these are Annamese silvered langurs (Trachypithecus margarita) or Indochinese silvered langurs (T. germaini). The former was previously included within the latter. I'm not sure I could tell them apart unless in the wild (because the ranges do not overlap).
They are labelled as Silver Leaf Monkeys. Is this a possible synonym of your suggestions Chli? Wikipedia thinks that that might mean Trathypithecus cristatus.
They are in the huge domed concrete and bar enclosure, which I thought was beautiful.

no, not T. cristatus. Formerly cristatus was used for the whole complex (from Indonesia to Vietnam) but it was split into two (cristatus in the west and germaini in the east), and then margarita was further split from germaini. The separation between the two local species in Vietnam is the Mekong River, and the Saigon animals were caught within the range of margarita. If all the animals at the zoo are housed together they are probably all margarita - but they will be using the old [collective] common name (and quite possibly treating them as germaini if they don't accept/acknowledge the margarita split).
