DiagnosisOriginal Description: Head rather long and narrow. Ear distinct. Internasal and frontal plates equal, the suture between them straight no fronto-nasals; a pair of fronto-parietals, nearly as long as the frontal, in contact throughout their length; interparietal large, broad; parietals large, pentagonal; two postparietals. Nostril in middle of a large nasal plate, which is followed by a quadrangular frenal. An elongate plate at the angle of the mouth, and five supralabials temporals large, polygonal. Submental elongate, followed by only two pairs of contiguous postmentals a third pair are widely separated by a group of wedge-shaped and pentagonal plates, which occupy the rest of the space as far as the first gular row of scales, of which there are three small and three large before the collar. Dorsal scales narrow, elongate, cach scale elevated into a ridge in the middle, in 36 transverse series between the occi put and the root of the tail; scales of the sides much smaller, round, convex or granular on side of neck and axillary region; of belly in 10 longitudinal series, the middle ones square, the outer oues narrower. Tail with scales like the back and the belly. Preanal scutes 2, 4. The fore limb reaches to the middle of the eye, the hind limb two thirds the length of the side.” (O’Shaughnessy 1879).

Coloration: “Brown above; a longitudinal stripe of lighter brown edged with black on each side of the back from the occiput to the tail. Ten or eleven conspicuous ocelli, white in the centre, and surrounded by a black ring, along the side of the body; beneath each one of these a smaller white spot is visible. All the ventral scutes and those of the under surface of the limbs black in the middle, white on the edges, the black forming longitudinal stripes.” (O’Shaughnessy 1879). 
EtymologyThe specific epithet, oculatus, is a Latin adjective that means "adorned with eyes" and probably refers to the lateral ocelli in the dorsal color pattern of this species.
