Bcettger's Aden example of the species in having 24 instead of 22 

 rows of scales round the body, whereas out of the three specimens 

 now recorded 22 is the prevailing number. 



In all of these specimens the frontoparietals and frontal are 

 normal, also the supraorbitals.

In both the adults, the broken, more or less oblique or transverse 

 black dorsal bands, the breadth of a scale, are well-defined, 

 each dorsal and lateral scale included in the black band being 

 provided with the usual pure white narrow spot. In the smaller 

 of the two, the black bands with the white spots constitute 

 about 26 transverse dorsal bands, whereas in the larger specimen 

 they are nearly obliterated. In the young there are no black 

 bands, but many of the scales have a white spot margined with 

 blackish, but on the tail there are feebly indicated pale brown 

 dorsal bands with white spots, as in the last mentioned adult. 

 The coloration of these lizards thus conforms to that distinctive 

 of the typical form of this species.
