Dorsal view of a Bungarus niger and b Bungarus lividus. The entirely black dorsum of both species distinguishes them from other South Asian kraits. In (a) B. niger the middorsal scales along the vertebral column (red arrows) are greatly enlarged and hexagonal in shape, whereas in (b) B. lividus the middorsal scales are similar in size and shape to those of adjacent scale rows (photo by Deb Prasad Pandey)
