Head rather strongly depressed, its depth equalling the distance between the centre 
of the eye and the anterior border of the eye, its length once and a half or once and 
two-thirds its width ; snout pointed, as long as the postocular part of the head. 
The hind limb reaches the shoulder; foot once and one-third or once and two-fifths 
the length of the head. Tail nearly twice as long as head and body. 
Rostral not entering the nostril; postnasal single; frontal nearly as long as its 
distance from the end of the snout; series of granules between the supraciliaries and 
the supraoculars incomplete, the first, or first and second supraciliaries in contact with 
the second supraocular ; parietals once and one third as long as broad, in contact with 
the upper postocular; occipital a little shorter and a little broader than the inter- 
parietal ; temporal scales granular, with a moderately large masseteric disk ; tympanic 
shield distinct ; supratemporal shields small (3 to 6); four anterior upper labials in 
the specimen from Oxia, five in that from Platia. 
Collar with even edge; gular fold distinct. 
Dorsal scales very small, roundish, convex, faintly keeled granules; 3 or 4 
correspond to one ventral plate, 42 or 43 to the length of the head. Preanal plate 
rather small, with 2 or 3 semicircles of small plates; in the specimen from Platia it is 
followed by a series of granular scales, as sometimes occurs in the var. serpa (see 
Pl. XXI. fig. 50). Scales on upper surface of tibia feebly keeled, a little smaller than 
dorsals. 
Upper caudal scales moderately keeled, truncate, very diagonal to the keel, 30 or 31 
in the fourth whorl behind the postanal granules. 
Greyish olive above, uniform or with very faint darker reticulation, white beneath, 
outer ventral shields bluish grey; a blue, black-edged spot may be present above 
the axil.
