Luckie:

But why didn't the twins ever notice Pettigrew when they had the 
map? Ron was in his third year in PoA, they had had the map since 
their first year, so they had 2 full years in which to stumble on 
Pettigrew's name. The only thing I can think of is that 1) they 
didn't know who Pettigrew was (Although I think they did - can 
anyone find them mentioning Sirius's supposed crimes in canon?) or 
that, like Harry, they were simply looking at the part of the map 
they needed to escape at that particular moment - which wouldn't 
have been gryffindor tower, where Peter was.
