broader than high, scarcely reaching the upper surface of the 

 head. Anterior froutals half the size of the posterior. Ver- 



tical rather broad, with the lateral margins convergent, equal 

 in length to the anterior. Occipitals rather small. One 

 loreal shield only, square ; one preocular, extending onto the 

 upperside of the head, but not reaching the vertical. Two 

 postoculars. Eight upper labials, the fourth and fifth enter- 

 ing the orbit. Temporals scale-like, 2 + 2 + 3. Scales lan- 

 ceolate, much imbricated, smooth, in nineteen rows. A^en- 

 trals without any keel, 156-160 ; anal bifid, subcaudals 69- 

 72. The maxillary teeth slightly increase in length poste- 

 riorly ; but the hindmost is considerably larger than the others, 

 and there is no vacant space between it and its predecessor. 



Brownish olive above, with an indistinct lighter line from 

 each occipital along each side of the anterior half of the body ; 

 the lower parts are whitish or reddish, with numerous small 

 blackish spots ; these spots have a tendency towards forming 

 regular longitudinal series, three bands being thus formed in 

 one of our specimens, one along the middle and one along 

 each side of the belly. An oblique black stripe runs from 

 the eye to the angle of the mouth. 



The largest of three specimens is 37 inches long, the tail 

 measuring 8 inches.

 long or nearly as long as an occipital. Loreal higher than 

 long, two pre- and two postoculars. Eight upper labials, the
