all other traces of the light lines having disappeared. Still 

 larger specimens show only the supralabial spotting, and in 

 the largest individuals even this is obscured. None of these 

 specimens has a red head, but the larger specimens have 

 more or less brick-red on scattered scales along the sides of 

 the neck and body and on the distal half of the tail. 



The color in life, June 17, 1920, of a fairly large speci- 

 men (C. A. S. No. 48,097) was as follows: Above, the neck 

 and body are a bluish gray faintly washed with copper or 

 brick red; many of the scales have blackish edges and some 

 have definite small red spots. Along the sides, from the 

 temples to the hind limbs, the deep brick-red pigmentation 

 forms an irregular band between the dorsal and latero- 

 ventral color areas. This red band has no definite edges and 

 becomes less continuous posteriorly. Below it are numerous 

 red spots on the pale yellowish olive latero-ventral ground 

 color. The head is colored above like the back, becoming 

 yellowish olive anterior to the frontoparietal plates. There 

 are faint white spots on the outer part of each of the four 

 larger supraoculars and the parietal plate. The upper labials 

 from the second to the seventh, are greenish olive with dark 

 brown posterior edges, and each has a central spot of green- 

 ish white. The lower labials are greenish yellow, with 

 slightly darker posterior edges, the second to the sixth show- 

 ing whitish central spots which are less evident than those 

 on the upper labials. All the lower surfaces except of the 

 hands and feet are greenish yellow, palest on the chin and 

 brightest on the tail. The upper surface of the tail is green- 

 ish lemon-yellow with some scattered red spots, and with 

 black edgings on many of the scales. The upper surfaces of 

 the forelimbs are red, of the hind limbs yellow faintly 

 washed with red. The lower surfaces of the hands and feet
