times merely turned up as in the former, sometimes ending in a 
dermal appendage or ‘horn’ which is but little less developed than 
in the latter. Rostral once and a half to twice as deep as broad, 
nearly reaching the tip of the rostral wart; 5 or 6 (rarely 3) scales 
on the posterior aspect of the latter; head covered with small, 
smooth, or feebly keeled, subimbricate scales, among which a slightly 
enlarged frontal may sometimes be distinguished; 5 to 7 longitu- 
dinal series of scales between the supraoculars, which are well 
developed ; 9 to 13 scales round the eye, usually 10 to 12; two or 
three series of scales between the eye and the labials ; nasal entire, 
separated from the rostral by a naso-rostral; temporal scales smooth 
or feebly keeled; 9 to 11 upper labials; 4 or 5 lower labials in 
contact with the chin-shields. Scales in 21 rows, strongly keeled, 
outer row smooth or feebly keeled. Ventrals 125-146 in ¢, 
135-147 in 9; anal entire; subcaudals 35-43 in ¢, 32-35 in 9. 
Grey or brown above, with a dark brown, usually black-edged 
undulous or zigzag band along the spine and a lateral series of 
spots; head with or without small dark markings above, and a
