Elena and others, 

Daniel is correct when the material is very dried; if it is sort of
pliable, just yielding a bit if you (very carefully) put some pressure
on it, then you might first try to use a weakish alcohol-glycerol
solution for a day or two.  This is a little less drastic and may do
less damage to the tissues if you need to do sections or something like
that.  Please remember that you will get out a distorted specimen no
matter what, so measurements and detailed morphological description may
be difficult, unless you can show that the rehydrated specimen matches
other, similar specimens.  If you use the soap solution, please be
careful to wash it out before tossing the beast in regular
preservatives.

Dear Elena and worm lovers,

A colleague working with insects told me that a good method to rehydrate

dried samples consists on using a few drops (or even only one, depending

on the size of the animal) of a common dish washing soap mixed with 
distilled water. The sample must be monitored very close, as the soap 
may destroy the most delicate tissues. I have not yet used that method, 
although I will try soon, as I also have an old, dried sample and the OK

from the museum curator.

I will let you know the results as soon as done, but if you decide to 
try first, please, share the results too ;-) .

Wormly,

Dani.
