No, Parasaurolophus is a very different genus.  It has either two
or three valid species (last I looked), one of which is known by
a single, probably female, specimen (Parasaurolphus curticristatus,
that is "short crested Parasaurolophus").

There are actually a number of genera of lambeosaurine hadrosaurs,
that is "hollow-crested deck-bills", the ones we have just discussed
are just the most widely known.

In addition there is a very large number of hadrosaurines, that
is "non-crested and solid-crested duck-bills".
