HYLOBATES 171 



taken from the supposed type in the British Museum, a mounted 

 specimen, as none marked Type was found. Other specimens in the 

 collection, have black only on the crown, and from lower part of 

 breast to end of abdomen ; or on whiskers, spot on throat, chest and 

 abdomen, all the rest of the pelage being brownish or pinkish buff 

 above, and yellowish white on under parts ; but no matter how much 

 the black may have disappeared from the other parts of the body, the 

 belly is apparently always of that color. 



"At Paknam Kabin," says Flower, (1. c.) "in Siam, in 1897, there 

 was a pet gibbon of the variety pilcaius, said to have been caught in 

 the neighborhood. Its color was buffy white, except the hair on the 

 top of the head, which was black, and on its chest which was very 

 dark gray. The skin of the face, and palms of the hands and soles of 

 the feet were black."
