M. stuarti can grow to a total length (including tail) of 74 cm (29 in), but most are closer to 50–60 cm (20–24 in). Its color pattern consists of 13–19 relatively broad black rings and very broad red rings, separated by narrow yellow rings. The dorsal scales are smooth, and the red ones are black-tipped. The number of broad black rings on the tail may vary from 3 to 4, separated by narrow red-brown rings.
