This female shares an exhibit with talapoins. As tomek mentions in his photo below this is the last one in Europe. There are most likely none left in the U.S. either. There was no signage on this species on the exhibit, if i had not seen Tomek´s fine photo i would have missed this interesting primate.
According to the Barcelona zoo webpage, which is actually quite nice and usefull, the english name is Greater Spot Nosed Monkey, latin name Cercopithecus nictans martini.
