-No. 735, bright reddish to orange brown, darker anteriorly; 
belly bright reddish salmon, lighter anteriorly ; underside of head 
dusky, with milk-white spots; stripe on side of head cream 
yellow. The specimen was found crawling in the open along 
a path. Nos. 1781 and 1782 when taken were reddish brown

specimens were taken under rocks in the edge of a small brook. 
No. 1873 was taken under a log. The cream line on the side 
of the head has a pink area below it. Dim lines of minute 
yellow dots are present on each side of the anterior dorsal part 
of body; belly uniform coral to red. The blackish dots on the 
outer edge of ventral scales are associated with a small milk- 
white spot.
