Four supralabials distinct ; the third very high and bandlike, in 
contact behind the eye with the supraocular and the parietal scale, 
the fourth smallest, squarish. Mental large, nearly twice as broad 
as long. Four sublabials, the anterior pair the largest and sepa- 
rated from each other in the median line by a small shield which is 
followed by three others, the middle one of which is the smallest. 
Headshields thickly dotted with minute papillae. Scales smooth.

Typhlops-like, in twelve series round the body. Praeanals not 
enlarged. No external rudiments of limbs. Tail one third as long 
as the body, terminating in a circular scale. 
Colour (Spirits) : — Body light greyish brown above, slightly 
lighter beneath. Longitudinal rows of faint spots on the dorsal 
and lateral scales, these spots fainter and the rows more numerous 
on the sides. Headshields with faint brown marks. Tail yel- 
lowish, the rows of spots of a reddish colour. 
Total length 145 mm.. Tail 45 mm. 
This new species is distinguished from 0 . nasuta, Bocage, 
mainly by the longer snout, which is hooked in profile ; the much 
larger nostril and the presence of a very distinct groove which con- 
nects with the praefrontal, not with the first supralabial ; the different 
proportions and shapes of the headshields, which in 0. repens are 
covered with minute papillae, and the smaller number of scales 
round the body. The two species are here compared side by side.
