terior nasal being hollowed out as is also the loreal though to a less ex 

 tent, the two nasals and the loreal subequal in size; eye large, its hori

 diameter greater than its distance from the edge of the lips; eye sur 

 rounded by a ring of 10 (or 11 on one side) shields including the supra- 

 oculars; temporals 2 + 3; 8 supralabials, sixth and seventh largest; 

 mental very small; 9 lower labials, first pair large, broadly in contact 

 behind mental, first, second and third in contact with chin-shield; only 

 one pair of large chin-shields, in contact behind with four scale-like 

 shields, the outer pair of which, which represent the posterior chin- 

 shields, scarcely more developed than the others; 25 rows of scales

 a brownish-black band across the pref rentals, with an anterior projection 

 on the suture between the internasals, this prefrontal band extending 

 obliquely backwards through the eyes to the angle of the mouth; a simi 

 lar band running parallel with it from the parietals to the sides of the 

 neck joining a large oblong blackish patch on each side of the neck; be 

 tween these, on the nape, an elongate median blackish spot; a brownish 

 black symmetrical figure of irregular outline on fronto-supraocular- 

 parietal suture; a pale irregular band spotted with dusky across middle

The young specimen (U. S. N. M. No. 32,089), apart from slight devia 

 tions in the scale formula, which may be seen in the subjoined table, 

 agrees completely with the two large specimens. Its ground color is less 

 brownish, inclining as it does to purplish gray, and there is an additional 

 lateral row of irregular blackish spots below the ocelli of the dorso- 

 lateral cross-bands.
