Indeed, though I'd be more inclined to suggest they are a Brown Lemur with a little White-fronted blood, as opposed to vice versa, judging by some of the more obvious phenotypical characteristics.
The faces of these lemurs are wrong for E.mongoz, which tends to have pale-to-white snouts and (depending on gender) very pronounced white or red beards.
Moreover, the bodies are also wrong - E.mongoz tends to be a charcoal grey colour, with the females also having chestnut coloured back portions and rear legs.
