Help find a missing monkey

My colleague at Global Conservation Institute is setting off on an expedition deep into the Amazon to find a missing monkey species that has not been seen since the 1930's. Setting off in a house boat down several rivers and then into the flooded forest a team will be searching for a rare, and hopefully not extinct, saki monkey. However, gas for the boats is expensive. The team has a site on Generosity under Houseboat Amazon to raise money for the the petrol.
