 Upper labials six, vertical six-sided, sornewhat more long than 

 broad. Temporals 1 + 1 , the posterior longer and narrower than the 

 anterior. Ventrals 225. This species bears sorae resemblance to E. 

 bivirgatus Boie, as regards the general colour of the back and that ot 

 the belly. In coloration, however, the difference between the two species 

 is very important. Our only specimen has the tail mutilated just behind 

 the anal shield, so I am unable to give any information as to the 

 shields or coloration of the tail. In the beginning the belly is ofared 

 colour uniform without dark spots, the 73 rJ ventral is the first that 

 assumes a black colour, though only on its left half. Again 30 ventrals 

 are uniform red, the 31 st is quite dark, followed by alternately black 

 and red cross bands, the latter colour occupying 4 or 5 ventrals, whilst 

 the former colour occupies half a ventral, one, one and a half, or two, 

 in one instance even three ventrals. The upper parts are of a violet 

 colour with a glossy shiue and witli three dark longitudinal bands, one 

 occupying the three series of scales on the middle of the back, and 

 one on each side occupying the three outer series of scales. Upper 

 parts of the head of a dark colour, except the posterior frontals, which 

 are sornewhat lighter than the rest of the shields.
