 This subspecies is quite distinct in appearance from the U. s. sirtalis 

 ill lite, and may be also readily distinguished in spirits after the disap- 

 pearance of the bright red colors. 

 It has also a definite geographical 

 range. 



Form more slender than in the 

 U. s. sirtalis; head quite distinct. 

 Squamation identical with that of 

 E. s. sirtalis. Gastrosteges (of 

 Cat. No. 8738), one hundred and 

 sixty-seven; anal, one; urosteges, 

 eighty-eight. In Cat. No. 8737, 

 gastrosteges, one hundred and 

 sixty-two; anal, one; urosteges, 

 eighty-live. Eelative length of 

 tail in Cat. No. 8378 (2 specimens), 

 three and seven-eighths times in total length; in Cat. No. 8737, four 

 and one-eighth. 



Measurements. — Total length, 576 mm.; length of tail, 145 mm. 

 Lower surfaces and lateral stripe olivaceous ; gastrosteges with a small 

 black spot near each end. Dorsal stripe red, with a delicate black or deep 

 brown border on each side. Space between dorsal and lateral stripes 

 brown, marked with a single series of small black spots, which occupy 

 parts of three rows of scales next to the lateral stripe, and do not, there- 

 fore, reach the dorsal stripe. Spaces between the lateral spots red. 



The gastrostegal spots are smaller than in the E. s. sirtalis, and are 

 more isolated and rounded; sometimes they aie not present on some of 

 the gastrosteges. The labial plates are very little or not at all black- 

 bordered. Parietal sjwts distinct.
