7th labial, and extends along to the angle of the mouth : the ends of 

 the anterior lines on opposite sides scarcely appear to meet on the 

 top of the head. The vitta between these two light lines is dark 

 ash, margined with black, and passes back above the labials to the 

 angle of the mouth. The space in front of the second line is black, 

 except a short narrow line produced along the labials anteriorly as a 

 branch of the line in front of the eye. Edges of the nostril light. 



The animal is quite young,, there being but a single button. 



An important feature of distinction from C. adamanteus is seen in 

 the fact that the dark line on the side of the head passes above the 

 labials to the angle of the mouth, instead of passing very directly 

 down to the edge of the mouth, considerably anterior to the angle. 

 The sharpness and close approximation of the rhomboids distinguish 

 it from the other Western species. The head is much longer in pro- 

 portion than in C. lucifer.

Head small ; body rather stout. Outer row of scales higher and 

 larger than the rest, which are nearly equal. Above intense black, 

 with a dorsal greenish white line one and two half-scales wide, and 

 extending from head to tip of tail. On each side is a series of verti- 

 cally elongated distinct spots of a reddish salmon-color, and 75 in 

 number, between the head and anus. They occur on the 2d to the 

 6th rows of scales, and are half a scale long, the same color being 

 visible on the adjoining skin. The dark intervals are one scale 

 longer than the spots themselves. Beneath greenish black, tinged 

 with white anteriorly. Whole head reddish yellow, tinged above 

 with brown.
