Description

''O. elegans'' has the following distinguishing characters: Head moderate, feebly depressed. Upper head-shields smooth or slightly

rugose Rugose means "wrinkled". It may refer to: * Rugosa, an extinct order of coral, whose rugose shape earned it the name * Rugose, adjectival form of rugae Species with "rugose" in their names * ''Idiosoma nigrum'', more commonly, a black rugose tra ...

; nostril lateral, pierced between on upper and a lower nasal, and followed by one or two postnasals; frontonasal single; four supra-oculars, first and fourth very small, the two principal separated from the supraciliaries by a series of granules:

occipital The occipital bone () is a cranial dermal bone and the main bone of the occiput (back and lower part of the skull). It is trapezoidal in shape and curved on itself like a shallow dish. The occipital bone lies over the occipital lobes of the cere ...

small, in contact with or separated from the interparietal; subocular bordering the lip, normally between the fourth and fifth upper labials; temporal scales small, smooth; usually two large supratemporal shields bordering the parietal; a large tympanic shield. A. gular fold may be distinguishable; collar absent or feebly marked. Dorsal scales variable in size, as large as or larger than the laterals; 30 to 40 scales round the middle of the body, ventrals included. A more or less enlarged postero-median preanal plate. The hind limb reaches about the ear in the male, the shoulder or a little beyond in the female. 7 to 12 (usually 9 to 11) femoral pores on each side. Tail about twice as long as head and body. Olive or bronzy above, with black spots usually forming longitudinal series, sometimes forming a network; frequently and or two light longitudinal streaks on each side; lower surfaces white. From snout to vent 2 inches (5 cm); tail 4 inches (10 cm).
