(''Naja haje''), but morphological and genetic differences have led to its recognition as a separate species.
It differs from ''Naja haje'' in normally having more than 23 dorsal scale rows around the neck and a uniformly dark head without any obvious pattern on the supralabial scales.
Description
Adults are uniformly dark grey-brown dorsally, with slightly lighter lower flanks. The throat is also dark brown with occasional lighter individual ventral scales, whereas the rest of the ventral side is cream with dark grey-brown mottling. The head is dark grey-brown. Juveniles are grey with a black head and neck, and often carry a light blotch on the back of the hood. This normally disappears in adults, although a few specimens retain this marking into adulthood.
Size: a large, robust cobra, maximum recorded total length 245 cm.
