38. Ablabes Rappii, G ii n t h e r., (1. cit. p. 226). 



A fine specimen was obtained by my collector in the neighbour- 

 hood of Simla. It measures 23 inches of which the tail is 5 inches ; 

 ventrals 196, subcaudals 67 ; uniform dark bronze brown above, 

 yellowish white below, and on the lower part of the upper labials ; 

 chin and throat olive tinged ; loreal small, nearly twice as long as 

 high ; temporals 1 + 1 + 2, the first very long, the others much 

 shorter. 



39. Ablabes collar is, Gray, (G ii n t h., 1. cit. p. 228). 



This species appears to be rather rare in the low hills about 

 Simla. One specimen obtained near Subathoo measured 22| incites, 

 of which the tail is 7f inches; ventrals 184, anal bifid, subcaudals 

 113. General colour above greenish olive, head spotted with black, 

 a short indistinct cross black band at the anterior- another near the 

 posterior end of the vertical, a third curved one at the end of the 

 occipitals ; collar broad, black, edged with yellow posteriorly ; the 

 black spots forming the dorsal series on the fore part of the body 

 very small, almost obsolete ; tail with three blackish longitudinal 

 bands ; upper labials yellowish spotted with black, as is likewise the 

 chin and partially also the throat. Lower parts dirty greenish white, 

 purer posteriorly, each ventral and subcaudal with a black spot at 

 the base forming a more or less continuous black streak. 



The species also occurs near Darjeeling and in the Khasi hills.

 pressed, obtuse in front, scales smooth, in 17 series, ventrals 189,

 top of the head, two pairs of frontals, anterior broader than long, 

 about half the size of the posterior ; vertical subtrigonal, large, 

 with a very short point in front, and rapidly contracting posteriorly, 

 somewhat longer than the supraciliaries ; each occipital about one- 

 fourth larger than the vertical, and extending anteriorly as low as the 

 lower postocular ; nasals in two shields ; loreal united with the 

 postnasal of which only a trace is visible on the left side, on the 

 right side the postnasal is totally suppressed ; preocular one, large,
