I am inclined to agree with Anderson, who unites them, and who 

 fortunately was able to examine and describe the type of the last- 

 named form, now no longer to be found. That the Sikhim monkey

 'and differ in fur, coloration, visage, and habits, and I think the 

 limbs are proportionally shorter.
