoral pores or enlarged postanal 
plates; ear^opening distinct; no gular fold. A group of closely 
allied species of this genus occupies the entire western coast of 
North America, G. Coeruleus (G. scincicaudata) being the type.
