The twins never mention in canon seeing the Basilisk on the map.
That would have borked the plot, and it’s entirely probable that Rowling hadn’t even come up with the Marauder’s Map by then.
In MoR canon it probably makes more sense if it doesn’t show up on it though; the whole Chamber of Secrets certainly doesn’t.
