 Cat. No. 10807, u.s.x.:vr. 



Head small; body rather stout. Black, with a dorsal ]\ght stripe, 

 and the usual two rows of lateral spot.s and stripe replaced by a single 

 series of distinct salmon-colored spots. 



Above, intense black, with a dorsal j^^reenish white line one and two 

 half scales wide, and extending from head to tip of tail. On each side 

 is a series of vertically elongated distinct spots of a reddish salmon 

 color, and seventy-five in number between the head and anus. They 

 occur on the second to the sixth rows of scales, and are half a scale 

 long, the same color being visible on the adjoinin.u' 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. 



This subspecies carries the fusion of colors further than the IJ. -s. 

 parietalis^ since thebelly is black. This color joins that of the inferior 

 series of black spots, and as the superior series are continent, the 

 intervals between the former are isolated. 



The tail in the only specimen where it is complete is one fourth the 

 total length. Gastrosteges, 103; urosteges, 8.").
