specific value but merely individualistic. The “generally browner 
color” of P. n. keatu, pertains to such examples of P. FEMORALIS as 
have not assumed the fully adult dress which is black, and the length 
of the abdominal white line varies among individuals, and cannot be 
relied upon as a specific character. P. FEMORALIS ranges in the Malay 
Peninsula north to Tenasserim, and it is not reasonable to believe that 
a distinct subspecific form is found within that species’ limits, espe- 
cially one so slightly differentiated as P. n. keatu. It is therefore 
considered as a young adult of the present species and the name placed 
among its synonyms. 
Flower states, (1. c.) that “in September 1897, in the woods 
among the foothills of Gunong Puli, Johore, were many Lutongs of 
this species going about in flocks; they were shy and difficult to see 
except for a glimpse of a black form disappearing from one high tree 
to another.” 
Hose (1. c.) says that “this monkey is a low country species 
seldom to be found on the mountains, and then only ascends to about 
1,000 feet. It is fond of living near the sea shore, and is generally 
found in numbers of from ten to thirty, sitting on the branches of tall 
trees in open spaces. Its Dyak name is ‘Bigit,’ that of the Kyans 
‘Pant.’ ”
