My 7. k. williamsont from North Siam! is not only larger 
but has the upper parts less blackened and of a deeper, more tawny, 
colour with paler, narrower throat markings; the palatal extension 
is shorter and broader, but the external biorbital breadth is about 
the same. TZ. k. angustiae? from S. Tenasserim and §. W. Siam is 
rather more brightly coloured and has the nuchal stripe dark and 
distinct.

AN ALTERNATIVE NAME FOR PRESBYTIS GERMAINI MANDIBULARIS. 
For the benefit of those who follow Mr. Oldfield Thomas in 
the use of Pithecus as the generic name for the langurs or leaf- 
monkeys, I name the animal of Koh Chang 8. E. Siam, Pitheeus 
yermatni changensis as well as Preshytis germaini mandibularis, 
under which its description will be found in P. Z.8., 1916, p. 32. 
The combination Pitheeus mandibularis is preoecupied, having been 
applied by Elliot to a macaque from Western Borneo (Proc. U.S. 
Nat. Mus., 38, 1910, p. 347); as, therefore, whenever the Koh Chang 
leaf-money is placed in Pifheews it will be without a name, I provide 
it with one as above,
