The cage was labelled for Indochinese Black Langur (T. ebenus) and did hold one individual of that species, but also three Francois' Langurs and one other langur (pictured at the back in this photo) which is a wild hybrid between Francois' and White-headed Langur. It was very difficult to get proper photos because the glass was both dirty and very reflective in the sun. The size difference in this photo is not real - it is just the perspective because the hybrid langur is sitting further back than the Black Langur.
