PYGATHRIX 75 



This is a very large monkey, a giant by the side of either P. johni 

 or P. CEPHALOLOPTERA, but in color resembling the former almost 

 exactly. It is confined to the mountainous portions of Ceylon. 



Kelaart states that this species is "usually seen in large numbers 

 jumping on the trees, and when disturbed make a short howling noise" ; 

 while Tennent says that "at early morning, ere the day begins to dawn, 

 their loud and peculiar howl, which consists of quick repetition of the 

 sound kow-kow, may be frequently heard in the mountain jungles." 



Subgenus Trachypithecus.
