| Diagnosis | Diagnosis: “Scale-formula 19-1917 ; ventral 191- 201 subcaudals, female 112-115 +1, male 112-122 +1. Colour pattern in juveniles consisting of an undulating dark vertebral stripe, a narrow lateral line, and dark spots on the flanks and hinder part of the belly. In adults the posterior part of the body is almost entirely black, but anteriorly the dorsal stripe is broken up into a series of large oval spots narrowly separated from one another ; the light interspaces may be fused on the sides of the neck to form a fairly distinct light stripe. Eleven specimens examined, seven females and four males. This form is readily distinguished from the typical form by the higher number of scales in front of the vent and the lower number of subcaudals in the male.
