98 PYGATHRIX 
Specimens from the Coromandel Coast are much grayer than 
those from Ceylon, these being a vinaceous. brown above. Whether 
these differences in color indicate the existence of a race separable 
from the typical form, would require more examples than are at 
present available to determine satisfactorily, and the problem will have 
to remain for Indian Mammalogists, who are on the ground, to solve. 
Blyth described this species as having a high, compressed vertical 
crest, but Anderson (1. c.) has stated that the crests of specimens in 
the Calcutta Museum were produced artificially, in one case by cotton 
wool placed beneath the skin, and in another by a wire, in both cases 
the result of unskilled taxidermy. : 
On the other hand Blanford states in a footnote, that in three 
dried skins from Ceylon in the British Museum, the crest was dis- 
tinctly shown, and that he had also seen it in skins from Southern 
India and he was assured by Davison and others that it was constantly 
present. 
The type of P. thersites came from Ceylon and agrees with other 
individuals from that island considered the same as P. PRIAMUS. — 
Subgenus Pygathrix. 
Size large, body robust; limbs of nearly equal length; facial
