 as liigh as broad, scarcely visible from above; beliind the trun- 

 cated upper edge three scales of the same size as the other upper head 

 scales in a line between the anterior nasals and the first canthal scale; 

 four canthal scales between anterior misal and supraocular decreasing 

 in size posteriorly ; supraoculars wider than one-third the interocular 

 space; 8 scales on a line between the supraoculars; head scales flat, 

 smooth anteriorly, faintly tubercular or keeled on parietal and occip- 

 ital regions; nostril large, rounded, in posterior margin of anterior 

 nasal wliich is much larger than posterior, its upper anterior edge just 

 visible from above, but not turned over the canthal edge; a small 

 loreal, nearly twice as long as high below second and third canthal 

 scales, in contact behind with the two preoculars, of which the upper is 

 twice as wide as the lower; pit very large; subfoveal shield entering 

 eye below preoculars; eye rather small; three small suboculars 

 separated from supralabials by two scale rows; two postoculars; 

 temporal scales numerous, the upper ones small, keeled, the lower 

 series next to the supralabials larger, smooth; 8 supralabials, first 

 small, triangular, separated from loreal by one scale, second broad, 

 forming anterior border of pit, third largest; two lower labials in 

 contact with anterior chin-shield; posterior chin-shield scarcely differ- 

 entiated; 23 rows of rather obtuse scales with obscure apical pits; all
