This is a male Whitesides guenon or Yellow nosed monkey, Cercopithecus ascanius whitesidei
His name was Paddy and I new him very well. He was one of a pair that were originally at Dublin zoo. They had been purchased from the Dutch animal dealer Van den Brink, mis-identified as greater spot-nosed guenon.
That is very interesting - thank-you. When Flamingo Land produced new labels in 1997 I was told they contained some mistakes as they had been produced by the marketing department rather than the zoo staff, but then presumably the former would have been relying on the latter to say what species were in the collection. He was living with a Sykes' Monkey at Flamingo Land.
