“‘ Scales in 17 longitudinal rows, smooth on the anterior half of 
the body ; posteriorly a few dorsal rows with faint keels, becoming 
stronger towards the tail, and extending on all the scales near the 
anal region, where they are tuberculous as in Aspidura trachyprocta. 
Tail nearly one third the total length. Occipital [=parietal] plates 
large, almost reaching the labials in front, posteriorly acuminate ; 
vertical [ =frontai] long, acute behind; superciliaries large, promi- 
nent, broad behind. Postfrontals [=prefrontals] small, their 
anterior outline regularly curved; prefrontals [= internasals] 
small, quadrangular. MRostral nearly rectangular, not appearing on 
the surface of the head. Postnasal high, its apex visible from above, 
opposite the suture between the pre- and postfrontals. Superior 
labials seven, eye resting on third and fourth. Inferior labials 
nine. Geneials two pair, the anterior shorter. Gastrosteges 127, 
urosteges 85. Above and below reddish brown, paler in the centres 
of the gastrosteges. Every fourth scale of the fifth row on each 
side pale, the adjacent scales on the fourth and sixth rows generally 
darker. Top of the head much lighter, varied anteriorly; palest 
behind the eye and above the labials. The latter are dark with a 
few light spots.”
