This is a very remarkable species, allied in some respects to the 

 members of Rhinopithecus, but very distinct from them both generically 

 and specifically ; and if it had not been overshadowed by the large 

 size and brilliant or striking coloration of those animals, would doubt- 

 less have been considered one of the most remarkable discoveries
