DENDROPHIS PRASINUS. \^l 



upwards of the subcaudal scutellae. The dorsal scales, which are 

 smooth, are disposed upon fifteen longitudinal series; the middle series 

 is composed of larger scales than the lateral series, from which they 

 likewise widely differ in shape. While the lateral scales are narrow 

 and elongated, the dorsal ones are subelliptically hexagonal. There 

 are four series of scales upon the tail at its origin, and one only towards 

 its termination. The abdominal scutellae, one hundred and sixty-nine 

 in number, are well developed, the preanal being entire like the rest. 

 There are one hundred and nineteen subcaudal scutellae, all divided, 

 else disposed upon a double series. 



The ground color is of a brownish-green, with a lateral yellowish- 

 white or whitish band extending over the two external series of scales 

 and bordered with black. The inferior black border covers partly the 

 outer series of scales and partly the abdominal scutellae, whilst the 

 upper one extends along the margin of the second series of scales. 

 The side of the head, in advance of the eye, is spotted with black. 

 The postocular and temporal regions, as well as the sides of the neck, 

 are black. The inferior regions are unicolor. « 



Log. — A specimen of this species, about three feet in length, was 

 procured at Singapore.
