Z. Fuscus, Gthr. Plate XII, fig. 3. 



This snake, hitherto assigned to Borneo, is, according to 

 the opinion of Dr. Giinther, the same as a snake found by 

 Mr. Vinton in the jungle near Kangoon, and to which I 

 intended to have given the name of Z. fasciolatus. The 

 following is its description : — 



Scales 16, the 2 median rows faintly keeled. Ventrals 

 210, subc. 123. Head oblong, high ; gape wide ; eye very 

 large and prominent ; pupil round, iris dark green. Loreals 

 3. Labials 9 (5 and 6), the sixth extending high behind 

 the orbit. Dark green, with narrow fasciolated cross-bands 

 of lighter and darker colour, and yellow vertebral spot on 

 each ; posteriorly the cross-bands merge into a general 

 greenish black with 2 lateral rows of yellow spots ; under- 

 parts nearly black ; head dark green, with an appearance 

 of bloom, throat white, yellow orbital circle.

Scales 14 or 16, the 2 median rows keeled. Ventrals 

 189-199, subc. 92-98. Loreal single. Greenish anteriorly, 

 with a yellow, black-edged vertebral stripe ; posteriorly 

 black ; indistinct black lateral stripe.
