Remarks. This leaf-monkey also occurs in Western Siam 
from Sisawat (vide Gairdner Joc cit.) to Raheng, from which neigh- 
bourhood I have received a skin collected by Messrs. Elwes and 
Yates. It is probably Tickell’s S. phayrei from “ east of Moulmein,” 
of which a description and figure are given by Blanford (Faun. 
Brit. Ind. Mamm., p. 41, fig. 10). 
Freshytis phayrei (Blyth) of Arakan (of which I have 
examined the type series in the Indian Museum) is a very different 
animal, being white or yellowish white below and brown elsewhere, 
paler and silvery across the shoulders and darker or blackish on 
the forehead and the extremities of the limbs. Its crest is an 
erect compressed ridge curling slightly backwards, but the hair of 
the head shows no sign of radiating.
