The Fr. form ouanderon (Buffon) is a re-spelling of the word as given by Knox.] A name properly belonging to the langur monkeys (genus Semnopithecus), inhabiting Ceylon, but until recently almost always misapplied, after Buffons example, to the Lion-tailed Macaque (Macacus silenus) of Malabar.

1907. Times, 21 Aug., 2/4. Mr. George Benzie has presented a lion-tailed macaque (Macacus silenus), often miscalled the wanderoo, a name which of right belongs to the purple-faced langur (Semnopithecus cephalopterus) of Ceylon.
